Abstract
The invention discloses a jet reducing power machine of a jet automobile, which relates to a power machine which can reduce the jet speed of the jet automobile and is also called a low speed jet engine. The jet reducing power machine of the jet automobile mainly solves the problem that the difference of the velocity of the low speed automobile relative to the high speed jet velocity is large and the kinetic energy consumption is high. The main technical means is that the difference of the jet velocity and the steering velocity of the automobile is reduced and gradually tends to zero by specific methods. Specifically, a second pressure tank is connected with a first pressure tank through a control valve and a mechanical device. The first pressure tank is an air storage tank. A power valve and a resistance power plane with larger areas are arranged on one side of the second pressure tank. After the power valve is opened, the power can be gained from the air jet backwards, and while the valve is opened, a forward reacting force power can be gained from the resistance power The opened power valve gains power from the resistance power plane moving backwards, by this way, a contact area between the valve and the air behind is increased and the loss of jet kinetic energy is reduced, and meanwhile, the energy conversion efficiency is increased and efficient energy-saving is realized.
Description
Technical field
Relate to the jet deceleration power engine of a kind of jet-powered car.
Background technique
April 11 in 2012, Japanese publication people proposed the patent application of pressurized air jet-powered car to Patent Office of State Intellectual Property Office, proposed pressurized air jet-powered car more energy-conservation than compressd-air motor.Application number: 2012201510991, title: the non-turbojet motor of a kind of air compression type or automobile.
June 25 in 2012, Japanese publication people proposed " pressure slow releasing apparatus of pressurized air jet-powered car " patent application to Patent Office of State Intellectual Property Office, application number: 2012102111777, relate generally to the developing direction that solves new-energy automobile, and propose the problem that " pressure slow releasing apparatus of jet-powered car " slowly discharges pressure to change the size of jet face.In these application documents, mention following problem: 1) in air, PM2.5 derives from fuel automobile.2) environmental pollution comprises chemical contamination and physical contamination, chemical contamination comprises that acid toxic gas pollutes, PM2.5 particle contamination, physical contamination mainly refers to that the mankind consume " thermo-pollution " that the solar energy energy in addition produces earth environment, " thermo-pollution " refers to that the earth is because consuming extra heat and the enormous amount producing of the energy beyond solar energy, cause ambient temperature to raise, cause atmosphere moisture content to increase, additionally cause heavy rain, strong wind, debris flow and seismic frequency to increase.3) approach that solves above-mentioned pollution is to change energy utilization patterns and energy-conservation.4) policy of the existing new-energy automobile of China is electric vehicle, but there is defect and can't resolve at present and also forever can't resolve in the future in the battery of electric vehicle, reason is: electric power has the feature of instantaneity, be applicable to remote transmission, be not suitable for storing, this is because electric power " strong mobility " determines, electric power has " kinetic energy " and " potential energy " equally as the one of the energy, electric current is realized the quick transmission of kinetic energy, potential energy is applicable to storing, in other words the storage of electric power must be between the both positive and negative polarity of battery, and between both positive and negative polarity, do not have absolute insulator therefore between both positive and negative polarity, must have electric current to certainly lead to power consumption by producing heat, therefore the energy of battery has self-consumption characteristics, therefore battery is in charging, deposit and in process, all have the spontaneous consumption of a large amount of energy, and for a certain battery, battery storage is more will produce larger oneself's consumption, therefore, from using energy source angle, the new-energy automobile of battery is difficult to support the development of following power vehicle in theory, only can be used as supplementing of a kind of power source source.5) compressed-air power accumulation of energy better and have a higher specific energy, claimant measuring and calculating: when compressed-air actuated pressure reaches 60MP when above, its energy density per unit volume approaches the liquid fossil-fuel energy (diesel oil, kerosene, gasoline) etc., and when 20MP, its energy density per unit volume is not as good as 1/10th of oil energy.6) Compressed-air Powered Vehicle is divided into pneumatic motor automobile and jet-powered car, and jet-powered car, except equally having with aircraft jet power the technical order that part is identical (such as thrust), also has more energy-conservation advantage.
