Problems solved by technology

[0002] Steam catapults have been used on ten Minitz-class nuclear-powered aircraft carriers in the United States. Electromagnetic catapults have been successfully tested on land-based airports and are currently being tested on Ford-class nuclear-powered aircraft carriers. The above two catapults are fatal in the application process. The disadvantage is that the structure is complicated, the price is expensive, and the energy consumption is high, so it can only be used or tested on a nuclear-powered aircraft carrier or a super-nuclear-powered aircraft carrier. At present, the carrier-based aircraft on a conventional-powered aircraft carrier can only take off by ski jumping. Since there is no catapult, Ski-jump carrier-based aircraft cannot take off with a full load, and large fixed-wing aircraft such as anti-submarine aircraft, early-warning aircraft, and cargo fixed-wing aircraft cannot board the aircraft carrier. This restricts the combat capability of aircraft carriers and restricts the development of Chinese aircraft carriers.
[0003] In the prior art, the inventor disclosed a catapult module and The method of decentralized energy storage and concentrated work, the ejection module all adopts external power equipment, the disadvantage is that the power density of the ejection module is small, the dynamic energy storage power is small, and the carrier-based aircraft with a mass of more than 60 tons needs more integrated configurations. The ejection module takes up a lot of space, and the ejection power cannot be flexibly and rationally allocated according to different ejection qualities, which cannot meet the needs of domestic aircraft carrier-based aircraft catapults

Embodiment 1

[0040] The principle of decentralized energy storage and concentrated work of the catapult system is as follows:

[0041]1) Each ejection module is equipped with two built-in energy storage motors. At the same time, the speed of the built-in energy storage motor is controlled by the frequency converter. The rotor of the built-in energy storage motor rotates on the transmission shaft without load and drives the energy storage power take-off to rotate to enter dynamic energy storage. state, the energy storage concave disc on the power take-off is a flywheel whose diameter and mass are equivalent to the rotor of the motor, the disc brake is in the braking state, the clutch is in the released state, the transmission shaft is stationary, and the wire rope wound on the transmission shaft is not pulled by the shuttle. Doing work, standing still at the starting point of the ejection runway above the homing module;

[0042] When the ejection module ejects a large-mass object, the two b...

Embodiment 2

[0051] The method of using the multi-purpose dynamic energy storage carrier-based aircraft catapult system. The ejection system is composed of an ejection module, a homing module, a runway ditch module, an electric energy deployment module and an electric energy storage module. In order to prevent multiple carrier-based aircraft from ejecting and taking off at the same time In the event of a collision accident, most of the four ejection systems on the aircraft carrier take turns to eject and take off the carrier-based aircraft, and at most two carrier-based aircraft can eject and take off at the same time. The electrical energy generated by the built-in generator of each ejection module is uniformly allocated and used, and the electrical energy is uniformly allocated to the ejection system that is being ejected or stored in the electrical energy storage module for backup;

[0052] The built-in motor in the ejection module is a dual-purpose motor for electric power generation. T...

Abstract

The invention provides a multi-functional dynamic energy storage type shipboard aircraft ejector system and a using method thereof. The system comprises an ejection module, a returning module and an external power device, wherein the ejection module and the returning module have the same structure; the returning module is matched with one or more than one ejection module to perform disperse dynamic energy storage and is used for concentrating all kinetic energy to drive a steel wire rope to draw a gliding shuttle in a two-way manner to act in a straight line, so that the shipboard aircraft is ejected and lifted off. The system has a simple structure, low cost and high energy utilization, is completely modularized and programmably controlled, is adjustable in ejection quality and ejection speed, is convenient for processing, assembling and training, is an essential device for military academy training and entertainment places, can be directly applied to ejection of aircraft on a carrier by increasing the number of ejection modules or increasing the power of an energy storage motor and the external power device, and is a required equipment for aircraft carriers of China.
