Description
The present invention relates to a kind of by liquid fuel (oil) container, oil outlet, flexible pipe, the broad-spectrum aerospace flight vehicles such as civil aircraft, military fighter aircraft, guided missile, spacecraft, carrier rocket, space shuttle, submarine, torpedo that flyball, band pressure compress composition such as fire-retardant gas or air intlet fly all the flyball fuel tank of fuel feeding (also being the flyball liquid fuel tank) for a long time in any case, abbreviation flyball fuel tank.
In the present prior art, as the homemade fighter plane F-7MG of China " Aug. 1st " aerobatics team machine, this bird dog is on " aviation knowledge " 1999 the 1st phases the 11st page of left hurdle, put down in writing the defective of this fuel tanker from several the third lines of staying, " because the restriction of fuel tank design-calculated, the inverted flight state of this aircraft can not continue more than 15 seconds, otherwise flame-out in flight appears in the meeting oil-break ", owing to have this defective, so influenced this fighter performance.
Task of the present invention is: a kind of simple in structure, cost is low, performance is good flyball fuel tank is provided.No matter aircraft how long just flying, inverted flight how long, acceleration and deceleration how long, suitable conter clockwise roll how long, how long right anti-somersault, how long positive flying disc revolves, and inverted spiral how long, no matter how to fly, whether play reinforcing, flyball fuel tank uninterruptedly fuel feeding is given combustion chamber or afterburning chamber, until liquid fuel (fuel oil) uses until exhausted in the flyball fuel tank.
But flyball fuel tank of the present invention by one can justify can be just the also Fuel Tank of other shape (also can be fuel container) and various fire-retardant, not combustion-supporting, difficult combustion, gas inlet such as flammable air not, its fire-retardant difficulty is fired not, and combustion-supporting gas is mainly used to prevent the blast of Fuel Tank fuel combustion, and give liquid fuel pressurization in the Fuel Tank, so that smooth output liquid fuel.If do not pressurize, will in the flyball fuel tank, form vacuum owing to output liquid fuel, cause output liquid fuel to be subjected to atmospherical drag, be directed at the oil transportation difficulty, and can make Fuel Tank under bar pressure, damage distortion etc. by pressure, so will in the flyball fuel tank, establish a pressure sensor, when recording the decline of flyball tank pressure, automatic guidance gas filled device at once, in the flyball fuel tank, fill fire-retardant not combustion-supporting difficult combustion gas body or mixture gas air, if be pressed into combustion-supporting gas, fuel and combustion-supporting gas can react after the flyball fuel tank is hit and blast in the Fuel Tank.Fire-retardant gas can be the fire-retardant not combustion-supporting gas of difficult combustion such as carbon dioxide gas, nitrogen, unreactable gas.Arrange an above oil outlet on the flyball tank envelope, in technical solution of the present invention, an above fuel outlet, each fuel outlet is connected with the flexible pipe of various structures, flexible pipe also will have certain elasticity, and smooth in appearance and anti-stubborn kinking, prevents to stop up fuel in pipe, flexible pipe simultaneously can free bend, material: plastics, rubber, composite material and other material.One to two or many flexible pipe other ends are connected with a flyball, and the length of flyball and flexible pipe is so that a corner and any one corner that flyball can reach farthest are standard, longer also can, in particular cases length can be shorter, as civil aircraft.Flyball must have larger specific gravity and big weight, can not do too greatly or too little.The flyball profile can be that the hollow cylinder flyball also can be sphere, square, cuboid or other shape, all need have one on it with upper shed or seam hole, hole, opening, hole seam shape are not limit, general fighter plane is with can not only establishing an opening or seam hole, hole with flyball in the flyball fuel tank, one easily by the flyball oil tank wall stifled on, cause disconnected transfusion fluid fuel or fuel (oil) is not smooth for liquid.Soft and the high resilience of the appearance of flyball, and it is smooth, the flyball appearance that reinforcing flyball fuel tank is used can be hard, so neither can break Fuel Tank, be convenient to again slide, make flyball follow fuel to slide synchronously and roll, that is to say that flyball follows fuel to walk in tank inner wall, and no matter how much surplus liquid fuel is also, flyball is in the liquid fuel (oil) all the time, and the continuous imbibition fluid fuel (oil) of energy, gives driving engine (piston type by flexible pipe to the pump pump of back, the whirlpool spray can be with reinforcing or be with reinforcing, turbofan becomes circulation with or without reinforcing, punching press, rocket