Description

Carrier-borne aircraft two-period form pulley blocks ejector

Technical field

It is a kind of to push the piston (2) in cylinder barrel (1) to generate power with high pressure gas, then by two-period form pulley blocks piston (2) high-thrust short-travel is converted into the ejection force for pushing away that power is small and stroke is grown, and even acceleration ejection work is done to adapt to aircraft carrier The power catapult-launching gear of work carries out acceleration ejection with this technology to aircraft carrier.

Background technology

It can see on network：Steam catapult C-13 types are the ejector of aircraft carrier shipboard aircraft that U.S. army uses.It is lacked Point is such as：Because steam cylinder barrel is too long, the long centre of transmission rod can sink, and quality is too heavy, and ejection work can not carry out or efficiency It is extremely low.Breach is greatly enhanced so just being opened from the beginning to the end on cylinder barrel, the power of piston is spread out of from breach to carrier-borne with the shortest distance Machine is launched.This also has prodigious defect, and quickly, the long closed place of mouth has steam leakage, easily grinds for long mouth airtight element abrasion Damage replaces trouble.It is to have enough power when ejection, enough gas pressure intensities, institute will be kept to ejection tail end since ejection High pressure high fever energized gases to enter entire cylinder barrel from high-pressure boiler are substantially that original volume is non-bloating, high pressure after the completion of ejection High fever energized gases just discharge, and capacity usage ratio is extremely low.Because being that the heat dissipation of high pressure superheated steam is inevitable, timing is needed to supplement Thermal energy, when ejection, can waste a large amount of fresh water.Electromagnetical ejector, exporting great electricity electric current in very short time makes conducting wire and electronics Element over-saturation is run, and generates very big heat, to there is pretty troublesome cooling system, to have big-block engine and storage electric energy to set Standby, it is big to occupy space in 200m or so for ejection and buffering route track length.It is required in material and technical aspect and cost is high, Sole mass bigger of the electromagnetic propeller movement parts quality of Electromagnetical ejector than steam.Rocket-assisted ejection, spring ejection, gesture Can ejection, the these types of inadequate natural endowment of combustion gas ejection, not using being just denied.

Invention content

Carrier-borne aircraft two-period form pulley blocks ejector is exactly the parameter of U.S.'s Aircraft carrier steam ejector on reference net, makees a set of cylinder Cylinder (1) piston (2), cylinder barrel (1) tail portion are connected in aircraft carrier steam boiler, so that high steam is may flow into cylinder barrel (1) and push piston (2) it is ejection acting.Piston (2) impulse stroke is the 1/4 of steam catapult piston stroke in cylinder barrel (1), and the cross of cylinder barrel (1) Sectional area (piston forced area) is 4 times of steam catapult cylinder barrel cross sections product, and the two launches the high steam in work Volume is also just equal, and it is also just equal to carry out the work(that ejection is made for two kinds of ejectors when high-pressure steam pressure is equal.Two sections of carrier-borne aircraft Piston (2) thrust of formula pulley blocks ejector is 4 times of steam catapult piston thrust, and impulse stroke is steam catapult 1/4.Two-period form pulley blocks are utilized piston (2) thrust to be reduced into again 1/4 ejection force when launching carrier-borne aircraft, stroke increase is 4 times of ejection travel, and it is converted to the ejection propulsion and ejection travel of original steam ejector, it meets carrier-borne aircraft and is launched The condition of power needed for flying.