But after after a while, today, claimant thought that the energy-conservation of jet-powered car is not absolute, but with good conditionsi, simple jet be not under any condition, all to realize energy-conservationly, utilize bad not only not energy-conservationly, also can cause the meaningless waste of the energy.This is that under automobile lower-speed state, jet-powered car ejection high-speed gas is just not energy-conservation because jet-powered car and jet-propelled rocket, aircraft, guided missile are more often in the state of " low speed " and " constantly slowing down " and " often starting ".So how, just energy-conservation? be what is the energy-conservation condition of jet-powered car? this condition is exactly that the velocity amplitude of automobile and the difference of gas jet velocity amplitude are less or equal zero, wherein the velocity amplitude of automobile refers to automobile movement velocity value relative to the earth, the velocity amplitude of gas jet refers to the velocity amplitude of gas jet with respect to operation automobile, the difference of velocity amplitude is less refer to less with respect to the velocity amplitude of gas jet.(velocity amplitude just refers to speed, only have size, there is no direction, be different from " speed ", as follows). when automobile low speed and when gas jet high speed operation, the energy consumption of pressurized gas is on the kinetic energy of gas jet, and gas jet speed is higher, and pressure is larger, its range ability is far away, according to law of conservation of energy, the energy of compressed-air actuated stored energy consumption in gas jet is higher, and the energy that the automobile that utilizes gas jet reaction force to advance obtains will reduce relatively.In the time of the speed of gas jet and the motion speed opposite sign but equal magnitude of automobile, gas jet does not have speed relative to the earth, therefore thinks that gas jet does not have kinetic energy consumption.Now can think that the energy transformation ratio of jet-powered car reaches 100% in theory.But under normal conditions, automobile needs starting, acceleration, deceleration, low cruise conventionally, jet velocity value difference value with respect to gas is huge, under normal circumstances do not do to gas jet speed control process in the situation that, automobile places an order net income gas jet in the situation such as low cruise, starting can't be energy-conservation as power, therefore also someone will reach a conclusion: gas jet is not suitable for the automobile of low cruise as power and is only suitable for aircraft or the rocket of high speed operation.In fact current gas jet also on the multiplex aircraft at high speed operation, rocket and guided missile.Therefore, consider merely according to law of conservation of energy and momentum conservation law, jet-powered car is not energy-conservation in the time of low cruise.But, claimant thinks: the speed of gas jet refers to the speed with respect to automobile, and the height of gas jet speed can be controlled, when gas jet speed drops to below 100 meter per seconds (360 kilometers/hour), the motion speed of automobile (or other power car and boat) can be with the velocity amplitude of gas jet (speed) difference in 360 kilometers/hour (100 meter per seconds) not too large and jet velocity can change according to the variation of car speed.If automobile instantaneous velocity value is V1, car mass M1, jet velocity value is V2, in unit time, the quality of gas jet is M2, compressed-air actuated energy changes into the efficiency of automobile kinetic energy and is inversely proportional to (V2-V1) 2 value, be directly proportional to M1/M2, therefore, can design the velocity amplitude that changes operation gas jet, make close to operation automobile or other operation aircrafts, rocket, guided missile, steamer, the motion speed value of train, as long as the active force of its gas jet is greater than running resistance and (comprises frictional force, resistance of air, fluid resistance), the aircraft of automobile or other operations, rocket, guided missile, steamer, train just can start gradually, Accelerating running, therefore, the speed of gas jet and the reaction force of gas jet size as operation automobile are exactly two key technology factors in design.The speed of gas jet and gas jet reaction force can change along with the variation of the motion speed of automobile, objectively need the equipment of gas jet to meet this variation requirement.