and the jet-propelled boost engine of being with of combination, and whirlpool axle, submarine, the torpedo driving engine), make its uninterrupted fuel feeding.The flyball structure can be divided into bilayer or multiple-structure and single layer structure, double-deck internal layer is heavier or heavy metal or alloy and other metal and non-metallic material, and the preferably high and high resilience of these strength of materials is not yielding, outer plastic covering or rubber, the composite material pasted.The individual layer flyball can be metal and alloy and other metal or non-metallic materials such as steel, also can be elastic caoutchouc and plastics.In order to increase the weight of flyball, can in rubber, plastics, add heavy metal particles dusty material or other heavy non-metallic particle dusty material.Because the liquid fuel suffered inertia of flyball in flyball fuel tank (liquid fuel tank) and in the flyball fuel tank, gravity, the resultant direction of various power such as centnifugal force is identical, also identical to the time that their generations are made a concerted effort, so flyball follows liquid fuel with running on foot or being still in the same area in the flyball fuel tank, and be immersed in the liquid fuel all the time, no matter how much surplus liquid fuel is also, be not subjected to it to influence imbibition fluid fuel (oil) yet, thereby no matter how aircraft flies, how motor-driven the submarine torpedo is, flyball always can be drawn onto liquid fuel, and not cut-off liquid fuel (oil) is given the driving engine of aircraft.
Owing to adopted one or more one to two of connecting as one side by side or many flexible pipes and one and flexible pipe bonded assembly flyball imbibition fluid fuel (or propellant) in this flyball fuel tank (Fuel Tank), thereby be not subjected to various attitudes of aerospace flight vehicle and the motor-driven various power that produce that oil level is changed and the influence of motion and fuel feeding smoothly, because flyball is followed all the time or is immersed in the liquid fuel, so no matter how aerospace flight vehicle flies, how long constant various flight attitudes are, as long as in the flyball fuel tank liquid fuel is arranged, flyball just can be drawn onto liquid fuel, can interrupt delivery liquid fuel (oil).

In optimum implementation of the present invention, preferably only with a smooth surface, heavier whippy flyball 6.With flyball 6 bonded assembly flexible pipes 5 (fuel supply pipe) preferably only with one, flexible pipe 5 also should have a suitable less elasticity, the length that flexible pipe 5 and flyball 6 are added up must be able to make flyball get at farthest a corner (longer also fine), and admission port 7 is preferably only established one.As long as fuel inlet 8 is preferably one and be contained in flyball fuel tank 1 top, pressurization burn-proof and explosion prevention gas preferably selects the air that burnt in the liquid fuel tank, it is easy to get air-capacitor like this, fire-retardant gas feed 7 is located at flyball fuel tank top, shell 1 is preferably and seals cylindrical shape, one be located at behind the flyball fuel tank 1 and go out liquid fuel (oil) mouthful 3, one pressure sensors with the flexible pipe bonded assembly and be located at flyball fuel tank top.In a word, optimum implementation can be under the situation of not sacrificing good oil suction (fuel) performance, and it is simple in structure that whole flyball fuel tank (Fuel Tank) is had, and is convenient to maintenance, and in light weight, cost is low, helps advantages such as flight.
This flyball fuel tank is work like this: at first add to flyball fuel tank 1 by liquid fuel filler opening 8 and fill with liquid fuel 4, liquid fuel filler opening 8 is discharged the gas in the flyball fuel tank in fueling, when liquid fuel constantly spend vacuum appears and after, the flyball tank pressure reduces, at this moment after the pressure sensor (not shown) measures, automatic guidance inflation mechanism (not shown) is filled fire-retardant gas in flyball fuel tank 1, fire-retardant gas just is pressed in the flyball fuel tank by import 7, after flyball fuel tank 1 internal pressure reaches predetermined value, sensor is controlled inflation mechanism again and is stopped inflation, the fire-retardant gas that charges at flyball fuel tank 1 by the weapon bullet, shell fragment hits back discord liquid fuel reaction, stops combustion explosion takes place.When aircraft is at the uniform velocity flat forward when flying flyball since terrestrial gravitation attract to be in bottom the fuel tank, and liquid fuel is attracted by terrestrial gravitation too simultaneously and is in bottom the fuel tank, like this, flyball is fuel feeding with regard to being immersed in the flyball fuel tank bottom liquid fuel and constantly, how long no matter this posture prolong, as long as liquid fuel is arranged, flyball just can be drawn onto liquid fuel and fuel (oil) is continuous for liquid.
