Example Embodiment

[0037] First, fix the front wheel 7 of the carrier-based aircraft on the front wheel limiter 5 of the aircraft, and correct the direction of the wheels to ensure that all the wheels are parallel and aligned with the take-off direction. Open the intake valve 16, the high temperature and high pressure steam pushes the piston 2 forward, the piston 2 is connected to the piston ring 3, the piston ring 3 is connected to the shuttle 4, and the shuttle 4 is connected to the front wheel limiter 5 of the aircraft. Therefore, the piston 2 , Piston ring 3, shuttle 4, aircraft front wheel limiter 5, carrier aircraft 6 move forward together under the push of high temperature and high pressure steam. After the piston ring 3 slides over, under the action of the high temperature and high pressure steam expansion force, the sealing strip 22 presses the upper jaw of the cylinder square chamber 23 to block the cylinder gap and prevent the steam from leaking. At the moment when the piston 2 crosse...

Abstract

The invention discloses a slotted type steam-driven catapult for airplane short-distance take-off, belongs to the field of machinery, and relates to the carrier airplane take-off steam boosting technology. Due to the fact that the main part of an American steam-driven catapult on active service is a slotted steam cylinder, the related sealing technology is high in requirement, and machining, maintenance and repairing difficulties are high. In order to solve the problems, the slotted type steam-driven catapult adopts a creative slotted steam cylinder and sealing technology, machining, maintenance and repairing difficulties are lowered greatly, and independent production can be performed by China. By methods such as expanding the diameter of the steam cylinder, increasing steam pressure and parallelly connecting multiple groups of steam cylinders, catapulting power can be increased, catapulting take-off of heavy carrier airplanes such as Su-30MKK with full oil load can be achieved, the blow radius of the carrier airplanes of China is expanded to above 1500 kilometers, and territory, territorial waters and other national benefits of China can be guarded effectively.

Description

1. Technical field [0001] It belongs to the mechanical field and relates to the short-distance take-off steam boosting technology of aircraft carrier-borne aircraft. 2. Background technology [0002] In today's world, only the United States can manufacture short-distance take-off steam boosters for carrier-based aircraft, that is, steam catapults. It can eject carrier-based aircraft such as F-14 and F-18 and carrier-based early warning aircraft such as E-2, and its performance is very advanced. However, due to defects in the design of the C-13-1 and C-13-2 steam catapults currently in service in the United States, the requirements for materials are extremely stringent, and the processing and manufacturing are extremely difficult and costly. Even an industrial power like the Soviet Union failed to produce a qualified steam catapult after several efforts. The steam catapults on the French aircraft carrier Charles de Gaulle were also purchased from the United States. Now the...