For this reason, sum up above content and according to law of conservation of energy and motion theory of relativity, the applicant proposes " relativistic theory of energy ", and under this theory design technology project, the Conversion of Energy of gas jet is maximized.After all be exactly the maximization problems that solves jet-propelled motive power machine device Conversion of Energy, final realize the transformation that realizes energy-conservation and energy utilization patterns in water at sports apparatus such as the rocket of the automobile of land locomotion, train, the steamer moving, submarine, airflight, guided missile, aircrafts.
The basic theories of energy: energy partition is a scalar in momentum, there is no directivity, has an absolute figure.Energy partition, in power, does not have point of action, but has carrier, has how many relatively not the having greatly and little comparison of value.How many energy and actings link together, can do how many merits and just think it has how many energy, energy is divided into kinetic energy and potential energy, for the moving object with the certain kinetic energy of certain mass, the minimizing of its energy value be Describing Motion object space under the effect of certain resistance change procedure total amount (be kinetic energy change be because resistance cause acting amount number), be the description of the object running space to certain mass; Potential energy be object of which movement ability to certain mass and movement tendency description (be potential variation cause acting amount number), energy is observed law of conservation of energy in transmittance process.Be energy when be delivered to another or multiple article carrier by an article carrier, energy input value equals output value, but because a single object cannot only contact another single object at movement process the whole story, but other objects outside an object are contacted and have been delivered to, (constraint of breaking away from power such as object starts to do the movement of falling object, in movement process, want ingress of air, and in reality, there is no absolute vacuum, motion finishes also will clash into or contact the earth and carry out Conversion of Energy) still energy by an object transfer during to another object, conversion ratio cannot reach 100%, but portion of energy has been delivered in other article carrier, analyze and reduce the energy consumption numerical value of other objects, it is the foundation that improves energy conversion efficiency.
The relativistic theory of energy: motion is relative (having reference system), energy is the same with " acting " is the description of the ability to space total amount, so energy is also relative (having reference system), this is literal logic reasoning, and this " relativity " indigestion.So how, do you understand energy and there is relativity? first see such example.An apple comes off and lands from tree, first base of fruit can't bear apple weight heavy burden fracture after free fall, before whereabouts, there is gravitational potential energy, can gravitational potential energy all change the kinetic energy before landing into so? in Middle School Physics, conventionally do not consider resistance of air, therefore can not consider the energy loss that apple lands in process, in fact apple is liftoff not far, the free fall time for acceleration is short, speed is less, resistance of air is not too large, while landing, the less event of resistance of air relative gravity resistance of air is ignored, can simply think that the gravitational potential energy of apple has all been transformed into kinetic energy when apple lands.But the shape of real moving object and density are had nothing in common with each other, such as the large thinner aluminium sheet of area is in the time that large size ingress of air falls, resistance of air now just can not be ignored, such as parachute, parachute declines and starts to have gravitational potential energy with respect to the earth, but it is not very large that parachute drops to the kinetic energy ratio that ground potential energy changes parachute into, where has the gravitational potential energy of the parachute in declining so gone? the gravitational potential energy of parachute does not all change the whereabouts kinetic energy of parachute into, but forwarded that parachute contacts with parachute below to or the motion energy of the motion air of mediate contact on, therefore, shape that just must consideration object moving when the affecting of object moving on air when research aerodynamics as research parachute, area of contact in order to change with air, by area of contact and then calculating resistance of air size, and need to consider the ratio of density and the air density of object moving, in the time that the density of object moving and the ratio of air density are 1, object moving can be suspended in air, such as hydrogen balloon fire balloon etc. (this be less than when the low latitude 1 just up), but solid object is far longer than 600 times to up to ten thousand times of air density, such as the density of water is 1, air is 1.29 kilograms/m3, the density of water is approximately 775 