Embodiment 1

[0023] For the carrier-based aircraft catapult of the present embodiment, refer to the attached figure 1 , 2 , comprising a cable machine 1, a double-barrel cylinder 2, a piston 6 is installed in the double-barrel cylinder 2, a traction frame 3 is arranged on the upper part of the double-barrel cylinder 2, a tractor 4 is connected to the top of the traction frame 3, and a deck is installed on the tractor 4, So that the carrier aircraft can slide and take off on the deck.

[0024] There is a cylinder gap in the center of the top of the double-barrel cylinder 2, and the two pistons 6 are fixedly connected by a traction frame 3 in a U-shaped structure. The bottom of the traction frame 3 is provided with a reciprocating vehicle 7, and the two ends of the traction frame 3 are connected by a baffle plate 3-1. The reciprocating car 7 is placed between the traction frame 3 and the baffle plate 3-1, pulleys 9 are installed on both sides of the reciprocating car, the steel cable goes a...

Embodiment 2

[0030] In order to better realize the vacuum seal between the piston and the double cylinder cylinder, the carrier-based aircraft catapult of this embodiment has been further improved on the basis of Embodiment 1, that is, a piston sealing ring 6 is installed inside the piston. -1.

Embodiment 3

[0032] The carrier-based aircraft catapult of this embodiment is further optimized for Embodiment 1 and Embodiment 2, that is, the wire cable machine 1 is connected with a wire winder 14 to prevent position deviation during the reciprocating motion of the wire cable.

Abstract

The invention relates to a catapult and particularly relates to a carrier-based aircraft catapult. The carrier-based aircraft catapult comprises a steel cable machine, a double-barrel air cylinder, a traction frame, a traction device and a sliding speed reducer, wherein the double-barrel air cylinder is internally provided with pistons; an air cylinder seam is arranged at the center of the top of the double-barrel air cylinder; the two pistons are fixedly connected with the traction frame with a U-shaped structure; the top of the traction frame is connected with the traction device; a reciprocal vehicle is arranged at the bottom of the traction frame; the two ends of the traction frame are connected through a baffle; the reciprocal vehicle is located between the traction frame and the baffle; pulley wheels are mounted on the two sides of the reciprocal vehicle; a steel cable is wound around the pulley wheels to return back to the steel cable machine; the top of the traction frame is connected with a steel cable; the steel cable is wound around two fixed pulley wheels at the tail end of the double-barrel air cylinder and returns back to the steel cable machine. The catapult is great in thrust, high in efficiency and stable in catapulting acceleration; a sealing strip does not need to be replaced frequently and freshwater is not used; no steam environment pollution is caused, no magnetic shielding is formed, hidden dangers of damaging the system are small, and the safety is high. The carrier-based aircraft catapult is simple in structure and convenient to maintain. Particularly, the carrier-based aircraft catapult c can be used for large-size and small-size carrier-based aircrafts and ground-based catapulting.

Description

technical field [0001] The invention relates to a catapult, in particular to a carrier aircraft catapult. Background technique [0002] The device on the aircraft carrier that promotes the carrier-based aircraft to increase the take-off speed and shorten the roll distance, the full name is the carrier-based aircraft take-off catapult, referred to as the catapult. [0003] At present, the widely used steam catapult technology is mature. It has the advantages of large full load capacity, long endurance, fast launch, 2 sorties per minute, and strong actual combat capability. It can complete the ejection of fixed-wing aircraft in all-weather environments. For example, Carrier-based aircraft, airborne early warning aircraft; but there are restrictions on small UAVs. [0004] The principle of the steam catapult is to use the steam generated by the nuclear power boiler of the aircraft carrier to be pressurized by the high-pressure gas storage tank, and the valve is controlled to a...