As shown in Figure 4, aircraft 1, flyball fuel tank 2, flexible pipe outlet connector 3, flyball 4, liquid fuel position 5, flexible pipe 6, fire-retardant gas or air 7.This figure has represented that aircraft 1 is at the uniform velocity just flat and has flown the position of liquid fuel 5 and flyball 4.
When aircraft to preacceleration just or when falling flat flying, liquid fuel in the flyball fuel tank can move backward owing to action of inertia, flyball is moved by action of inertia and liquid fuel also can synchronously backward, do not stop if quicken, liquid fuel and flyball will stationary fixing at the rear portion of flyball fuel tank, flyball just can soak on the go or stationary fixing in the liquid fuel at rear portion when preacceleration is constant like this, just can constantly suck fuel, till liquid fuel exhausts.
As shown in Figure 5, aircraft 1, flyball fuel tank 2, flexible pipe outlet connector 3, flyball 4, liquid fuel position 5, flexible pipe 6, fire-retardant gas or fire-retardant air space 7, this Fig. 5 are showing aircraft 1 just or the acceleration of falling the (not shown) is flat forward flies the position at liquid fuel 5 and flyball 4 places.
When aircraft just or fall flatly to fly to slow down and when constant, the liquid fuel in the flyball fuel tank will be under action of inertia to the flyball fuel tank anterior move or stationary fixing in the fuel tank front portion.The flyball band flexible pipe, and also can to stretch to the flyball fuel tank under action of inertia synchronously anterior and be immersed in the liquid fuel all the time, and can constantly suct liquid fuel and non-interrupt delivery liquid fuel.
As shown in Figure 6, aircraft 1, flyball fuel tank 2, flexible pipe outlet connector 3, the flyball 4 that joins with flexible pipe, liquid fuel 5, flexible pipe 6, fire-retardant gas or air space 7 can find out among Fig. 6 that aircraft 1 is just or flat flyball 4 and the liquid fuel 5 residing positions as can be seen of flying of the deceleration of falling the (not shown), in flyball 4 liquid fuel withins 5, obviously flyball can be drawn onto liquid fuel.
When at the uniform velocity level inverted of aircraft, the aircraft back down, liquid fuel and flyball in the flyball fuel tank are subjected to downward action of gravity simultaneously, flyball and liquid fuel will be poured into the back simultaneously in the same way, state of flight is constant, and the liquid fuel and the flyball position that are in the flyball fuel tank back in the aircraft just remain unchanged, and flyball is in the liquid fuel all the time, and can be drawn onto liquid fuel, till liquid fuel sucks.
As shown in Figure 7, aircraft 1, flyball fuel tank 2, flexible pipe outlet connector 3, flyball 4, liquid fuel 5, flexible pipe 6, fire-retardant gas or the air space 7 of conveying liquid fuel.This illustrates, and aircraft 1 is at the uniform velocity flat to fly, flyball 4 and liquid fuel 5 residing position in the flyball fuel tank, and as can be seen from the figure flyball 4 is immersed in the liquid fuel 5 at flyball fuel tank back, can constantly be drawn onto liquid fuel (fuel oil).
When aircraft flies upside down, liquid fuel and flyball in the flyball fuel tank have four kinds of situations: first kind of situation, acceleration/accel is greater than 9.8 (9.8 is acceleration due to gravity), liquid fuel in the described flyball fuel tank and flyball all move backward and finally are in the rear portion, and flyball also is immersed in the liquid fuel and can be drawn onto liquid fuel; Second kind of situation, acceleration/accel equals 9.8 (acceleration due to gravitys), flyball and liquid fuel are in state of weightlessness, if at this moment give centnifugal force of liquid fuel, flyball and liquid fuel will be attached to periphery jointly under action of centrifugal force, and flyball just can be drawn onto liquid fuel, and the supply liquid fuel is continuous; The third situation, aircraft acceleration/accel are less than 9.8 (decelerations), and then liquid fuel in the flyball fuel tank and flyball just all travel forward, and also termination is at front end, and flyball is immersed in the liquid fuel, and flyball just can constantly be drawn onto liquid fuel, till sucking.The 4th kind of situation, aircraft at the uniform velocity descend upside down, and flyball and liquid fuel are in the front end of flyball fuel tank under the effect of gravity, and flyball is immersed in the liquid fuel, can uninterruptedly be drawn onto liquid fuel, till liquid fuel sucks.