times of air density, iron and steel is 6000 times of air density, when the object of different densities is different from the area of contact of air, the kinetic characteristic of performance is different.Area of contact is less, and when the movement of falling object, the conversion ratio of kinetic energy can be higher.This is that the moving object speed of freely landing is faster, faster with the striking speed of air molecule because constantly collide with air molecule in object of which movement, and air molecule movement velocity will faster (air particle acceleration be larger); The reaction force of the air molecule that freely falling body object moving obtains is that resistance will be larger, the kinetic energy consuming in its landing or running is just larger, therefore the resistance of air is relevant with two technical orders, and the 1st, the area of contact of object moving and air, the 2nd, the motion speed of object moving.Wherein resistance of air is directly proportional to the area of contact of object moving, to square being directly proportional of object moving speed.In other words, the object moving in air moves vertically downward or parallel ground motion all exists power consumption, its power consumption (being suffered resistance) has been converted on " kinetic energy " of direct contact or mediate contact air, therefore must consider this " kinetic energy " value number, there is new problem in this but " kinetic energy ", new problem is exactly the half (MV2/2) that kinetic energy equals the product of its quality and its velocity squared, speed is a relative velocity, and this speed must be using large ground level as reference system in the explanation of our traditional energy, to observe law of conservation of energy, must select unified reference system, we are at present all refers to plane (or claiming the earth) relative to the earth to the explanation of energy.Here just involve an inevitable factor, the jet velocity of the jet-powered car (or other aircraft) that we say conventionally, instant because jet, must be relative automobile (or other aircraft), and energy conservation calculating needs the relative earth, two speed are not same reference systems, therefore while calculating as energy, must be converted to same reference system, so just had, although the jet velocity of automobile is very high, but during with the motion speed opposite sign but equal magnitude of automobile, speed is relative to the earth just zero, and its kinetic energy is just zero.Does is but for automobile, the kinetic energy of gas jet how many? for automobile, its jet velocity has kinetic energy at full speed at the moment.In other words, although energy is a scalar, but the number of energy must be for certain concrete metastable reference system, the number and the numerical value that are exactly energy have certain relativity, when reference system has been determined, its energy values just can be determined, just can meet law of conservation of energy under same reference system.
According to above energy relative theory and law of conservation of energy, the energy unnecessary consumption that the applicant proposes jet-powered car be directly proportional to (V2-V1) 2 sizes (wherein V2 is the velocity amplitude with respect to the jet gas of automobile, and V1 is the instantaneous velocity value of jet-powered car).The idle work that is jet-propelled power is directly proportional to (V2-V1) 2.This law is not only suitable for jet-powered car, is applicable to equally all reaction power plants such as rocket, guided missile, aircraft and jet train, steamer, submarine.
Cause jet-powered car starting, Accelerating running be the recoil active force of jet-propelled gas to automobile, derive from Newton's third law, the size of active force just can cause starting and the acceleration of automobile in the situation that being greater than resistance.Therefore whether energy-conservation, will study in actual applications the motor-driven and exercise performance of automobile, the reckoning of jet active force is the first element, and its significance is much larger than the reckoning to jet velocity, but just must consider jet velocity for after operation.In common out-of-control situation, jet velocity can be higher, at patent application " pressure slow releasing apparatus of pressurized air jet-powered car " application number: the pressure slow releasing apparatus in 2012102111777 strengthening active force area, reduce pressure, increase aspect Security and play a role, objectively jet velocity is had to abated effect.Cause energy-conservation or velocity amplitude how not change less than description according to the speed of a motor vehicle but whether the velocity amplitude difference that weakens how many and jet velocity and automobile is close to zero, for how energy-conservation and energy-conservation amplitude does not relate to, structure is also had any different, and the technical problem solving from the application is actually different.As mentioned above, what the application solved is that the Conversion of Energy of realizing jet-powered car maximizes, and is a kind of a kind of concrete grammar that improves jet-powered car efficiency.
