Description
Technical field
The present invention relates to taking off and recovery method of a kind of aircraft carrier-based aircraft, specifically a kind of method that adopts rotating mechanism aircraft carrier-based aircraft to be taken off and reclaim.
Background technology
Aircraft carrier (Aircraft Carrier) is called for short " aircraft carrier ", " aircraft carrier ", is a kind of warship that can provide military aircraft to take off and land.Aircraft carrier be a kind of be the large-scale water surface naval vessels of main operational weapon with carrier-borne aircraft.Modern aircraft carrier and carrier-borne aircraft have become the intensive military systems engineering of hightech.
Before adopting bar none, the general design of at present medium-sized or above in the world aircraft carrier floats bow, square stern, and the flush deck, oblique angle, the big outer high freeboard that floats of band, island formula bridge is put on the right side, enclosed hangar and topside elevator.Aircraft carrier also needs some special equipments, and as check cable (being used for normal landing), arresting net (being used for forced landing) helps the system of falling etc.
The landing technology of tradition carrier-borne aircraft is as follows:
1, taking off of carrier-borne aircraft:
Except that aircraft ejection kit electromagnetic launch of future generation just under study for action, the mode that traditional fixed wing aircraft takes off from aircraft carrier can be divided following two kinds.
First kind is the steam catapult-assisted take-off, uses a flat deck as airstrip.A steam-powered catapult-launching gear drive aircraft reaches takeoff speed when taking off in two seconds.Steam has launched two kinds of ejection modes, and a kind of is that front-wheel launches, and directly hauls aircraft nose wheel by slide block when launching and takes off.Need not 8～10 people come to hang tow rope and subtracted tow rope for aircraft like this, the time of launching shortens, and aircraft safety is good.Second kind is that the tow rope formula is launched, and as its name suggests, quickens to take off with steel rope traction aircraft exactly, and this ejection mode is older, and everyway is good not as the former.
The ejector of catapult-assisted take-off is actually a big steam piston, has quickened to fly away from warship with helping aircraft.Steam promotes the slide block of piston and interlock when abrupt release, with 3-4G will weigh 40 tons aircraft in 100 meters by the static speed that accelerates to up to 175 joints.Every ejector launches and is spaced apart half by one minute.But in fact, launch attack echelons and need 25 to 32 minutes.Ejector makes that warship becomes possibility on the heavy high performance airplane, but ejector not only greatly but also heavy, reach about 100 tons, manufacture and design expensive complexity, have only the U.S. one family using at present, and need to consume a large amount of water, whenever launch and once need consume fresh water 1.5-2 ton, ejector uses restriction many, and every ejector launched on average and was no more than 70-100 time every day, and the aircraft turnout is low.The maintenance requirement height of ejector, whenever launching needs marine grounding maintenance for 3000-3200 time or returns the port maintenance, and carrier-borne aircraft also must greatly be strengthened body, thereby gains in weight.
The process of catapult-assisted take-off is as follows:
The front-wheel of aircraft is hung in the launching apparatus, and the official of operation launching apparatus must know that the model of aircraft and load-carrying regulate launching apparatus.
In order to protect personnel and the apparatus on the deck, to load onto the wallboard of shielding aircraft jet stream in the aircraft back.
The aviator augments horsepower after obtaining take off clearance, prevents airplane motion with brake simultaneously.
The aviator will decontrol brake in the signal that obtains taking off, launching apparatus starting is simultaneously ejected runway with aircraft.This process continued for 1.5 seconds altogether.
Second kind is that the swash plate cunning is takeoff and flown.Some aircraft carrier has one " diving tower " to help to take off at its deck front end.Aircraft power with oneself when taking off is jumped onto via the assistance of diving tower in the air.This mode of taking off does not need complicated catapult-launching gear, and weight when still taking off and the efficient of taking off are not as launching.Sliding takeofing flies need not special equipment, and low to the housing construction requirement, warship is easy on the land airplane, its turnout and catapult-assisted take-off are suitable, can set out continuously and do not have the restriction of ejector access times, work that aircraft remains control when flying away from warship, and the catapult-assisted take-off initial stage is actually and does not have control.But require aircraft to have high thrust-weight ratio and short takeoff ability, taking off may not be heavily loaded, and engine thrust descends under the hot environment, must just can take off with water injection.
Aircraft carrier all must be helped take off with the above speed griping of 20 joints (36 kilometers/hour) in both cases.Power CTOL fixed wing aircraft need advance at utmost speed down with the wind by aircraft carrier, improves true wind speed, reduces warship warship on the opportunity relative velocity that taking off simultaneously.
2, the landing of carrier-borne aircraft (recovery)
On aircraft carrier, land, especially under night or situation, need very high flight skill in bad weather.The landing process is as follows:
At first the aircraft of Hui Guiing will enter around the ring-like course line of mother ship carrier to reduce flying height and speed, may also need to break away from waiting landing course line sometimes and go to carry out air refuelling.
The speed of aircraft will be reduced to the stage of almost stall when landing.The aviator stretches out drop, wing flap and air flap with arresting hook, keep certain speed and downslide speed.Landing official on the boat warship commands aircraft landing, and he constantly tells the aviator, and what he is from the deviation of optimal cases; Light prompt aviator on the aircraft carrier, whether the angle during decline is correct.
At the flight deck rear portion of aircraft carrier four interception ropes are arranged.The aviator of landing must allow arresting hook hang up wherein one.He should hang up the 3rd under the best circumstances.
The aviator must force down aircraft fully when landing, and he can guarantee to hook an interception rope like this.Simultaneously driving engine must be reached maximum again, also can within the shortest time, not quicken to leave the deck, come back to the landing course line if hang up the interception rope like this.The interception rope is by hydraulic braking, and it can stop aircraft in two seconds and 50 meters.The aviator can be reduced to slow train and leave the dropping zone according to the indication of the ground crew on the deck thrust with driving engine.
In case of emergency, damaged such as the hook of aircraft, aircraft can't use the interception rope to stop, and can assist forced landing by pull-up interception net above deck.Or aircraft pull-up once more, landing again.
Because weakness such as aircraft carrier is being born many vital tasks of fight, carrier aircraft, takeoff and landing, causes the aircraft carrier build huge, and it is slow partially, vulnerable to take action, costly.Particularly Guan Jian landing technology and equipment thereof---ejector is more impossible from external acquisition, buys the spare part problem that also has from other country.
Summary of the invention
In the technical present situation of landing, the purpose of this invention is to provide taking off and recovery method and device thereof of a kind of later-model aircraft carrier-based aircraft at present aircraft carrier.The present invention changes existing warship bodily form formula, can reduce warship body build, strengthens alerting ability, reduce use cost.