The acceleration ejection work of carrier-borne aircraft two-period form pulley blocks ejector is divided to one section of speed-raising and two sections of two stages of speed-raising, When accelerate ejection work, the piston (2) in high steam gas push cylinder barrel (1), piston (2) pushes one section of pulley (5) Often move forward 1m, so that it may make one section of rope (4) on one section of pulley (5) that two sections of pulleys (25) be pulled to move 2m.Two sections of pulleys (25) mobile 2m, but the acceleration that can make two sections of ropes (6) that ejection shuttle (39) be pulled to carry out 4m to carrier-borne aircraft is launched.Launch shuttle (39) it is to be in direct contact with carrier-borne aircraft on ejection orbit (41), the power of rope, which is passed to carrier-borne aircraft, carries out acceleration ejection.Bullet One section of pulley (5) during penetrating: two sections of pulleys (25): the ratio by displacement distance in the ejection carrier-borne aircraft three same time is 1: 2: 4, the speed ratio of three also 1: 2: 4.When equal objects can be taken inertia by outer force effect and accelerate, the speed that is reached V is with the required relationship with external work W：Square, the i.e. V^2 ∝ W, so accelerator directly proportional to external work W used of speed V Middle three's equal unit quality the ratio of diligent W be equal to the ratio of three's velocity squared, i.e. w: two sections of pulleys of one section of pulley (5) (25) w: by ejection carrier-borne aircraft w=1^2: 2^2: 4^2=1: 4: 16.One section of pulley (5) 1kg mass in accelerator can be obtained It is to accelerate diligent 1/16 by ejection carrier-borne aircraft 1kg mass to accelerate work(used, i.e., one section of pulley (5) itself 16kg mass adds It is fast diligent only equal to by the work(of ejection carrier-borne aircraft 1kg mass acceleration.Two sections of pulley (25) 4kg mass accelerate work(used can only Equal to by the work(of ejection carrier-borne aircraft 1kg mass acceleration, it is low add that carrier-borne aircraft two-period form pulley blocks ejector, which runs component can be, Fast energy consumption quality.It is one section of pulley (5) to launch shuttle (39) for comparing and accelerate energy consumption by ejection carrier-borne aircraft unit mass 16 times, be 4 times of two sections of pulleys (25), referred to as：Height accelerates energy consumption quality.Carrier-borne aircraft two-period form pulley blocks ejector is to use itself The low acceleration energy consumption quality operation component of low speed carries out high speed ejection to carrier-borne aircraft.Two sections of ropes of pulley blocks are accelerating ejection process Middle sole mass accelerates to consume certain energy.Rope movement turns over half bowlder of pulley, accelerates inertia to become forward in rope The direction of centrifugal force, power is consistent with the forward thrust direction of pulley, and two power are ejection acting together with, and ropes is waited to go to cunning Take turns another side when energy release finishes the state of becoming stationary at, account for about total length 92% rope turn over pulley after there is no sole mass Consume energy.For very short rope for braking, 8% rope for accounting for about total length has sole mass energy consumption after the completion of ejection.Accelerate Accelerate mobile rope longest quality amount big when ejection process just starts, sole mass accelerates energy consumption also just maximum, because just starting Rope movement speed minimum is accelerated to turn over the forward centrifugal force of pulley also just minimum.Pulley is constantly turned over mobile rope is accelerated Become stationary state to the another side of pulley, accelerates the shorter and shorter quality of mobile rope more and more lighter, sole mass is made to accelerate Energy consumption is also smaller and smaller, and mobile speed is but getting faster, and turns over that forward centrifugal force when pulley is also increasing, and rope is bullet It is also just increasing to penetrate acting.To acceleration ejection last period rope itself acceleration energy consumption minimization, energy is released to ejection acting Maximum, rope are consumption energy accelerating ejection front half section, and the second half section is to release energy.Just make up the period after ejection process Air pressure decline ejection force deficiency problem.Rope is that ejection force excessively high when acceleration ejection process is started is adjusted to ejection The hypodynamic second half section.Posture is directly erected immediately below ejection orbit (41) in two sections of pulley (25) positions.Cylinder barrel (1) and one section of pulley (5) for installation site on the side of two sections of pulleys (25), one section of pulley (5) posture can be put down can be oblique, depending on installation space condition, As long as the direction of one section of pulley (5) grooving is in the center that one section of rope (4) pulls two sections of pulleys (25) mobile.Bullet It is the 1/4 of piston (2) thrust to the ejection force of carrier-borne aircraft to penetrate shuttle (39).

It is expected that：Carrier-borne aircraft two-period form pulley blocks ejector launches work and runs component：Piston (2) and one section of pulley (5) matter Amount 3200kg=3.2T is scaled high acceleration energy consumption quality 3.2*1/16=0.2T.Two sections of pulleys (25) and a bit of rope are total Meter 1.2T is scaled high acceleration energy consumption quality 1.2T*1/4=0.3T.Launch shuttle (39) and the total 0.35T of a bit of rope, warship Carrier aircraft two-period form pulley blocks ejector itself energy consumption mass conversion in launching work accelerates energy consumption quality for 0.2+0.3+ at height 0.35=0.85T, quality of materials titanium and iron calculate, if less with carbon, aramid fiber light material calculating quality.It sees on the net Steam ejection displacement component piston and load transfer device quality 2T are more, just without the low portion for accelerating energy consumption quality in 1/16 and 1/4 Part, because its moving component is complete as by ejection carrier-borne aircraft speed.The electromagnetic launch heavy moving parts of Electromagnetical ejector Than the sole mass bigger of steam.The buffering brake weight of the two also wants greatly more.Carrier-borne aircraft two-period form pulley blocks ejector utilizes Two-period form roller design, eccentric outer ring type pulley (8) design and piston (2) are designed with one section of pulley (5) clutch, make its very great Cheng Degree, which is reduced, itself to be accelerated energy consumption and reduces buffering brake pressure after the completion of launching.