The dynamic index of jet-powered car and energy-saving index: 1, jet thrust: having thrust in the technical order of aircraft is how many these technical orders of ton.On orthodox car, replace with " moment of torsion " this word.Reason is the conversion that automobile needs power between wheel and various gear, see that rotating of wheel has the process of an engine positive power and negative work for one week, when acceleration, positive work is greater than negative work, while thering is no fuel, negative work is greater than positive work, therefore, in the automotive wheel epoch, " moment of torsion " this word is inevitably, and the conversion of the mutual power of gear and the comparison of all kinds of garage engine performance be convenient in this word of moment of torsion.Because aircraft operates in linear state, and have a maximum jet thrust, therefore the power performance of aircraft represents with " thrust ".And jet-powered car should with " moment of torsion " technical order comparison of automobile, with the direct Thrust comparison of aircraft, therefore must have a unified technical order to contrast again.With respect to piston engine automobile, jet-powered car jet thrust has more continuity, therefore can obtain rapidly high-speed, but automobile not necessarily needs so high-speed, therefore to there be one or more jet valves, one or more levels control system control jet thrust size and interrupt its continuity when jet in other words.In other words: power has instantaneity, power has action time.In cyclic process of motor, only has a stroke in acting, such as only having expansion stroke to do positive work to automobilism in 4 strokes, although the time of three times of the stroke cost of its excess-three, expansion stroke, but do not do useful work, in other words the most of the time of motor in operation process do not do work, only maintain a kind of working state, and jet-powered car is just different, jetly just can think that jet is continuous as long as have, therefore for same " power ", the action time of the power of jet-powered car will be grown.It is large that the momentum that automobile obtains is wanted, and speed promotes wants fast, be exactly acceleration be continuous, and the acceleration of moment of torsion automobile is intermittent, motor also can produce intermittent vibrations sound thus, and from this respect, jet-powered car contrasts as the technical order can not find with orthodox car.Actually this is not so, can be relatively except maximum force, more can compare be the output of same maximum moment time output power, in the situation that moment is onesize, power is different, therefore unified technical order is exactly the output power under output power and equal moment.
Thrust is calculated: the product of jet area and pressure is exactly thrust, and pressure is commonly referred to as " pressure ", is in fact the pressure of unit area, is 20MN such as 20MP refers to the pressure bearing on 1 square metre, i.e. 20 meganewtons.If opening is 1 square metre, pressure is 20M newton, be equivalent to 2000 tons of thrusts, such thrust is too large, be not suitable for the object moving that the quality such as automobile are less and resistance is less, therefore need to reduce jet bore, 1 square centimeter equal 1 square metre ten thousand/, therefore in the time of 20MP, 1 square centimeter backward the jet reaction force obtaining be 200 kilograms, the thrust of 200 kilograms can make the automobile of heavily approximately 10 tons start gradually substantially, but be equally the thrust propelling vehicle of 200 kilograms, due to active area difference, pressure difference is too large, pressure produces reaction force and easily hurts people when too large, and produce kinetic energy consumption, therefore, the thrust increased area of 200 kilograms outwards need to be discharged or carry out resistance and hinder backward outer release, it is 2 square metres such as changing release area into, compressive load per unit area just becomes 0.01 kilogram every square centimeter so, almost hinder less than people.Also can impact automobile below hardly, will greatly take on a new look for the Safety performance of jet-powered car; In the situation that acting surface pressure reduces, the active force that the air of certain mass is subject to can reduce simultaneously, and jet velocity can reduce, and is beneficial to energy-conservation.Increase in addition resistance area, resistance area carries out the effect of power to back air, and resistance becomes automobile onward impulse.
Product=M2V2 of the action time of jet velocity: draw according to momentum conservation law: thrust F and power, the action time of power is relevant with the pressure of pressurized gas, relevant with the pipeline length of gas jet process.Can do liken with one section of spring: for elasticity or the certain different power of gas exerts of viscosity, as spring larger action time of power longer, duct length is as the length of spring, the longer spring motion of spring is faster.Therefore, for reduce gas movement velocity should reduce the length of jet pipe as far as possible.
