Mechanical catapult for carrier-based aircraft

Abstract

The invention discloses a mechanical catapult for carrier-based aircraft. The mechanical catapult comprises a transmission shaft, a winch, clutches, brakes, a flywheel, a wire rope, a runway, and a slide. The mechanical catapult is technically characterized in that except the brakes disposed on a housing and the runway and the slide both disposed on a deck, the rest are all disposed on the transmission shaft; two trays are disposed on the transmission shaft and include one which supports a winch assembly and the other which supports the clutches. The winch assembly is braked to stop rotating, the clutches rotate in the center of the winch along with the transmission shaft, engaging-disengaging sliders are inserted into connections of the winch before catapulting, the winch is driven to rotate with the transmission shaft so as to wind the wire rope onto the winch, and the slide is pulled to drive an aircraft to take off. Catapulting powers are various; a water turbine and a gas turbine are taken as examples in the invention; when the water turbine is used as a power source, water is driven in by self-power of an aircraft carrier through an inflow gate, or a high-pressure water pump is driven by a motor, a diesel engine or the like to impact an impeller, and power is generated; when the gas turbine is used as a power source, power is transmitted to the transmission shaft through a reducer so that catapulting is available.

Description

technical field [0001] The invention relates to a launch device for carrier-based aircraft designed by using the principle of a hydroelectric generator. Its stator is similar to the winch of the launch device, and its rotor is similar to a clutch rotating in the middle of the winch. When the two are combined, the winch winches A catapult device in which the shuttle in the slideway is pulled by a wire rope to drive the aircraft to take off. It imitates the umbrella-shaped vertical design of the Three Gorges hydroelectric generator, and uses the mechanical power generated by the hydroturbine to eject. More specifically, it is a mechanical ship Carrier catapult. Background technique [0002] At present, the only mature ejection technology in the world is the steam catapult of the United States, and the electromagnetic catapult is still in the experimental stage. As for the flywheel energy storage catapult tested by the United States in the 1940s, it was abandoned because the cl...

AI Technical Summary

Problems solved by technology

[0003] Although the steam catapult has 50 years of mature use technology, its use cost and manufacturing cost are high. Each ejection requires 1 ton of fresh water, and seawater desalination devices, water storage tanks, gas storage tanks, boilers and other facilities are required, especially the manufacturing process. Complicated, difficult to master the sealing technology, weighing more than 500 tons, taking up a lot of space, etc.