As shown in Figure 8, aircraft 1, flyball fuel tank 2, the flexible pipe outlet connector 3 of output liquid fuel, flyball 4, liquid fuel 5, flexible pipe 6, fire-retardant gas or air space 7.This figure show aircraft 1 descend upside down, at the uniform velocity or acceleration/accel less than under 9.8 the state, their residing positions when flyball 4 and liquid fuel 5 are static in the flyball fuel tank, flyball falls into the liquid fuel of flyball fuel tank front portion, flyball is imbibition fluid fuel (oil) constantly, fuel (oil) is continuous for liquid, till liquid fuel has been smoked.
When aircraft head-up flies, flyball and three kinds of situations of the stressed branch of liquid fuel in the flyball fuel tank: first kind of situation, aircraft upwards quickens flight, at this moment, flyball and liquid fuel all can make liquid fuel and flyball move to flyball fuel tank rear portion because of the inertia backward of gravity and acceleration/accel generation in what position, the power that gravity and acceleration/accel produce does not disappear, flyball and liquid fuel will stop at the rear portion, and flyball will be immersed in the liquid fuel, can be drawn onto fuel all the time.Second kind of situation, aircraft head-up flies to slow down, at this moment liquid fuel and flyball are subjected to inertia upwards and swarm flyball fuel tank top, slow down and do not stop, liquid fuel and flyball will be in flyball fuel tank top and fixed position, and the flyball in the flyball fuel tank just can constantly be drawn onto surrounding liquid fuel and constantly supply liquid fuel like this.The third situation, aircraft head-up at the uniform velocity upwards flies, liquid fuel and flyball in the flyball fuel tank are subjected to gravitating, no matter at the flyball fuel tank where liquid fuel and flyball reference position, they all can gush to flyball fuel tank rear portion (bottom), and the aircraft flight state is constant, the liquid fuel and the flyball position that are in flyball fuel tank rear portion can not become yet, flyball is immersed in the liquid fuel all the time, and can constantly be drawn onto liquid fuel, and the supply liquid fuel is continuous.
As shown in Figure 9, aircraft 1, flyball fuel tank 2, liquid fuel flexible pipe delivery port joint 3, flyball 4, liquid fuel 5, flexible pipe 6, fire-retardant gas or the air space 7 of suction output liquid fuel.This Fig. 9 has represented that aircraft 1 upwards at the uniform velocity or the curved shape of the flexible pipe 6 in the flyball fuel tank that quickens to fly and flyball 4 and liquid fuel 5 residing position when static, flyball 4 is immersed in the liquid fuel 5, and flyball can constantly be drawn onto liquid fuel and to supply liquid fuel continuous.
When the aircraft level flies at a constant speed and roll, in two kinds of situation: to be centnifugal force produce friction force making a concerted effort less than gravity and force of inertia to the flyball in the flyball fuel tank and liquid fuel and flyball inner wall of oil tank to a kind of situation, flyball in the flyball fuel tank and liquid fuel will flow to bottom synchronously with the resultant direction that force of inertia and gravity produce, moving flyball just is in the fuel of motion in the flyball fuel tank, just liquid fuel be can constantly be drawn onto, piston engine jet engine or various other kind driving engines do not given and can not interrupt for liquid fuel.To be that aircraft is at the uniform velocity flat fly and roll for second kind of situation, its centnifugal force is enough big, friction force between flyball and the flyball inner wall of oil tank is enough to overcome the suffered gravity of flyball and liquid fuel and the effect of force of inertia, flyball will adhere to (the flyball fuel tank shells of cuboid, square or other band corner angle) on fuel tank one side inwall or the corner angle, or wherein goes up (do not comprise on the two ends, remove on the edge) attached to the inwall of cylindrical shape flyball fuel tank.
Liquid fuel is suffered to be subjected to resultant direction identical with the time with flyball with joint efforts, so liquid fuel and flyball are in position together, as flyball inner wall of oil tank (cylindrical shape flyball fuel tank) or be in mutually on certain corner or the inwall and (corner angle flyball fuel tank arranged), and flyball can constantly be drawn onto surrounding liquid fuel, and constantly supply liquid fuel (comprising fuel oil), to till suck.
