Energy-gathered type shipboard aircraft catapult system with power generating function

Abstract

The invention provides an energy-gathered type shipboard aircraft catapult system with a power generating function. Output kinetic energy of multiple internal combustion generator units is gathered synchronously through clutches on transmission shafts of energy-gathered acceleration modules, stepless winching acceleration is conducted on a traction belt wound round the transmission shafts, and thegathered kinetic energy is transmitted to a shipboard aircraft through a sliding shuttle connected to the traction belt, so that the shipboard aircraft obtains the take-off accelerated speed. Due tothe fact that catapulting operation of the energy-gathered modules is conducted instantaneously and intermittently, the internal combustion generator units can continuously supply extra power to an aircraft carrier, and the energy use rate is over 99%. Due to the fact that all the kinetic energy is from internal combustion engines which are universal power devices, internal combustion electric generators are directly customized from an internal combustion electric generator factory, the energy-gathered acceleration modules are directly customized from a clutch production factory, a runway module is directly assembled through steel members made of universal steel, no technical obstacle exists in the production process, the production scale can be formed in the current year, a roadbed airport, an island-reef airport and aircraft carriers in various power forms can be quickly and popularly equipped, the traditional high-energy-consumption catapult technology is overturned, and the systemis the only choice for world aircraft carrier construction.

[0002] There are two main types of carrier-based aircraft catapults currently in service. One is the open use of steam catapults on 10 nuclear-powered aircraft carrier battle groups in the United States. Traditional steam catapults are mainly composed of two open cylinders, a gas storage tank and a nuclear reactor. , the nuclear reactor produces high-pressure steam and sends it to the gas storage tank for storage. The high-pressure steam drives the piston in the open cylinder to do work through the valve to convert the steam pressure into kinetic energy. Due to the high machining accuracy of the open cylinder, the processing is difficult and the durability is poor. Frequent maintenance is required. Every ejection 500 -1,000 sorties will be overhauled for three months, with more than 500 maintenance personnel, high cylinder piston friction resistance, low energy conversion rate, low use efficiency, high maintenance cost, and the steam catapult needs nuclear reactors to provide high-pressure steam, and two 200 The cubic meter steam storage tank takes 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 generates a super-strong magnetic storm every time it is ejected. High-intensity magnetic storms will cause serious damage to shipboard radar communication equipment. Therefore, electromagnetic catapults that consume a lot of energy are currently still It is still unknown whether the electromagnetic catapult can completely replace the steam catapult and be used on the future service aircraft carrier in the test on the newly built Ford-class super nuclear-powered aircraft carrier in the United States. It is indeed an unwise and unwise choice to develop an electromagnetic catapult with congenital technical obstacles with huge sums of money

[0004] The two open cylinders used in the steam catapult are driven by steam and the linear motor used in the electromagnetic catapult. The power consumption of the two catapults within 3 seconds is 70,000 kilowatts and 100,000 kilowatts respectively. The power consumption is large and the manufacturing difficulty is great. It is conceivable. Through the study of the two types of carrier-based aircraft catapults in the prior art, it can be seen that the two types of carrier-based aircraft catapults in the prior art are highly dependent and high-power-consuming equipment of the aircraft carrier, and the power consumption is large. Only nuclear-powered aircraft carriers or super-nuclear-powered aircraft carriers can be equipped, which is out of reach for developing countries or countries with only conventional-powered aircraft carriers. Therefore, there is an urgent need for a technology that breaks the Western technology monopoly and lowers the technical threshold of catapults. Provide a It can be used on a conventionally powered aircraft carrier, which not only does not rely on and consumes the power of the aircraft carrier, but also provides additional power or power for the aircraft carrier.
