Boosting work method is at random concentrated in a kind of belt carrier-borne aircraft booster system and dispersion accumulation of energy
Technical field
The present invention relates to a kind of military equipment technical field, boosting work method is at random concentrated in a kind of belt carrier-borne aircraft booster system and dispersion accumulation of energy specifically.
Background technology
At present, the carrier-based aircraft ejector of the use on the aircraft carrier mainly contains two kinds, and a kind of is the steam catapult that uses with on U.S. army's aircraft carrier, and this booster uses steam to be used as power and accelerates to take off by piston drive hauling hook pulling aircraft in the open cylinder.The steam catapult equipment volume is huge, occupies than large space complex manufacturing technology, also will consume a large amount of fresh water, be the cylinder that cracks because the steam catapult of the U.S. adopts, thereby steam leakage is big, energy consumption is big, cylinder packing spare is short service life, and the maintenance cost height is in severe cold area or winter, the steam that leaks can freeze above deck, have a strong impact on taking off or landing of carrier-borne aircraft, this also be U.S.'s aircraft carrier in the winter time action radius reduce, or dare not arrive the basic reason of arctic scope activity at all.Because technology is externally maintained secrecy, so have only U.S. army to be equipped with steam catapult at 11 aircraft carriers at present.
The shortcoming that steam catapult exists is as follows:
1) weight is big, volume is big, and nearly 1000 tons of steam power booster total weight can be divided into by function: 1. take-off system 2. steam units 3. playback systems 4. hydraulic efficiency pressure systems, 5. pre-power system 6. lubricating systems, 7. control system.These systems can be decomposed into more mini system again; Roughly be 1.6 *, 1.8=2.88 sq ms for laying the groove sectional area that cylinder reserves on the flight deck, consider again booster nearly 100 meters length, then the volume of this part taps into 300 cubic meters.The volume of two jars also more than 200 cubic meters, is added the place that devices such as gas pipeline occupy, and cumulative volume has been arrived 600 cubic meters, the cumulative volume of 4 cover boosters is 2400 cubic meters, as for weight, a cover booster has 1000 tons at least, and 4 covers just have 4000 tons;
2) very high to material, technological requirement.Now except the U.S., comprise that the big national capitals of naval such as Great Britain and France can not make, buy to the U.S.;
3) efficient is low, and is wasteful.One time boosting will consume 800-1000 kilograms of fresh water.Producing these steam earlier will be with sea water desalination, and the water with desalination is heated into high temperature and high pressure steam in boiler again.And with these steam-reformings become boosting power have only 4 % to 6 %! If carry out boosting with the minimum interval, need to consume the steam of aircraft carrier boiler 20%;
4) system complex, operating personal is numerous, and a booster needs operating personal and about 120 people of reform personnel.The Operation and maintenance personnel that portion's booster needs reach more than 500, complete account for about 10% of warship establishment, maintenance capacity is big, and whenever launching 400 to 500 sorties just need be by the maintenance of carrying out 1-2 days with the warship personnel;
5) be that to launch power big, ejector to the requirement of launching carrier-borne aircraft be requirement in a short period of time, the power of consume significant launches takeoff speed to the heavy carrier-borne aircraft of 35-60 ton with what break out formula in the distance of 90-100 rice.The power of maximum steam catapult is ten thousand kilowatts of 4.75-6.3333 now! And working application time has only .2.6 second! The nuclear reactor gross horsepower of the atomic aircraft of U.S.'s maximum is 280,000 horsepowers, amounts to about 200,000 kilowatts! And the power of a steam catapult will how 60,000 4 thousand watt! If not the large-scale storage tank help accumulation of energy by 2 100 cubic meters, in any case this nuclear reactor of 200,000 kilowatts also can not supply the 4th booster;
6) cost height, production technology is highly confidential, and steam catapult of the U.S. of known active service is 8,000 ten thousand dollars of prices at least, have only the U.S. to grasp production technology at present, and selling range of use is the U.S. and ally thereof.
Second kind is the electromagnetic type ejector, in view of the many disadvantages that steam catapult exists, 28 years consuming time of United States Navy, expensive 3,200,000,000 dollars, succeeded in developing the electromagnetic type ejector, though in the land success of the test, because bulky, power consumption is huge, structure is too complicated, stability is very unreliable, and can't adapt to marine humidity and the harsh environment of salt fog, so yet be in conceptual phase till now, aircraft carrier also dare not formally be equipped so far by U.S. army.
