Aircraft catapult utilizing hydraulic power and hinge connecting rod structure

Abstract

The invention relates to an aircraft catapult utilizing hydraulic power and a hinge connecting rod structure. The catapult is composed of a hydraulic power part, a mechanical transmission part and an engine base, wherein a hydraulic transmission part is composed of five high-pressure oil cylinders; a hinge structure is adopted among all the connecting rods (5) of the hinge connecting rod structure; a guide rod (8) is transversely arranged in front of the engine base (1), and the two ends of the guide rod (8) are respectively provided with a hinge lug (9) which can slide along the guide rod (8); and the five high-pressure oil cylinders drive the hinge connecting rod structure to catapult an aircraft. The catapult of the invention has small volume, small occupied naval vessel space and high efficiency, and provides ideal driving force and ejection force for launching various aircrafts on aircraft carriers; the thrust is large, thus providing possibility of launching heavy aircrafts on the aircraft carriers; and the catapult has simple process and low construction cost, and does not consume invaluable fresh water resources for naval vessels sailing at sea.

Description

technical field [0001] The invention relates to an aircraft catapult device for an aircraft carrier, in particular to an aircraft catapult utilizing hydraulic power and a hinge-link mechanical device. Background technique [0002] At present, there are two ways for the fixed-wing carrier-based aircraft of an aircraft carrier to take off from the aircraft carrier, one is ski jump takeoff, and the other is catapult takeoff. Due to political and military reasons, the West imposed a technological blockade on China and the former Soviet Union. The former Soviet Union or Russia used ski jumps to replace steam catapults when developing aircraft carriers. Although using a ski jump to take off can replace a catapult, it is reported that the carrier-based aircraft Su-33 can only carry a load of about 2 tons with 60% fuel. The Su-33's external capacity is increased to 6 tons when it is full of fuel, and only then can it fully exert its full combat performance as a heavy fighter. [0...

AI Technical Summary

Problems solved by technology

If the sealing strength of the sealing strip is greater and the sealing is better, then the resistance to the sealing knife will be greater, and the sealing strip will wear out faster, thus causing air leakage and lowering the efficiency. It is said that the efficiency of the steam catapult can only reach 5%. about
