Description

Aircraft catapult utilizing hydraulic power and hinge connecting rod structure
Technical field
The utility model relates to the aircraft ejection kit of aircraft carrier, especially relates to the aircraft catapult that utilizes hydraulic power and link-hinge-type mechanical device.
Background technology
At present, the fixed-wing carrier-borne aircraft of aircraft carrier has two kinds of modes of taking off from carrier-based, and a kind of is that sliding jumping up flies, and a kind of is catapult-assisted take-off.Because political and military, blockade on new techniques is carried out before to the China and the Soviet Union in the west, and the former Soviet Union or Russia use the sliding formula of jumping to play sudden alternative steam catapult when the development aircraft carrier.Can substitute ejector though use the sliding formula of jumping to take off, according to reports, carrier-borne aircraft Soviet Union sliding the jumping up of-33 usefulness flies, having the load that to hang under 60% the fuel condition about 2 tons, if use ejector just can make the plug-in ability of Soviet Union-33 under full oil condition, bring up to 6 tons, wait whole operational performances that can give full play of by this as heavy weight fighter.
Use catapult-launching gear, the carrier-borne aircraft that takes off from aircraft carrier relies on the steam ejector to obtain an initial acceleration, thereby is issued to enough takeoff speeds in the limited condition of ground run distance.Catapult-assisted take-off flies to compare with sliding jumping up, the catapult-assisted take-off large-scale early warning plane that can take off, and heavy weight fighter can be expired oily high gross weight takeoff: because of catapult-assisted take-off can reduce the oil consumption of taking off, thereby increased early warning range and combat radius.The sliding formula of the jumping large-scale early warning plane that can not take off that takes off, and since heavy weight fighter when taking off bullet-loading capacity and fuel load be restricted, consumption of fuel is big when taking off, thereby has influenced fighting effect greatly.
The steam ejector is one of visual plant of present large-scale through type aircraft carrier, and an ejector per minute can launch two carrier-borne aircrafts.The steam ejector has high reliability, up to now, does not have airplane fault because of device proper in nearly ten million time catapult-assisted take-off to meet accident.
But, though the steam ejector has above-mentioned advantage, but its complex structure, the steam ejector is made up of external equipment and ejection machine and control system, and external equipment comprises: devices such as desalting plant, hydraulic accumulator, high-pressure hydraulic pump, high-pressure pump, high pressure tank, ventilation flue, operated pneumatic valve, safety valve, ejection valve, gas line and boiler; Ejection machine comprises: open cylinder, piston, sealing arrangement, sealing cutter, transmission arm, tow rope, reciprocal cable wire, dead sheave, directive slide track etc.; Control system has: pressure sensor, temperature sensor, position transduser and computer system etc. constitute complete ejector system.It relates to multi-field technology: metal smelt technology, metalworking technology, welding technique, computer software control technology and field engineering etc.Require all very highly from design to installation, what especially the steam ejector adopted is open cylinder, its maximum difficult point be piston in the open cylinder motion, the sealing problem of sealing cutter during through opening.If the big more sealing of the sealing intensity of sealing band is good more, the resistance that petty sealing cutter is subjected to is just big more, and the wearing and tearing of sealing band are also fast more, therefore, cause gas leakage, lowers efficiency, and it is said that the efficient of steam ejector only can reach about 5%.
It is the direction that China naval develops in the future to a certain extent that China builds aircraft carrier voluntarily.From world wide, it is extremely challenging making a strong aircraft-carrier battle group.Technology such as the steam ejector of indispensability, carrier-borne aircraft, check cable, large-scale elevator are all grasped in America and Europe and even the U.S.'s one tame hand on the aircraft carrier, and also can not have any country to sell Chinese advanced military technology abroad, the following construction of Chinese Navy aircraft carrier need solve the problem of ejector, do not solve and handle well if this problem Chinese Navy is not made great efforts, progress that petty following aircraft carrier that will directly influence Chinese Navy is built and Chinese Navy blue-water capable fleet establish an army the time.
