Air-breathing Continuous Rotational Detonation Combustion Driven Premixed Carbon Dioxide Pneumatic Laser

Abstract

The invention discloses a premixed carbon dioxide pneumatic laser driven by an air-breathing continuous rotation detonation combustion, which comprises an air-breathing continuous rotation detonation combustion device, a transition section, a CO 2 Pneumatic laser generation device and exhaust section; air-breathing continuous rotary detonation combustion device is used to generate high-temperature and high-pressure gas heat source as the total energy source for downstream laser output, including the central body and cylindrical shell; the central body includes front to back The air intake cone, large cylinder, small cylinder and tail cone are arranged in sequence; the gap between the air intake cone and the front conical shell forms the air inlet, and the gap between the small cylinder and the rear cylindrical shell The gap forms a rotating detonation combustion chamber. The invention is applied to an air-breathing aircraft, adopts an air-breathing continuous rotating detonation combustion device as a pump source, and produces laser with high efficiency and saves energy. And while not increasing its load, the same air-breathing continuous rotation detonation combustion device can be used to generate both thrust and laser.

Description

technical field [0001] The present invention relates to CO 2 In the field of pneumatic lasers, especially a premixed carbon dioxide pneumatic laser driven by air-breathing continuous rotation detonation combustion. Background technique [0002] Gas lasers are the lasers with the most types, the widest wavelength distribution area and the widest application in the laser family. Its outstanding advantages are: the wavelength distribution area of ​​the spectral lines it emits is wide, the beam quality is high and the output power is large. Compared with other lasers, gas lasers also have the advantages of high conversion efficiency, simple structure, and low cost, so they have been widely used. [0003] The basic working principle of the gas laser: the energy is released through the pump source, so that the gas particles are selectively excited to a certain high energy level, thereby forming a population flip between the low energy level and a certain low energy level, genera...

AI Technical Summary

Problems solved by technology

[0008] 2. Due to the CO driven by conventional air-breathing combustion 2 The laser efficiency produced by the laser is low. Therefore, when producing a laser with a set output, the amount of fuel required is large and the energy efficiency ratio is low.

Moreover, due to the low light extraction rate and no special design, the large equipment volume makes it only used for ground light extraction experiments
