Shipboard aircraft oil wedge two-stage type catapult

Abstract

A shipboard aircraft oil wedge two-stage type catapult pushes a piston (2) in a cylinder barrel (1) by using high pressure gas; the piston (2) pushes a first-stage slide block assembly (5) so that a first-stage steel strip (4) on the first-stage slide block assembly (5) pulls a second-stage oil wedge slide block (25); and a second-stage steel strip (6) on the second-stage oil wedge slide block (25) is also enabled to pull a catapulting slide shuttle (39) to catapult a shipboard aircraft in an accelerated manner. During accelerating, the speed of a moving part is 1 / 4 of the speed of the catapulted shipboard aircraft, the accelerating energy consumption of the material of the moving part per kg is only 1 / 16 of that of the catapulted shipboard aircraft per kg, and the steel strip in the accelerating stage has no mass accelerating energy consumption. After catapulting is finished, an energy storage winch (53) is driven by aircraft carrier power to pull the catapulting slide shuttle (39) back to a catapulting starting point (42); and at the moment, the high pressure gas is also compressed back into a high pressure gas storage cylinder (7) by using the piston (2) so that the high pressure gas is used in circulation to catapult the shipboard aircraft. Compared with the work-efficiency of a steam catapult using high pressure and high-thermal non-expanding gas to catapult for one time,the work-efficiency of the shipboard aircraft oil wedge two-stage type catapult is improved by multiple times. The shipboard aircraft oil wedge two-stage type catapult has the advantages of simple structure and safe permanent use.

Description

technical field [0001] A kind of high-pressure gas is used to push the piston (2) in the cylinder (1) to generate power, and the high-thrust and short-stroke motion force of the piston (2) is converted into a power suitable for the carrier-based aircraft through the two-stage oil wedge catapult of the carrier-based aircraft. The ejection force and ejection stroke used for ejection, this technology is to use low-speed running parts to eject the carrier-based aircraft at a uniform acceleration and high speed. Background technique [0002] It can be seen on the Internet: the steam catapult C-13 is an aircraft carrier-based aircraft catapult used by the US military. Its disadvantages are as follows: because the steam cylinder is too long, the dowel rod will sink in the middle if it is too long, and the quality is too heavy, so the ejection work cannot be carried out. Therefore, a large long slit was made on the cylinder from the beginning to the end, and the force of the piston...

AI Technical Summary

Problems solved by technology

Due to the inevitable heat dissipation of high-pressure and high-heat steam, it is necessary to replenish heat energy regularly, and a lot of fresh water will be wasted during ejection

Electromagnetic catapults output a large amount of electric current in a very short time to supersaturate the wires and electronic components, generating a lot of heat, requiring troublesome cooling equipment, large engines, and storage and conversion equipment for electric energy. Ejection and The total length of the buffer track is about 200m, occupying a large space