After the completion of accelerating ejection work, by intercepting rope (11) to carrier-borne aircraft two-period form pulley blocks ejector displacement component Carry out brake interception, make its stop in the Engagement Area (12) (ejector intercepting system and Liaoning warship carrier-borne aircraft land warship when use Intercepting system construction it is identical).Drive electronic osmanthus hook vehicle (48) from ejection starting point by the motor on electric hook vehicle (48) again (42) Engagement Area (12) position is moved to, ejection shuttle (39) back is connected to ejection shuttle (39) impaction automatic coupling, by Aircraft carrier active force drives energy storage winch (50), the ejection shuttle for making energy storage rope (46) that electric hook vehicle (48) hook be pulled (39), ejection shuttle (39) is withdrawn into ejection starting point (42), ejection shuttle (39) and next frame carrier-borne aircraft from buffering area (12) Connection, electric hook vehicle (48) unclamp hook.At this time because of the interconnection of each component power of pulley blocks, piston (2) and pulley blocks are each Movement parts be also all withdrawn into ejection work before position, high pressure gas also by piston (2) be pressed back into high pressure steam boiler or It is set to recycle (high pressure gas can press dimension high pressure gas with high steam also available air) in gascollecting cap cylinder (7).It is carrier-borne Machine two-period form pulley blocks ejector energy storage is completed, and can be launched next time.

Carrier-borne aircraft two-period form pulley blocks ejector critical piece size and ejection parameter designing：1. ejection force and ejection travel Design：Cylinder barrel (1) long 2030cm (piston (2) effectively impulse stroke 2000cm), cylinder barrel (1) internal diameter is also piston (2) diameter 110cm, cross-sectional area 9503cm^2, high pressure gas pressure 40kg/cm^2.Piston (2) thrust=9503cm^2*40kg/cm^2 =38012kg=380T is converted into ejection force=380/4=of the ejection shuttle (39) to carrier-borne aircraft by two-period form pulley blocks 95T, then 8% frictional force of ejection system (estimated value) is deducted, net ejection force 87.4T, then add carrier-borne aircraft itself motor power 25T, the total ejection propulsion of carrier-borne aircraft are 112.4T.Launch shuttle (39) ejection travel=piston (2) impulse stroke 2000cm*4= 80m.2. ejection acceleration quality includes：Carrier-borne aircraft Maximum Take-off Mass 32.5T.Ejection system itself acceleration components quality (is estimated Evaluation)：Launch shuttle (39) high energy consumption quality 0.35T, piston (2) and one section of pulley (5) (titanium material) low energy consumption quality 3.2T*1/16=high energy consumption quality 0.2T, two sections of pulley (25) 1.2T*1/4=high energy consumption quality 0.3T.Total ejection accelerates matter Measure 32.5T+0.35+0.2T+0.3T=33.35T.3. launching carrier-borne aircraft acceleration=total ejection propulsion/total ejection accelerates matter Measure * g=112..4T/33.35T*9.8m/S^2=33m/S^2.4. carrier-borne aircraft launches end speed=33m/S^2* square roots (80mx2 ÷ 33m/s^2)=33m/s^2* square roots 4.8484s^2=33m/S^2*2.2019s=72.66m/s.Because of ejection End high pressure gas pressure decreases, and speed is about 70m/s, then Air Canada mother moves forward speed about 10m/S, and carrier-borne aircraft takes off Speed reaches 80m/S.As the fore deck of Liaoning warship is upturned, with certain inertia that moves upwards when making aircraft from warship, then have Air can make aircraft have even more than ten seconds several seconds itself acceleration time, to reach the speed of aircraft flight the climbing power of wing Degree.

The obvious advantage of carrier-borne aircraft two-period form pulley blocks ejector：One, it is that ejector transmits power using pulley blocks, is to use Itself low speed is low to accelerate energy consumption mass motion component to convey power to the ejection shuttle (39) and carrier-borne aircraft of high-speed motion.Itself adds Fast energy-consuming parts accelerate energy consumption 16 times or 4 times smaller than the acceleration energy consumption component of steam catapult per kg unit masses, steam ejection The moving component of device with by ejection carrier-borne aircraft be to move synchronously speed, as the low of carrier-borne aircraft two-period form pulley blocks ejector adds Fast energy consumption mass motion component.The steam catapult seen on the net itself power transmission heavy moving parts about 2T is more, carrier-borne aircraft two-period form It is about 0.85T that pulley blocks ejector itself power transmission moving component in launching work, which is converted into high acceleration energy consumption quality, itself adds Fast energy consumption is 2~3 times smaller than steam catapult, and buffering brake is also much smaller.It runs acceleration components quality titanium and iron calculates.If Meter can optimize aspect, if 1. self-operating component carbon fiber or other low specific gravity materials, itself accelerates energy consumption that can be much less. 2. the displacement component to losing piston (2) thrust after the completion of ejection suddenly freely travels forward, 2m or so contacts interception rope again (11) it brakes, there are a short rebound periods to make it do rebound motion.It is passed a part for consumption energy itself is accelerated Continue to do acceleration ejection to boat carrier aircraft, and self-operating component is made to slow down, reduces energy consumption and brake pressure.Carrier-borne aircraft two after optimization Segmentation pulley blocks ejector in launching work displacement component energy consumption can by height accelerate energy consumption quality 0.85T be reduced to 0.5T with Under.

