Description

Vacuum-aeronautical vehicle

Affiliated technical field

The present invention is a kind of course of new aircraft of aerospace field.Because use special flight system, it does not need the runway on airport just can be applicable to and to transport huge amounts of material and passenger in smooth land and water surface landing.

Background technology

At present, the basic appearance structure of known aircraft is all from bionics.It imitates the shape of birds, particularly wing to a great extent.Since modern age science and technology progress, we can pass through physics now, thus methods such as aerodynamics and mechanics are re-recognized the theory of flight and are designed more progressive flight apparatus.Traditional fuselage is based on the manned thing of receiving, and guarantees itself and being connected with reliable of wing, empennage simultaneously, and for the installation of system equipment and pipeline pass through provide convenience.Conventional airplane mainly is to consider as supporting body, is target to reduce resistance on aerodynamics.Traditional flight theory makes our present aircraft flight benefit extremely low.The present invention will be a kind of brand new flight theory.

Summary of the invention

The object of the invention is utilized physics exactly, and subjects such as aerodynamics and mechanics are designed a kind of special flight system, can be in smooth land and water surface landing; And can obtain higher speed and voyage with lower energy consumption.

The technical solution adopted in the present invention is exactly that the atmosphere of transferring the whole world is work of the present invention.Make the working medium of engines tail spray move again from specific air flue nozzle discharge in the design-calculated path in advance along us, evict the natural air of its inner chamber from pelvic cavity in no time in conjunction with the distinctive appearance of flying body bathtub construction again and then make pelvic cavity produce vacuum pad, thereby form vacuum effect.Though it can not be hundred-percent vacuum layer.But its along the air-flow velocity of inner wall much larger than our desired 400 meter per seconds.At this moment, be zero according to its air-flow static pressure of Bernoulli's theorem even be negative pressure.And around here the flying body chassis have that expansile atmosphere will be not stingy power be provided and started working for aircraft.The present invention utilizes vacuum and barometric pressure combined action and produces flight usefulness thus.But still following traditional aerodynamic force at last gains knowledge.The expert who has may query: the theoretical basis of this aircraft lift-off is Bernoulli's theorem on earth or vacuumizes theory.I think as speed V ₁P when reaching very large ₁It is negative value.See P ₀=P ₁+ 1/2pV ₁ ²=P ₂+ 1/2pV ₂ ²From macro manifestations promptly from the static pressure to the attractive force.It is vacuum mode.So my judgement at present: it should be an in-depth of Bernoulli's theorem.May still there be experts and scholars to vacuumize phenomenon in suspection.Please see Figure 4, gas is in case will produce an action of centrifugal force that expands outwardly naturally along annularly flow.They will escape pelvic cavity to greatest extent.And their the only way just has only the chamber collar extension.

Want that the words of understanding aircraft must understand some aerodynamics, will understand most important, the most basic law-Bernoulli's theorem earlier as aerodynamics.The illustrated physics meaning of this law is: for the moving fluid of ideal state, under the prerequisite of not considering temperature traverse, flowing velocity is big more, and then static pressure is more little; Flowing velocity is more little, and then static pressure is big more.

A＝p/2·V _A ²S·C _A＝Q·S·C _A

Lift A and kinetic pressure Q are (promptly with density of air p and speed of incoming flow V _ASquare), wing area S and dimensionaless coefficient C _ABe directly proportional C _ARelevant (the C of object geometric relationship that is flow through with air-flow with the angle of attack _ABe lift coefficient).C _A＝2mg/p·V _A ²S

Bernoulli's theorem

P ₀＝P ₁+1/2·pV ₁ ²＝P ₂+1/2·pV ₂ ²

P ₁--the static pressure of I face

P ₂--the static pressure of II face

1/2 * pV ²--dynamic pressure (also claiming ram compression)

The present invention is a discoid disk, and by basin body type flying body, subject impetus cabin and control compartment are formed.Control compartment places upper end, subject impetus cabin to be occupant's passenger cabin, and this cabin is made by the bright specific glass of full impregnated.All driving engines and airborne equipment all are contained in the piggyback pod of epirelief.Piggyback pod is captiveed joint with flying body and is constituted complete power system.Control compartment relies on turning cylinder to connect with piggyback pod.Be piggyback pod and flying body no matter during with which kind of aerial statue flight, passenger cabin can both keep the posture of level unanimity.

The technical solution adopted for the present invention to solve the technical problems is: what it adopted is bathtub construction, big lifting body, circular holohedry profile total arrangement.Its control compartment and piggyback pod all are in the lifting body, aerodynamic configuration and basin shape inner chamber smooth transition, not only succinctly but also compact.The maximum difference of the present invention and known aircraft is to have cancelled traditional fuselage, replaces the flying body of the wingization, utilizes rocket engine or common aero-jet engine work and is evacuated by force in conjunction with the distinctive appearance of the bathtub construction inner chamber with flying body.The present invention has very big 1ift-drag ratio.A kind of built-in motor and big concavity aerofoil profile (bathtub construction) coupling at lifting body produce lift, thrust, form the principle of work of vacuum effect.The swabbing action of built-in motor: 1. quickened the air motion of lifting body upper surface, on having enlarged/and lower surface pressure reduction, can strengthen lift; 2. to the thrust of the air-flow generation of discharging all around to wall; The air-flow of its discharge divides two air flues can produce vacuum pad, thereby forms vacuum effect.Fuselage, the fuselage of the wingization or the all-wing aircraft of alienation that we can be considered as flying body to evolve.

