Description
One, technical field
The invention belongs to mechanical field, relate to the aircraft carrier-based aircraft lift-off technology.
Two, background technology
The Englishman has invented the sliding technology of flying of jumping up, make jet-propelled carrier-borne aircraft can be not by other external force only the power of dependence itself just can enrich the carrier-borne aircraft lift-off technology at carrier-based.The Soviet Union has just set up the aircraft carrier group of oneself by means of this technology.But there has been the sliding technology of flying of jumping up just to solve the problem of being and not being, it is compared and will be inferior very much with the steam catapult-assisted take-off, topmost shortcoming is that it can not help to take off at full capacity as the full oil of heavy carrier-borne aircraft of Soviet Union-33, has limited the performance of jet-propelled carrier-borne aircraft fighting capacity.
Though steam catapult can help the full oil of the carrier-borne aircraft as F-14 or F-18E/F to take off at full capacity, whole apparatus structure complexity, high to material and manufacturing technique requirent, cost is high.Though the Englishman has invented steam catapult, what really can manufacture steam catapult now has only the U.S. one family, and the steam catapult that uses on Air France Group's mother ship carrier is also purchased to the American.The bleed steam ejector though the Soviet citizen also looks on the bright side of things, however several times make great efforts to end in failure at last.
Though the electromagnetic launch device allegedly can help the full oil of carrier-borne aircraft to take off at full capacity, but it is typical hightech and fund-intensive project, need the technical threshold of leap also higher than steam catapult, the research and development expense also is astronomical figure, not that general industry country has the ability to develop, also has only the U.S. one family in the exploitation of carrying out this project from disclosed data, and the U.S. has also just just tested now and has launched F-35, also is a unknown number as for the heavy carrier-borne aircraft that whether can launch as F-14.
From the economy aspect, because sliding jump up that to fly apparatus structure very simple, carrier-borne aircraft adopts the sliding mode of jumping to take off to close the land very much the airport routine mode of taking off, thus its build and over-the-road expense minimum in above-mentioned three kinds of carrier-borne aircrafts take off mode.
Can develop the steam catapult of construction as U.S. C-13-1 type or C-13-2 type fully with the present industrial ability of China, even can develop than their superior steam catapult also, yet steam catapult is complex structure after all, has taken the space of aircraft carrier preciousness.
It is the highest mode of taking off of reliability that the airfield routine is taken off, and unfortunately the airfield routine mode occupied ground that takes off is big, is not suitable for aircraft carrier.
Three, summary of the invention
It is a kind of not with the power that can help aircraft dependence itself of the boosting power auxiliary device in the narrow space rolling start to the objective of the invention is development and Design.This device wants assist that the full oily full load of heavy carrier-borne aircraft of picture Soviet Union-30MKK to take off, and construction and over-the-road expense will be starkly lower than steam catapult and electromagnetic launch device, and the while reliability also will be apparently higher than steam catapult and electromagnetic launch device.
The present invention is divided into sliding race with the aircraft takeoff flow process and takes off two stages.Carrier-borne aircraft takes off sliding the race at straight rail of circular orbit.Carrier-borne aircraft is bundled on the coaster at first in the sliding race of circular orbit, when reaching takeoff speed, carrier-borne aircraft and coaster by inversion mechanism circular orbit and straight rail are engaged togather, coaster and carrier-borne aircraft are taken advantage of a situation and are transformed on the straight rail, coaster stop motion and carrier-borne aircraft takes off from warship under the effect of arresting gear.Supporting plate and flap are arranged on the coaster, and coaster supporting plate and flap tilt centnifugal force is evenly dispersed on three carrier-borne aircraft wheels to center of circle direction.The angle of inclination of coaster supporting plate and flap is regulated by inclination angle adjustor.
The path of motion of aircraft rolling start is circle-tangent line.It is on the circular orbit of a sealing that carrier-borne aircraft is slided when running, and has so just solved the sliding too short problem of stroke of running of the sliding mode that flies of jumping up.
Aircraft rolling start auxiliary device of the present invention not only can help 30 tonnes heavy carrier-borne aircraft rolling start as Soviet Union-30MKK, and can help more large-scale aircraft rolling start when the circular orbit diameter is enough big.
The power that aircraft rolling start auxiliary device of the present invention is based on carrier-borne aircraft itself is realized taking off, and does not rely on the speed of a ship or plane and the deck wind of aircraft carrier, can also implement the operation of taking off under the situation of aircraft carrier zero speed of a ship or plane.So just reduced the requirement to heavy aircraft carrier power, powered by conventional energy also can, therefore just saved construction and the operation and maintenance cost of aircraft carrier, under the situation of equal funds, can increase the quantity of aircraft carrier.
The mode that aircraft rolling start auxiliary device of the present invention can make the aviator take off with the airport routine that closes the land is most taken off, and has avoided infringement and the blackout phenomenon of steam catapult-assisted take-off to aviator's vertebra.
Aircraft rolling start auxiliary device of the present invention possesses the same function of steam catapult, even go even farther, but compare the high technical threshold of steam catapult and high construction operation expense, the laid down cost of carrier-borne aircraft rolling start auxiliary device of the present invention is very low, and the building technology threshold is also low than steam catapult, can finish fully with the industrial ability that China is present.
Aircraft rolling start auxiliary device of the present invention system is simple, does not have engine installation, and the natural environment and climate extremely well-adapted uses in extremely cold sea area and also can not freeze, and reliability is higher than steam catapult-assisted take-off mode and the sliding mode of flying of jumping up.
The mode rolling start that aircraft rolling start auxiliary device of the present invention can help aircraft to take off with the airport routine that closes the land most, fighter plane, fighter-bomber, attack plane, schoolaeroplane that so just makes China air and naval force airman active service etc. can both make the quantity of China's carrier-borne aircraft occupy advantage at carrier-based.