Two, it avoids as steam catapult cylinder barrel opens the trouble that big breach gas leaks from the beginning to the end, it is no longer necessary to big Breach carries out maintenance work.

Three, two sections of ropes of two-period form pulley blocks sole mass in accelerating ejection process accelerates to consume certain energy, turns Become centrifugal force when crossing pulley and energy is released to ejection acting again.Accelerate ejection section rope to be equal to nothing and itself accelerate energy consumption, Rope is that ejection force excessively high when starting in acceleration ejection process was adjusted to the ejection hypodynamic second half section.Ejection is completed Buffering brake problem is also not present in it afterwards.

Four, it is the ejection force for ensuring to have enough when steam catapult is launched, to ejection latter end cylinder barrel since ejection Enough gas pressure intensities will be kept, so it is substantially substance to enter the high pressure hot gas of entire cylinder barrel from high pressure steam boiler Product is non-bloating, almost without gas expansion for doing work is utilized.High pressure high fever energized gases just discharge after the completion of ejection, energy Utilization rate is extremely low, and the huge power of aircraft carrier when doing ejection work is caused all to feel insufficient.Carrier-borne aircraft two-period form pulley blocks launch Device is to carry out ejection energy storage to high pressure gas using aircraft carrier active force, and high pressure gas is Ke Xunhuanliyong, and no matter is aircraft carrier active force Steam turbine or other engines can all utilize gas expansion for doing work very well, and energy conversion mechanical efficiency is made to reach optimum state, Capacity usage ratio several times higher than the disposable utilization rate not expanded using high pressure hot gas of steam catapult.Save energy Also save fresh water.

Five, steam catapult can directly provide high steam using the high-pressure boiler of aircraft carrier.But high pressure hot gas Storage time is very short, and heat dissipation energy consumption is serious, loses high fever and has reformed into water and does not have pressure, war preparedness period to need heat make-up at any time Gas pressure, component need corrosion protection：Heat preservation thermal protection layer is done to reduce thermal energy consumption.Carrier-borne aircraft two-period form pulley blocks ejector can Use high pressure superheated steam, it is possible to use air high pressure gas, it is more efficient using air high pressure gas, only it need to have air pressure Contracting machine by the high pressure gas in gascollecting cap cylinder (7) fill can long term storage with use, later only mended with air compressor Fill the gas a little leaked.Use air compressing high pressure gas ejector first choice thus.

Six, in ejection quality carrier-borne aircraft of different sizes, steam catapult is just difficult, and carrier-borne aircraft two-period form pulley blocks Ejector, it is contemplated that as soon as four sets of pulley blocks ejector hosts are mounted side by side in an aircraft carrier, one long gascollecting cap cylinder (7) is horizontal It is connected in the tail portion of four cylinder barrels (1) and with four cylinder barrels (1), carrier-borne aircraft bullet is carried out to 4 cylinder letter (1) input high pressure gas It penetrates, each cylinder barrel (1) also plays the role of storage and adjustment high pressure gas pressure.All Deng piston (2) position in 4 cylinder barrels (1) The gas pressure intensity highest at cylinder barrel (1) tail portion, can carry out the ejection of biggest quality carrier-borne aircraft, and launching cradle secondary frequencies at this time are also most It is high.Etc. one of piston (2) in cylinder barrel (1) mouth, the high pressure gas in gascollecting cap cylinder (7) just flows into this cylinder barrel (1), it reforms into gascollecting cap cylinder (7), and high pressure gas volume increases a cylinder letter by gascollecting cap cylinder (7) about 100m^3 (1) capacity 20m^3 is at 120m^3, and high pressure gas volume, which increases, makes gas pressure intensity reduce, excess-three cylinder barrel (1) tail portion Piston (2) ejection propulsion is just corresponding to be reduced.If two or three cylinder barrels (1) will as gascollecting cap cylinder (7) gas pressure intensity The reduction for having second, third time, then penetrating thrust also should mutually have the second, third times to reduce.High pressure gas is adjusted using cylinder barrel capacity Body pressure, to determine the size of ejection propulsion, to launch the carrier-borne aircraft of weight different quality.In general launch compared with Multiaircraft bombing task is not had when the aircraft of lightweight.Also a set of big ejection force can be designed in four sets of ejectors, to pre- Alert machine, fuel charger are launched.

Seven, simple structure is stablized securely and reliably, and maintaining is convenient.
