Gravity acceleration catapult of aircraft carrier shipboard aircraft

Abstract

The invention relates to a gravitational acceleration ejection of an aircraft carrier-based aircraft. According to the law of free fall motion, mg=ejection thrust, ν=g·t=ejection velocity ν, and a streamlined counterweight iron with huge mass is used to pull the wire rope and the ejection. The two fixed pulleys, front and rear, change the traction force of the wire rope that falls into the sea water freely into the ejection take-off thrust in the horizontal direction, which is referred to as the gravitational acceleration ejection. The gravitational acceleration ejection starts from zero, and there is no impact damage to the carrier-based aircraft at the beginning of the ejection, so it can also eject small unmanned reconnaissance aircraft, bombers, aerial tankers, anti-submarine aircraft, and early warning aircraft. It solves the problem that the carrier-based aircraft with a large amount of bombs and various take-off speeds cannot take off due to the short rolling distance of the aircraft carrier. Gravitational acceleration ejection, low energy consumption, simple structure, safe, reliable, fast and practical.

Description

1. Technical field [0001] The invention relates to a gravity acceleration ejection of an aircraft carrier-based aircraft. The streamlined weight iron of huge mass is used to pull the steel wire rope and the catapult, and the traction force of the steel wire rope freely falling into the seawater is changed to the horizontal direction by two fixed pulleys at the front and rear. The ejection take-off thrust is referred to as gravity acceleration ejection. The acceleration of gravity can eject from zero, and there is no impact damage to the carrier-based aircraft at the beginning of the ejection, so it can also eject small unmanned reconnaissance aircraft, bombers, aerial refueling aircraft, anti-submarine aircraft, and early warning aircraft. It solves the problem that the carrier-based aircraft with a large amount of ammunition and various aircraft with different take-off speeds cannot take off due to the short run distance of the aircraft carrier. 2.

Problems solved by technology

[0002] The take-off methods of carrier-based aircraft: vertical take-off, ski-jump take-off, and catapult take-off, and ski-jump take-off: because the carrier-based aircraft with a short run distance and a large amount of bombs, early warning aircraft, bombers, tankers, and anti-submarine aircraft and small unmanned reconnaissance aircraft cannot take off, which affects combat effectiveness

Therefore, the developed United States adopts steam ejection, which consumes a large amount of steam and fresh water, consumes a lot of energy, has low efficiency, is difficult to maintain, and has high technical requirements. The steam pressure at the beginning of steam ejection is the largest, and the ejection speed is also the largest. The carrier-based aircraft produces a huge impact force, which requires that the carrier-based aircraft must have anti-collision capabilities, otherwise the carrier-based aircraft will be crashed, so it is impossible to eject small unmanned reconnaissance aircraft, anti-submarine aircraft, bombers and early warning aircraft

Therefore, electromagnetic ejection is being developed, but electromagnetic ejection requires a strong power supply. Conventional-powered aircraft carriers cannot solve the problem of strong electrical energy supply. Nuclear-powered aircraft carriers must be able to solve the problem of strong electrical energy. The requirements for electromagnetic ejection technology are more stringent. So far, developed The United States has also failed to truly realize electromagnetic ejection
