Air-breathing premixed carbon dioxide pneumatic laser driven by continuous rotary detonation combustion

Abstract

The invention discloses an air-breathing premixed carbon dioxide pneumatic laser driven by continuous rotary detonation combustion. The laser comprises an air-breathing continuous rotary detonation combustion device, a transition section, a CO2 pneumatic laser generation device and an exhaust section. The air-breathing continuous rotary detonation combustion device is used for generating a high-temperature and high-pressure fuel gas heat source serving as total energy for downstream output laser, and comprises a center body and a cylindrical shell. The center body comprises an air inlet cone part, a large cylinder part, a small cylinder part and a tail cone part which are sequentially arranged from front to back. An air inlet channel is formed by a gap between the air inlet conical part and the front-end conical shell, and a rotary detonation combustion chamber is formed by a gap between the small cylindrical part and a rear-end cylindrical shell. The laser is applied to an air-breathing aircraft, and the air-breathing continuous rotary detonation combustion device is adopted as a pumping source; the generated laser is high in efficiency, and energy is saved. The same air-breathingcontinuous rotary detonation combustion device is adopted without increasing the load, so not only can thrust be generated, but also laser can be generated.

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