As shown in figure 10, aircraft 1, flyball fuel tank 2, liquid fuel delivery hose outlet 3, flyball 4, liquid fuel 6, flexible pipe 6, fire-retardant gas 7 the figure shows out flat also roll, the liquid fuel 6 in the flyball fuel tank and the position of flyball 4 of flying of aircraft average rate.As seen flyball is mixed in the fuel all the time, and can constantly be drawn onto liquid fuel.
Figure 11 represents flyball 1 structure, and flyball 1 structure is the cylindrical shape hollow shell, and housing can thickly approach.Having the hole open seam 2 more than 1 of imbibition fluid fuel on columnar front and the cylinder, for flyball being connected with flexible pipe and connecting, be provided with a lock-on connection, available various locking method lockings.
Figure 12 represents the hollow flyball 1 of square, 1 above imbibition fluid fuel hole open seam 2,1 lock-on connection 3, the interior conduit of joint 3 makes that flyball is hollow to communicate with the flexible pipe interior conduit, the convex concave flexible pipe 4 that joins with joint 3, flexible pipe 4 other ends and flyball fuel tank output liquid fuel port (bundle draws) are connected.
Figure 13 represents the hollow flyball 1 of spherosome, and 2,1 lock-on connections 3 of 1 above liquid fuel inlet (hole open seam) are arranged on the flyball.
Figure 14 represents the thick hollow flyball 1 of cylinder, 2,1 lock-on connections 3 in a lot of holes (hole open seam).
More than 4 kinds of flyball structures just represent 4 examples, its flyball structure can also be other shape.As ellipse, equilateral polygon cylinder, different shape fabricate block etc., but principle is all the same, and the imbibition fluid fuel hole shape of flyball 1 is not limit, and is best more than four, there are one or two holes to be stopped up like this, also have end, an above hole to be blocked and can the feed liquor fluid fuel by the flyball inner wall of oil tank.By the flexible pipe that the flyball hollow hole sucks and hollow section communicates, the liquid fuel delivery port uses to supply engine liquid fuel earlier.
Military, civilian no augmented jet engine aircraft is only distributed to one or more driving engines (a plurality of piston engines with a flexible pipe and a flyball handle from the liquid fuel of flyball sucking-off with the flyball fuel tank outside the flyball fuel tank, turbofan, punching press, the turbine punching press, the whirlpool spray, whirlpool axle＜helicopter〉whirlpool oar liquid fuel motor, the guided missile rocket engine.Guided missile is with various jet engines and rocket engine).Each driving engine also can special-purpose flexible pipe of a cover and a flyball fabricate block and an oil outlet.1 above flyball fabricate block of cover and oil outlet, supply liquid fuel are given no boost engine use more than.One is one and with an identical flyball suction and pumping liquid fuel that goes out liquid fuel (fuel-displaced) mouthful and be attached thereto common use with the flexible pipe number with top hose and flexible pipe bundle, no augmented jet engine of each flexible pipe connection wherein, and supply liquid fuel.Be with afterburning various separate unit jet engine, can use single flexible pipe bonded assembly solo flight hammer, behind the liquid fuel output flyball fuel-tank outlet that flyball is inhaled, be divided into two strands again, one is communicated with the combustion chamber liquid fuel nozzle, another burst connection afterburner liquid fuel nozzle also can use a flexible pipe and a flyball liquid fuel within that is attached thereto to be sucked out outside the fuel-tank outlet, liquid fuel is distributed to the combustion chamber liquid fuel nozzle and the afterburner liquid fuel nozzle of a plurality of jet engines again.Another kind of situation is each jet engine combustion chamber with a flexible pipe and a flyball, afterburner uses a flexible pipe and a flyball, have several driving engines just to have to double the independently flexible pipe and the flyball fabricate block separately of driving engine quantity like this, every of various augmented jet engine also can use two to be the flexible pipe of a bundle and a flyball that is attached thereto separately.Many various also can use twice and driving engine amount quantity and binding (and example is bonding) for the flexible pipe of one with to tie be that a branch of a plurality of flexible pipes are connected a shared flyball and adjacent liquid fuel joint together more than with power-assisted jet engine, each joint has one with upper outlet, the many twices of general export quantity ratio engine platform number, wherein half of flexible pipe sum is each jet engine combustion chamber burner supply liquid fuel.Second half flexible pipe is the supply of jet engine afterburner noz(zle) separately liquid fuel.
