Launching return linkage type high-power aircraft carrier catapult

Abstract

The invention provides a launching return linkage type high-power aircraft carrier catapult. A piston is driven to move vertically in a cylinder by respectively charging air to two ends of the bidirectional cylinder and exhausting, movable pulleys at the ends of piton pull rods at two ends of the piston are further driven to match with fixed pulleys on an upper and lower fixed pulley fixing rack to straighten and bend a traction rope and a return rope, and the traction rope and the return rope synchronously drive accelerating slippage or origin return of a sliding shuttle on a take-off runway, and launching flying of an aircraft carrier can be realized by accelerating motion of the sliding shuttle on a launching runway. The catapult has the characteristics of simple structure, standard modularized production, convenience in assembly and maintenance, safety in use, high automation degree, long service life and the like, and is easy to machine, install and use; and automatic control of launching of the aircraft carrier and automatic return of the sliding shuttle can be realized through an electric control four-way valve and a sensor which is arranged on the end point of the take-off runway.

Description

technical field [0001] The invention relates to a kind of military equipment, in particular to a high-power carrier-based aircraft catapult of an ejection return linkage type. Background technique [0002] An aircraft carrier is a large-scale maritime combat platform, or a mobile airport at sea. No matter what kind of carrier-based aircraft, such as attack aircraft, anti-submarine aircraft, early warning aircraft, transport aircraft, electronic warfare aircraft, etc., they must use catapults to short-circuit on the aircraft carrier. Taking off from an aircraft carrier with a full load, only a full load can form combat effectiveness and long-distance cruise. At present, more than a dozen aircraft carriers in service in the United States are equipped with steam catapults. The newly developed electromagnetic catapults have not yet been equipped with ships. Why should the neat catapult be replaced by an electromagnetic catapult? The reason is: [0003] 1) Steam catapults have h...

Problems solved by technology

[0004] 2) There is also high energy consumption. The conversion of steam energy into ejection power is only 4% to 6%, and each ejection of an aircraft requires a ton of fresh water steam;

[0005] 3) The operation is complicated, and a catapult requires about 120 operators and maintenance personnel

[0006] The applicant disclosed in the patent application No. 201010616996.0 a large-thrust multiplier and speed-up pneumatic aircraft carrier aircraft catapult. This technical solution uses a one-way cylinder ejection, and the traction winch returns. The disadvantage is that the one-way The piston rod of the cylinder is push-out type. In order to prevent the piston rod from bending forcefully, the diameter of the piston rod needs to be increased, which increases the weight of the cylinder and increases the manufacturing cost. In addition, the cylinder traction and the winch are used to return to the original position, which affects the catapult. The overall synchronization and coordination of the system reduces the operability and safety
