Embodiment Construction

[0011] The technical solution will be further described as an embodiment below in conjunction with the drawings.

[0012] Reference figure 1 , 2 The cylinder 18 of the aircraft carrier aircraft catapult is a long shape, and its length is such that the acceleration distance for pulling the pulley 3 to run can reach the speed requirement of the aircraft 4 for taking off. The inner cavity of the cylinder requires high smoothness so that the two ends of the piston 17 running in it are air-tight to each other. The end covers at both ends of the cylinder and the cylinder body are firmly combined, and the seal is air-proof. The wire rope 1 penetrates into the cavity and the piston from both ends of the cylinder. The two ends of 17 are fixedly connected, and the oil seal 20 of the front cover 19 of the cylinder shall not leak air. The forward high-pressure intake pipe 16 is connected from the side wall of the front of the cylinder to the inside of the end cover, and a control valve 15 is...

Abstract

The invention discloses an aircraft catapult of an aircraft carrier. The aircraft catapult comprises a cylinder, two steel wire ropes for transferring power, an acceleration pulley, a grooved rail for the pulley to run, a reverse pulley, a high-pressure pipeline for communicating the cylinder with an air filling system, and an air storing and filling mechanism, and is characterized in that four fixed pulleys are located at four corners of a rectangle; the two ends of a cylinder piston are connected by a steel wire rope; and one steel wire rope goes around the two fixed pulleys in front of the cylinder and is fixedly connected with the rear end of the pulley, and the other steel wire rope goes around the other two fixed pulleys behind the cylinder and is fixedly connected with the front end of the pulley. The high-pressure air pump pumps in an air storage tank; and when in use, the air storage tank fills high-pressure airflow into the cylinder, and the high-pressure airflow pushes the piston to drive the steel wire ropes connected with the pulley to perform accelerated motion so that an aircraft on the pulley can obtain the take-off speed in proper time.

Description

Technical field [0001] The invention relates to an aircraft carrier aircraft catapult. Background technique [0002] The most mature aircraft take-off catapult used on aircraft carriers is the steam catapult. It uses high-pressure steam as the power, and the thrust generated by the steam engine piston drives the reciprocating vehicle to suddenly accelerate to a speed of more than 100 m / s at a distance of less than 100 meters. , So that the aircraft reaches the take-off speed and ejects the aircraft into the air. However, this method requires a large boiler of the aircraft carrier to provide steam, which consumes a large amount of energy from the aircraft carrier, which increases the use cost of the carrier aircraft. , The steam catapult is a long-stroke reciprocating steam engine, which is composed of a launching system, a steam system, a towing rope tensioning system, a lubrication and control system, and the structure is more complex. The technical requirements for use are al...
