Catapult

Abstract

The invention discloses an aircraft carrier rocket assist catapult which is mainly composed of a catapult track, a booster rocket and a canister launcher. The catapult track is arranged on a hangar foreground of a shipboard aircraft. The shipboard aircraft catapults directly on the catapult track. The rear side of the catapult track and a hangar floor are located in the same plane and connected through a pin shaft, a catapult track groove is formed in the middle, the rocket canister launcher is arranged on the lower side, and an upper opening of the canister launcher is tightly attached to the track groove. A sliding block tractor is arranged in the groove. A tractor hanging machine pull rod part is arranged on the upper portion of the catapult track, and a rocket hanging device is arranged on the portion, stretching into the canister launcher, of the lower portion of the catapult track. A backflow discharge flue and the canister launcher are arranged side by side. The booster rocket can be repeatedly used. After a first airplane is ignited and launched, the canister launcher is blown, then an appropriate amount of liquid propellant is injected into the booster rocket, and ignition is carried for launching again. The front and back slope of the catapult track can be adjusted through a hydraulic lifting device, and the sliding block tractor and the canister launcher automatically return under the effect of a spring and the track slope.

Description

Technical field [0001] The invention relates to the military field, in particular to a rocket catapult for launching aircraft on an aircraft carrier. Background technique [0002] At present, there are three kinds of known carrier-based aircraft take-off technologies, one is the skateboard technology, the other is the steam ejection technology, and the third is the electromagnetic conversion ejection technology. There are very few countries in the world capable of developing and producing carrier-based aircraft catapults. The United States is the only country in the world that produces practical carrier-based aircraft steam catapults, and is also the first country to use electromagnetic carrier-based aircraft catapults. The French aircraft carrier The catapult can also only buy American products. It is reported that the difficulty of producing and developing steam catapults lies in the dense structure and materials, while the difficulty of electromagnetic catapults lies in ...

AI Technical Summary

Problems solved by technology

Its biggest flaw is that it cannot launch drones because the ejection power is too high. Because of the light weight of active drones, they will be torn apart by acceleration during ejection.

The advantages of electromagnetic catapults over steam catapults have not fundamentally eliminated the four major defects inherent in the catapult take-off mode, such as: the catapult itself still needs to seize huge structural and space resources on the aircraft carrier; The huge energy used by the catapult still needs to be provided by the power system of the aircraft carrier; the most deadly thing is that the research and development and production of the catapult require a long-term investment of huge resources, and the technical risk is high. , becoming a high "threshold" for the development of the aircraft carrier itself