Summary of the invention

Accompanying drawing explanation
Fig. 1 is the jet deceleration power engine of jet-powered car side view.Fig. 2 is the side view after jet deceleration power engine is opened.Wherein 1 is drag power face, 2 is rotating shaft or rotary connecting device, 3 for power valve be jet opening or the jet opening place that is relatively tightly connected, 4 is the mobile belt that is tightly connected, 5 is the second forbay internal resistance face, and 6 is the second forbay, and 7 is the gas jet resistance area of the first forbay, 8 is the switch valve of the first forbay, and 9 is the first forbay interface.(note: the first forbay is pressure energy-storage tank, does not represent in the drawings).
Embodiment
The similar motor of jet deceleration power engine, play equally the power output function of motor, but slightly distinguish with " starting " two words, because generally unlike motor certain need ignition start or utilize starter motor turn round in advance come " starting ", but directly start by electromagnetic valve or electric installation snap switch valve, do not start difficult problem, therefore have more the function of " power " from name, rather than as " motor ", exist repeatedly start or flame-out may, therefore be called " power engine " and be not " motor ".
The primary parameter of power engine operation is exactly forward thrust, and thrust is greater than automobile resistance (comprising making a concerted effort of frictional ground force, automobile gravity component, resistance of air) automobile and just may moves.Wherein the resistance of automobile is variable under different situations, and frictional force equals the product of vehicle weight and friction factor, and because carrying capacity changes, automotive friction power can great changes have taken place.Partical gravity when automobile up slope or descending is to automobile front driving or retreat component is provided, and the automotive performance of design is such as grade ability should count slope change.Resistance of air comprises with surface of contact, air density, car shaped, the car speed of air to be taken into account.Require to design different maximum thrusts and variable thrust according to the power performance of automobile and speed ability, and further consider the energy-conservation demand under different situations.Such as the car of heavily approximately 1 ton when unloaded the thrust of 20 kgfs just can on level road, travel, therefore, can be designed into 200 kilograms-1000 kilograms for the Automobile Maximum thrust of approximately 1 ton of weight, 1000 kilograms of above thrusts can allow the automobile of heavily approximately 1 ton as helicopter, carry out 90 ° of climbings.But this is super power consumption, just as aircraft, consume energy, under general status, only design common running state increases the mobility of automobile under energy-conservation situation, such as startup is fast, it is fast to accelerate, motion speed is fast, and when motion speed is fast, accomplish energy-conservationly, this is not easy to accomplish.Consumed energy is different under friction speed, therefore more whether the distance of the vehicle running distance of same weight can not energy-conservation, whether energy-conservation or show that maximum effect is within the same time, to move identical distance whether energy-conservationly could show, except also have velocity ratio apart from relatively, under same speed, move same distance, could compare energy consumption how many, could more energy-conservation.
The design of this power engine is to infer and the jet velocity of jet-powered car and the difference of automobilism speed is less according to law of conservation of energy and energy principle of relativity, more be beneficial to energy-conservation, therefore this power engine, for the situation of automobile low speed and stall, reduces jet velocity and realizes energy-conservation in the situation that not reducing power size.
Below with reference to the accompanying drawings 1 and accompanying drawing 2 introduce embodiment.
