Steam catapult with parallel, series and separation functions

Abstract

The invention discloses a steam catapult with parallel, series and separation functions. The steam catapult comprises a shell, an air storage tank and an ejection unit. The ejection unit comprises a desk, a sliding block tunnel, a sliding block, a low-pressure cavity shell, a tunnel pipe, a cylinder, piston sleeves, a tapered frame and stamping water cylinders. The in-out flow of the front and rear single-double three stamping water cylinders are controlled by three step control valves separately, one-way valves and a switch valve are installed in pistons, the pistons are divided into two parts including pistons I and pistons II, the pistons I and the pistons II are fastened by bolts separately, and sliding ways and piston sleeves, corresponding to the sides of the pistons I, are composedof sleeve fame beams and are connected with tapered frame hollow columns and penetrate out of front covers to be connected with bearing beams. When the weight of a carrier is specified, the steam catapult can calculate the exact movement value of corresponding parts, pull rods are arranged at the centers the end faces of the pistons II, and the pistons II are internally provided with shaft cores and shaft core pistons for common use of ejection and back stroke. The steam catapult with the parallel, series and separation functions has flexible operation, reliable performance, high speed, high efficiency and good air tightness, and the heat utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of catapult equipment, in particular to a steam catapult with functions of parallel connection, series connection and separation. Background technique [0002] As we all know, an aircraft carrier is a large surface combat ship with very powerful attack power. Its powerful attack power depends on carrier-based fighters, electronic fighters and air early warning aircraft, and the aircraft on the aircraft carrier mainly have two types of ski-jump flight and ejection flight. my country's existing Liaoning aircraft carrier uses a ski-jump take-off method; however, the airborne early warning aircraft has a relatively large body weight and a fuel-efficient turboprop engine, so it cannot use a ski-jump take-off method; only the United States can manufacture carrier-based aircraft in the world today. Aircraft short-distance take-off steam booster device, that is, steam catapult. The steam catapult successfully develo...

AI Technical Summary

Problems solved by technology

The steam catapult successfully developed and put into use in the United States uses a slotted cylinder steam catapult system, which not only has a complex structure, takes up a lot of space, has poor maneuverability of the entire device, serious steam leakage and fresh water loss, is difficult to manufacture and install, and has a small ejection force. At the same time, most of the steam catapults currently developed use slotted cylinders, which are easily deformed under the action of high-temperature and high-pressure steam, and the ejection unit can only complete a single work order as a whole, and cannot be controlled separately