In sum, do not have carrier-based aircraft ejector, no matter the aircraft carrier size all can not form fighting capacity, the principle of steam catapult is exactly a big and long steam engine! The characteristics of steam engine are long work, rather than break out the work of formula, so, the mode of operation of his inborn incompatibility booster.The principle of electromagnetic type ejector is exactly a linear motor.His work characteristics is the same with steam engine, only is adapted to long work, and can not break out the work of formula.No matter steam catapult still is the electromagnetic type ejector, the huge energy of abrupt release all is to realize by accumulation of energy, consumption of power all is 6.4 ten thousand kilowatts, and steam catapult is that the steam storage tank by 2 100 cubic meters comes accumulation of energy, converts high pressure steam to mechanical kinetic energy by open cylinder; And the electromagnetic type ejector is to realize by the mode of forcing storage station, the so-called storage station that forces, exactly the electric energy in traditional power station being driven 8 8000 kilowatts of dual-purpose motors respectively rotates and carries out accumulation of energy, when the electromagnetic type ejector needs big electric current to do work, 8 electrical motors convert 8 electrical generators immediately to, to rotate potential energy converting and energy and become electric energy, electric energy is concentrated in the linear electric motors of electromagnetic launch device and convert magnetic energy to, drive the mover high-speed mobile by magnetic energy and convert kinetic energy to, energy will consume 30-50% in the multiple conversions process, since steam catapult and electromagnetic type ejector be during by steam pressure can and magnetic field potential energy carry out moment and do work, need zero energy big, so energy dissipation is huge, according to pertinent data, be actually used in the energy shortage 10% on the carrier-borne aircraft, be least economical two kinds and launch pattern.As taking off shown in the curve of Fig. 6, carrier-borne aircraft is initially just accepted huge tractive force taking off, so speed is fast, and along with the consumption of energy, the reducing of potential energy, speed descends gradually, the shadow representation energy consumption of curve below;
As shown in Figure 7, the carrier-borne aircraft rate of onset is low, but along with the increase of the release force of inertia of energy, speed is just more and more faster, the gesture that rises to appears in curve, takeoff speed curve when this boosting curve and carrier-borne aircraft are unloaded matches, the energy consumption of comparison diagram 6 curves below, and the shade under Fig. 7 curve is significantly less than Fig. 6, this is the principle of boosting at random advance of the present invention just, energy consumption is more little, for carrier-based aircraft ejector, just means to have more good exploitativeness.

The length of each layer driving band is placed in the speed time curve coordinate, makes speed time curve, as shown in Figure 7;
According to calculating: the total length of the 33rd layer of driving band is L=(LI+L2+ ... meter L21)=102.6, outmost turns driving band diameter is 1.6 meters, calculates the maximum gauge of tep reel and selects 2 meters for use, and the width of tep reel is decided on the width of driving band.
Known aircraft accelerates about 2.5 seconds of the departure time at 100 meters runways, per second rope woolding 33/2.5 ≈ 13 circles, driving band is 102 meters at 33 layers cumulative length, if select for use motor that power is provided, the rated speed of rotation of motor is 1500 rev/mins, and the per second rotating speed is 25 commentaries on classics, is adjusted into 13 revolutions per seconds by speed change, converter speed ratio 25/13 can reach the takeoff speed of carrier-borne aircraft for transmission shaft provides 13 revolutions per seconds rotating speed.
By above-mentioned calculating as can be seen, air speed was about 24 meters in first second, the aircraft stroke was about 70 meters in second second, 2.5 flight is 102 meters during second, driving band twines 44 circles altogether on transmission shaft, aircraft was run through runway whole process in 2.5 seconds, and accelerated mode and driving band the speed of wrap on tep reel of aircraft on the boosting runway is synchronous fully, and accelerated mode is hommization very, can not cause damage to chaufeur and aircraft.
Selecting for use of driving band, select the nylon6 chips base band for use, gross thickness 6-10cm, width 50-100cm, tensile strength are the 100-200 tons, if select the carbon fiber composite sheet base band of identical basal area for use, breaking strength can reach the 250-300 ton, and it is 33 tons that Soviet Union 33 is fully loaded with, and 3-10 times of above safety factor arranged, the boosting runway has only 0.6-1.2 rice at the deck groove width, and the degree of depth gets final product for 0.30-0.50 rice.
If power is selected diesel engine for use, diesel engine provides extra even acceleration by regulating throttle, the takeoff speed of carrier-borne aircraft can also be up and down 20 one 50% float.
Carrier-borne aircraft boosting step is as follows:
1) shuttle is positioned at the runway starting point, is connected with the carrier-borne aircraft nose-gear by hanging device, and aero-engine refuels, and waits for takeoff order;
2) takeoff order is assigned, the adhesive of boosting module power-transfer clutch, the whole energy of motor pass to transmission shaft by power-transfer clutch, transmission shaft rotates driving band is twined, and driving band passes to shuttle with shp, the starting of shuttle traction carrier-borne aircraft, along with driving band increases in the number of plies that transmission shaft twines, haulage speed is more and more faster, and shuttle moves to the runway terminal point, and carrier-borne aircraft reaches takeoff speed and takes off smoothly;
When 3) shuttle is about to arrive the runway terminal point, the movable length of meter counter accurate measurement driving band, the equal in length of meter counter pre-set length and runway, when equal in length that meter counter preseting length and driving band move, meter counter sends speed-slackening signal to control module, power-transfer clutch on the control module control boosting module discharges, stop to transmit power, drg on boosting module and the playback module is braked simultaneously, transmission shaft stops operating simultaneously on boosting module and the playback module, and shuttle accurately is positioned at the runway terminal point;
4) shuttle is after the runway terminal point stops, delay time 1-3 second, drg on boosting module and the playback module discharges simultaneously, power-transfer clutch adhesive on the playback module, the driving band that is wrapped on the boosting module transmission shaft oppositely twines on playback module transmission shaft, shuttle is moved to the runway starting point by the runway terminal point, meter counter measures the driving band transfer length again, after the driving band transfer length reaches setting value, meter counter sends speed-slackening signal to control module, and the power-transfer clutch on the control module control playback module discharges, and the drg on boosting module and the playback module is braked simultaneously, shuttle accurately is positioned on the runway starting point, prepares next sortie carrier-borne aircraft accelerated take-off.
