A Synchronous Carrier-borne Aircraft Catapult and a Method of Dispersing Energy Storage and Concentrating Work

Abstract

The invention provides a synchronous shipboard aircraft catapult and a dispersed energy storage and concentrated acting method. The synchronous shipboard aircraft catapult comprises a pneumatic device, an acting tunnel, a sliding shuttle tractor and a controller. The controller controls the pneumatic device to introduce high-pressure air into the two ends of the acting tunnel, the sliding shuttle tractor located in the acting tunnel is driven to move in a reciprocating manner at a high speed, a sliding shuttle is driven to be catapulted from a start point to an end point, and a shipboard aircraft is catapulted to lift off; and then the sliding shuttle is driven to automatically return to the catapulting start point, and kinetic energy of the pneumatic device is transmitted to the shipboard aircraft. Compared with various traditional catapults in the prior art, the synchronous shipboard aircraft catapult has the beneficial effects of being simple in structure, easy to machine, reliable in work, high in man-machine effect, small in occupied space, high in energy use rate, capable of saving energy by over 90%, free of pollution to the environment and easy to maintain, and therefore the tunnel type shipboard aircraft catapult can be used for column mounting of aircraft carriers in various power manners or land-based airports.

[0002] At present, there are two main types of aircraft carrier catapults that can be seen to be repeatedly operated. One is the steam catapults that are publicly used on 10 aircraft carrier battle groups in the United States. The traditional steam catapults are two open cylinders, which have high processing accuracy, difficulty in processing, and are durable. Poor performance, frequent maintenance, overhaul for three months for every 500-1000 sorties ejected, more than 500 maintenance personnel, high friction resistance of cylinder piston, low energy conversion rate, low use efficiency, high maintenance cost, and steam catapult needs nuclear reactor To provide high-pressure steam, two 200-cubic-meter steam storage tanks are required, which take up a lot of space, the system is complicated, and the manufacturing process is only mastered by the United States.

[0003] The second is the electromagnetic catapult being developed by the United States. The disadvantages are that the structure is complex, the cost is high, and the energy consumption is high. The electric power of 100,000 kilowatts is equivalent to the electricity consumption of the entire Shanghai. The forced energy storage mechanism converts the rotational kinetic energy into storage, and converts the rotational kinetic energy into electrical energy when it is used. The converted electrical energy is sent to the superconducting coil in the linear motor and converted into magnetic energy. The magnetic energy drives the mover to generate kinetic energy that drives the shuttle. After After four energy conversions, more than 60% of the 100,000-kilowatt electric energy has been lost, and less than 30% of the electric energy actually does work

Moreover, the conversion process not only produces a large amount of waste heat, which requires the rapid cooling of the low-temperature cooling system, but also produces a super-strong magnetic storm every time it is ejected. High-intensity magnetic storms will cause serious damage to the shipboard radar communication equipment. Therefore, the huge power consumption electromagnetic catapult can only It is used on Ford-class super nuclear-powered aircraft carriers in the United States, and researchers also publicly stated that it is still unknown whether electromagnetic catapults can completely replace steam catapults and be used on aircraft carriers in service in the future. At present, only the United States has mastered electromagnetic catapult technology. For those countries that have just started building conventionally powered aircraft carriers, spending huge sums of money to develop electromagnetic catapults with many disadvantages is indeed a blind choice that is not worth the candle
