Embodiment Construction

[0011] The main cylinder and the auxiliary cylinder are welded together in parallel, the main cylinder has a single opening, and the auxiliary cylinder has double openings symmetrically up and down. The length is about 7 to 10 meters, and each section is connected by a connector, which is laid and fixed on the base of the catapult under the deck. The ejection power is transmitted by the piston to the ejection rod through the opening blade, and the opening blade drives the composite steel cable to seal the opening groove of the cylinder forward. There is a lubricating oil chamber with strong oil circulation in each connector, which is used to lubricate and dissipate heat for the composite steel cable.

[0012] At the top of the catapult, there is a terminal damping cylinder about 2 to 3 meters long. After the ejection rod is separated from the aircraft, the air release valve is closed to compress the air in the cylinder to obtain damping force, and the piston with a speed of ab...

Abstract

The invention relates to a steam catapult which is important equipment for the taking off of the carrier aircraft of naval air force from the deck of the carrier. The one-way steam catapult with linear opening cylinder does not adopt the prior U-type-filling sealing technology, but a linear sealing technology with the combination of a composite steel rope and a counter cylinder to dynamically seal an opening steam main cylinder, which removes the defects of short sealing life and large maintenance of the U-type-filling sealing technology. Also, the steam catapult adopts back tracking motor-driven drag technology to realize the one way steam action of the catapult, thereby resolving the detects of large steam consumption of the U-type-filling sealing catapult and saving the valuable fresh water.

Description

1. Technical field [0001] Naval aviation carrier-based aircraft technology 2. Background technology [0002] At present, there are three ways for carrier-based aircraft to take off from an aircraft carrier: catapult takeoff, glide ramp takeoff, and vertical takeoff. [0003] Although taxi springboard takeoff and vertical takeoff are simple, the combat load of carrier-based aircraft is limited. Only catapult takeoff can achieve the full combat load of carrier-based aircraft. However, since the U-groove sealing technology patent of the open cylinder for catapult takeoff was bought by the United Kingdom to the United States, the catapult takeoff technology is basically monopolized by the United States now. [0004] Although the U-groove sealing technology of the open cylinder for catapult takeoff is relatively mature, it also has the disadvantages of complex technology, easy damage and large maintenance. 3. Contents of the invention [0005] The "wire-sealed open cylinder ...