In Fig. 1, show the state that the jet opening of the second forbay is not opened, and Fig. 2 shows the state that the jet opening of the second forbay has been opened.Fig. 1 and Fig. 2 do not have other differences.In figure, show be the second forbay all and fixture, comprise gas inlet and gas outlet, the first forbay gas outlet is exactly the second forbay gas inlet, comprise the gas jet resistance area (7) of the first forbay, the switch valve (8) of the first forbay, the first forbay interface (9).Described the first forbay is exactly gas holder, and no matter pressure gas tank has how many, and what kind of pressure has change, and how to connect each other, as long as energy storage use and directly in the face of extraneous gas jet is generally called the first forbay exactly.As long as cause changing direction or change discharge time or change pressure and can form relative seal case under certain pressure and there is resistance area to hinder the first forbay gas jet, no matter this casing has how many, how to connect each other, be all referred to as the second forbay.In other words the difference of the first forbay and the second forbay is only distinguished from function, and acting is the second forbay to external world, no matter how how size has how many to geometric figure.Directly acting is not only energy storage or what carry out pressure conversion is exactly the first forbay to external world, and such classification can simplify a problem.The first forbay must connect the second forbay, in Fig. 1 and Fig. 2, connection set comprises the gas jet resistance area (7) of the first forbay, the switch valve (8) of the first forbay, the first forbay interface (9), wherein the gas jet resistance area (7) of the first forbay is deep into the second forbay inside, and resistance area approaches the second forbay inwall, thereby object is to reduce distance to reduce kinetic energy rejection, gas jet resistance area (7) size shape and the gas outlet various ways of the first forbay, as long as slowly release the first forbay pressure is just passable to play gentle change the first forbay gas jet direction.It is the mechanical change device between the first and second forbays, therefore there is good mechanical property, between the first forbay and the second forbay and automobile, there is extraordinary mechanics connection set, because do not show in the accompanying drawings that in order to simplify accompanying drawing the gas jet resistance area (7) of the first forbay is connected with the physical support structure of the first forbay, do not show the mechanical structure that is connected with automobile yet, do not show the stressed linkage structure of mechanics of the first concrete forbay and the second forbay yet, but common mechanical teacher can easily design the mechanical structure of connection according to the stressed size of the first forbay and the second forbay, these structures only play strength and stable effect, because act on the mechanical structure of automobile by reaction force always, each tie point needs stable and can bear maximum reaction force.Because this part is irrelevant with present techniques scheme, do not state therefore save.
The gas jet resistance area (7) of the first forbay stops that after the switch valve (8) of the first forbay is opened gas jet makes it directly to obtain backward power from the first forbay ejection gas, but volume expands under the effect of the second forbay (6) inwall, backward inegration after pressure disperses, ascending gradually in the second forbay internal pressure, arrive after certain pressure, promote two forbay internal resistance faces (5), make jet opening or jet opening be relatively tightly connected place (3) open, gas ejection, produce reaction force, drive drag power face (1) to move backward simultaneously, because drag power face (1) is that larger area is tabular, be subject to Air Reverse active force, make automobile the same as gas jet obtains the active force that moves ahead, because its border movement speed approaches gas jet speed, pressure is almost equal at grade before jet opening (3) is opened for the internal pressure that is to say the second forbay, therefore gas jet and dynamic drag face (1) obtain reaction force simultaneously, reaction force thereby larger, but gas jet speed is less, thereby reduce the consumption of gas jet kinetic energy.
In Fig. 1, drag power face (1) is an inclined-plane (there is no vertical ground), object is that the action direction of the gas to effect after jet opening (3) is opened is backward rather than is dispersed to other directions, reduces the consumption of active force, and then reduces energy consumption.In order to show this effect, can be as can be seen from Figure 2, vertical ground of dynamic drag face (1) after jet opening (3) is opened, if must cause drag power face (1) again to become an inclined-plane but strengthen again on this basis power, as long as outwards just there is kinetic energy rejection on inclined-plane, but as long as inclined-plane is inside, due to the interaction of upper lower inclined plane, it is made a concerted effort still backward, therefore general design resistance power face (1) is upper and lower symplex structure or symmetrical structure or circle or polygonal symmetry or approaches symplex structure, symplex structure forms dynamical balancing after can making inclined-plane comprehensive.But what in Fig. 1 and Fig. 2, show is only upper and lower dissymmetrical structure, top is greatly below little, object is that drag power mask has resetting means, when the second forbay does not have pressure, drag power face (1) can select to return to reset condition, can use spring tension resetting means or other resetting means, and Fig. 1 and Fig. 2 demonstration is gravity reduction device, the top that is drag power face (1) can reset naturally due to gravity reason, bottom can adopt other pulling force resetting means, therefore be designed to upper and lower asymmetric mode, this mode does not immobilize, but freely design according to beautiful shape and mechanical characteristics.
