Host of pulley block ejector

Abstract

The invention relates to a host of a pulley block ejector, which is suitable for ejecting aircraft carrier-borne aircraft. A piston (2) in a cylinder tube (1) is pushed by high-pressure gas, so as to drive a four-rope pulley block to pull an ejection sliding shuttle (39) to eject the carrier-borne aircraft. The working stroke ratio of a movable pulley block (25) to the ejection sliding shuttle (39) is 1:4, the acceleration ratio of the movable pulley block (25) to the ejection sliding shuttle (39) is 1:4, and the acceleration energy consumption ratio of the movable pulley block (25) to the ejection sliding shuttle (39) of equal mass is 1:16. Four times high-speed ejection to an ejected object by using a low-speed running component is realized, and the self mass acceleration energy consumption is low. An eccentric outer ring type pulley (5) is designed, and the piston (2) is separated from a connecting rod (3), so that the self energy consumption and the buffer braking force of the running component are greatly reduced; when the ejection sliding shuttle (39) is pulled back by an energy storage rope from a buffer end point (44) to an ejection starting point (42) to prepare for second-time ejection, the piston (2) is also driven to return to the tail of the cylinder tube, so as to push the high-pressure gas into an air storage cylinder (38) and finish storing energy. The high-pressure gas can be recycled, so as not to waste energy and fresh water like a steam ejector which uses non-expansion high-pressure hot gas once.

Description

technical field [0001] A technology that converts high-pressure steam or air high-pressure gas into high-thrust kinetic energy through the cylinder piston, and then converts the high-thrust kinetic energy into a force suitable for carrier-based aircraft for uniform acceleration and ejection conditions by a pulley block. This technology is used for carrier-based aircraft. Perform ejection. Background technique [0002] It can be seen on the Internet: ①The steam catapult C-13 is the carrier-based aircraft catapult used by the US military. Its disadvantages are as follows: because the steam cylinder is too long, the power transmission connecting rod will bend down in the middle if it is too long, and the mass is too large, so the ejection work cannot be carried out or the efficiency is extremely low. Therefore, a large long slit was made on the cylinder from the beginning to the end, and the force was transmitted from the piston to the ejection shuttle with the shortest distan...

AI Technical Summary

Problems solved by technology

Heating with fresh water into high-pressure steam consumes a lot of fresh water

②Electromagnetic catapults need to use a large number of energy storage batteries or capacitors to output a large amount of electric current in a very short time to make the wires and electronic components supersaturated and generate a lot of heat. They must have cooling equipment and large engines for ejection and The buffer track is more than 100m and takes up a lot of space
