Abstract

The invention discloses an air-sucking pulse detonation combustion driven pre-mixed carbon dioxide pneumatic laser which comprises an air-sucking pulse detonation combustion device, a transition section, a CO2 pneumatic laser generating device and an exhaust section. The air-sucking pulse detonation combustion device is used for generating a high temperature and high pressure gas heat source as atotal energy source for downstream laser output and comprises a shell, a center body, a rotating valve and a turbulent spiral. An air inlet channel is formed between the air inlet cone part of the center body and the conical shell. A propellant mixing zone is formed between the back of the air inlet channel and the rotating valve. The pulse detonation combustion chamber is located downstream of the rotating valve. The turbulent spiral is coaxially arranged in the pulse detonation combustion chamber. When the air-sucking aircraft flies at supersonic speed, the propellant pulse supply is realized by controlling the rotating valve to generate pulse detonation combustion, and the burned gas generates pulse laser after passing through the CO2 pneumatic laser generating device. The laser outputefficiency is high and the energy is saved. The device can generate both thrust and laser without increasing its load.

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 pulse 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, generating an active...