Jet opening (3) shows sealing relatively in Fig. 1, can bear certain pressure in the second forbay, locating to select to design upper and lower paster mode at jet opening (3) seals, gravity or elastic force more closely stick together the two, gravity or elastic force also can not be too large, and the mechanics that only makes the two be close in the satisfied design of relative sealing requires just can achieve the goal.Concrete data will design according to power size and power of vehicle size.
Because the second forbay drag power face (1) need to act on ambient atmos, therefore need rotatingshaft (2), or only have several run-on points, as long as can guarantee that drag power face (1) moves backward and easily reset, rotate, frictional force is little, is general knowledge.Simultaneously, the second forbay (6) need to seal relatively, need certain pressure tolerance, therefore the rotatingshaft of drag power face (1) needs to increase the mobile belt (4) that is tightly connected cannot realize under the prerequisite separating with the second forbay (6) physics, material can be the metal tape with gauffer, can be in the scope requiring movable, can be also the sealing material that other toughness are stronger, such as macromolecular materials such as plastic, rubbers etc.As long as adapt to external environment and internal stress and there is light activity effect.
The second forbay (6) has certain volume, but longitudinal separation is that the distance between the second forbay internal resistance face (5) and the gas jet resistance area (7) of the first forbay is not too big, ratio in Fig. 1 and Fig. 2 demonstration is slightly larger, be only used to show that the second forbay has certain volume, if this distance is too little, must cause volume too little, distance must cause gas in the second forbay, to produce gas motion speed too greatly again, produce larger in-fighting, therefore the setting of this distance and volume will have above-mentioned two tendentiousness, can not cannot accomplish too greatly again too little, as long as but can accomplish distance little still tend to do little.It is exactly drag power face (1) that the second forbay (6) also has very crucial power plant, be divided in the drawings upper and lower two-part, two-part can symmetry also can be asymmetric, this drag power face (1) can be from (3) opening that is tightly connected under the effect of the second forbay (6) pressure, therefore in figure, the expression to reference character is " jet opening or jet opening are relatively tightly connected place ", the meaning is " place is relatively tightly connected " exactly in Fig. 1, in Fig. 2, represent " jet opening ", although be same position, but mouth is jet backward thus in the time of work, therefore accompanying drawing is marked the price (3) be defined as gas opening or the jet opening place that is relatively tightly connected.
Can increase multistage pressure slowing device and make jet velocity be reduced to minimum in the second forbay in order to reduce jet velocity, can accomplish by increasing gas orbit resistance area, in forbay, increase exactly repeatedly resistance area, on the orbit of gas, increase resistance area, gas jet resistance area (7) device of similar the first forbay, can make structure complicated cost increase but do so simultaneously, this can only need to arrange according to the pressure of the first forbay, because principle is identical with above-mentioned narration, be not described in detail here.
What Fig. 1 and Fig. 2 showed is side view, so only shown the main structure part of the jet deceleration power engine of jet-powered car, its width is not represented, it is contemplated that the rear facial planes of automobile, can be designed to meet the drag power face (1) of mechanical characteristics shape, its width is generally less than the width of automobile, but only have large as far as possible guarantee drag power face (1) to there is larger area, consider that from mechanics resistance of air generally becomes unrealistic but exceed automobile rear area, certainly do not get rid of under the few cases structure is become to large.Meanwhile, the design of the shape of the gas jet resistance area (7) of the first forbay will meet the shape of the second forbay internal resistance face (5), makes every effort to the gas pressure that the second forbay internal resistance face (5) is subject to even.If not so, gas movement locus in the second forbay (6) is changeable, increases in-fighting.The extreme situation that increases in-fighting is exactly to remove gas jet resistance area (7) device of the first forbay, high-speed gas still can be washed the second forbay internal resistance face (5) open, but gas motion track is indefinite, increase in-fighting, therefore the design of the gas jet resistance area (7) of the first forbay need to design according to the shape of resistance area (5) in the second forbay (6), gas motion direction is distributed more even, in the second forbay (6), resistance area (5) is stressed more even.