The beneficial effects of the utility model are: vacuum-aeronautical vehicle integrates boundary 1ayer control, vector controlled and vacuumizes technology, and has that low-resistance promotion, power are controlled, the function of vertical takeoff and landing (VTOL).

The specific embodiment

Demonstrate a kind of built-in motor and big concavity aerofoil profile (bathtub construction) coupling of lifting body among Fig. 1, produced lift, thrust, formed the principle of work of vacuum effect.The swabbing action of built-in motor: 1. quickened the air motion of lifting body upper surface, on having enlarged/and lower surface pressure reduction, can strengthen lift; 2. to the thrust of the air-flow generation of discharging all around to wall; The air-flow of its discharge divides two air flues, and (the air flue nozzle e referring among Fig. 6 and Fig. 1 f) can produce vacuum pad, thereby forms vacuum effect.See Fig. 5, have only the atmosphere in the effective power district making useful work, because the relation of contour structures, atmosphere work done in all the other areas is offset up and down or partial offset falls.Control compartment A relies on turning cylinder to connect with piggyback pod B.Be piggyback pod B and flying body C no matter during with which kind of aerial statue flight, control compartment A can both keep the posture of level unanimity.Please refer to Fig. 2.

What overall (see figure 3) adopted is bathtub construction, big lifting body, circular holohedry profile total arrangement.The engine installation of this aircraft is placed in the piggyback pod in the flying body central authorities, rather than resembles the wing and hang and be exposed to the outside the driving engine, can make the profile of flying body have better streamline contour like this, to reduce aerodynamic drag.Simultaneously, the swabbing effect that engine installation when work produces has enlarged the pressure reduction of flying body, helps to improve lift.Adopting this layout of flush type piggyback pod on the other hand, is to consider other factorses such as engine installation and total are got in touch, power utilization.Intracorporeal space is bigger owing to ascend to heaven, so adopt this layout to be convenient to the maintenance of engine installation too.We can select for use aero-jet engine (subject impetus cabin B) common temporarily, and the size of thrust and jet-stream wind is to control by fuel mass flow rates and jet pipe area by changing the energy of input in time, that is to say.Here we to want ben be that the mounting means of driving engine will be different from conventional jet plane greatly.Slot-shaped nozzle e has been installed, f on the flat section.

We start the aero-engine system.Make the air-flow of engines tail spray move again from air flue nozzle e in the design-calculated path in advance along us, the f discharge, the distinctive appearance of the bathtub construction of flying body inner chamber can promptly be evicted from the natural air in it pelvic cavity by working medium in no time and then make pelvic cavity (referring to the e among Fig. 1, f) produce vacuum pad, thereby form vacuum effect.

In-flight by we can produce moment to the control of balance block P and Q.By means of these moments just can the change of flight device attitude angle.See Fig. 7.We controlled during the flight has only three contents, i.e. P, the position of Q piece and the valve size of nozzle.Wherein the valve size of nozzle can be controlled the power size of flying by let us.The P piece plays the effect of yaw rudder; The Q piece then is control flying body and terrestrial elevation angle 3, and its realistic meaning is that the propelling thrust with atmosphere is decomposed into the horizontal sliding power that the vertical power that overcomes the aircraft self gravitation and driving aircraft move ahead.See Fig. 7 (a).

At this, we only study the control (physical construction and the principle of Q and P are in full accord, and we repeat no more) of P piece.Please referring to Fig. 8, the P piece slides freely along slide rail 1, and 2 is one or two screw rod to rotation, and the one end connects with motor.Motor just, C.C.W. rotates and just can drive screw rod 2, C.C.W. rotates.The P piece is threaded with screw rod 2 again simultaneously.Screw rod 2 just axial, thus C.C.W. rotates and can drive the P piece along the advance and retreat freely elevation angle of slip may command flying body of slide rail 1, because the center of gravity that the P piece slides and objectively regulated flying body freely along slide rail 1.This opens the situation of spiral nail the spitting image of us, and we can become the straight-line motion of spiral nail at rotatablely moving of rotation screw cutter.So we can to motor just pass through fully, C.C.W. rotates the aerial statue of control and then control flying body.

Following our look back again valve size of nozzle.Wherein the valve size of nozzle can be controlled the power size of flying by let us.Under the situation of flying under the low speed, we adopt the flow velocity of the outer jet body of contracting nozzle control of variable area for accidental.It can be at low speed, and part thrust mode of operation is mated between the thrust mode of operation to greatest extent preferably.This class jet pipe can produce bigger base drag when being in inside off position.And the convergent contour iris formula that adopts variable area changes the area of contracting nozzle and just can not produce this base drag.Certainly another method that changes the exit area of contracting nozzle is to adopt movably central plug, and central plug slides backward and just reduces exit area.

Though this flying body is an all-metal construction, use because of wherein there being roomy space to can be used as visitor/cargo hold, so its structural weight and little.Especially the fuselage of the wingization has great unloading effect, and the aerodynamic lift that this point produces for using is offset deadweight, guarantees that good airworthiness seems very necessary.
