Tunnel type shipboard aircraft catapult capable of using multiple types of energy

Abstract

The invention provides a tunnel-type carrier-based aircraft catapult that can use multiple energy sources. The catapult includes a tunnel assembly, a tunnel trolley and a controller assembly. The tunnel trolley is set in the tunnel assembly and is controlled by the controller assembly. The tunnel assembly drives the tunnel trolley to run back and forth, drives the shuttle to eject the carrier aircraft from the starting point to the end point, and then drives the shuttle to automatically return to the ejection starting point to realize the transfer of high-energy medium energy to the carrier aircraft, which is different from the existing technology Compared with various traditional catapults, it has the advantages of simple structure, easy processing, reliable operation, small footprint, high energy utilization rate, no pollution to the environment, easy maintenance, and the most important thing is that it can use a variety of energy sources and working media to do work, etc. characteristics, so the tunnel-type carrier-based aircraft catapult catapult can be installed and used on aircraft carriers or land-based airports with various power forms.

Description

technical field [0001] The invention relates to the technical field of aircraft carrier equipment, in particular to a tunnel-type carrier-based aircraft catapult that can use multiple energy sources. Background technique [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 is required, every 500-1000 sorties will be overhauled for three months, the frictional resistance of the cylinder piston is large, the energy conversion rate is low, the use efficiency is low, and the maintenance cost is high, and the steam catapult needs the nuclear reactor to provide high-pressure steam.

[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 is required, every 500-1000 sorties will be overhauled for three months, the frictional resistance of the cylinder piston is large, the energy conversion rate is low, the use efficiency is low, and the maintenance cost is high, and the steam catapult needs the nuclear reactor to provide high-pressure steam. Two 200 cubic meter steam storage tanks 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 the actual power for doing work is less than 30%.

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
