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.
