Slotted type steam-driven catapult for airplane short-distance take-off

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...

AI Technical Summary

Problems solved by technology

Because of the shortcomings in the design of this type of steam catapult, it has caused a series of negative effects on production, use, maintenance and repair

The use reliability is reduced, the maintenance work is complicated, the key parts are easy to wear, the field maintenance is difficult, and it is necessary to regularly enter the factory for overhaul

The prospect of the electromagnetic catapult being developed in the United States is also not clear. It is a typical technology-intensive and capital-intensive engineering project. The cost of R&D and manufacturing is very expensive, the product is not economical, and the new technology also brings uncertainty about reliability.
