Pulse detonation rocket combustion-driven premixed carbon dioxide pneumatic laser

Abstract

The invention discloses a pulse detonation rocket combustion driven premixed carbon dioxide pneumatic laser which comprises a pulse detonation rocket combustion device, a transition section, a CO2 pneumatic laser generating device and an exhaust section. The pulse detonation rocket combustion device is used for generating a high temperature and high pressure gas heat source as the total energy source for downstream laser production and comprises a cylindrical shell, an oxidant injection panel and a spoiler spiral. The inner cavity of the cylindrical shell forms a pulse detonation combustion chamber. When the oxidant and the fuel are supplied in the pulse detonation combustion chamber and impacted and mixed evenly and ignited, pulse detonation combustion occurs in the pulse detonation combustion chamber under the action of turbulence spiral. The combusted gas passes through the CO2 pneumatic laser generating device to generate pulse laser. The pulse detonation rocket combustion device is used as a pump source so that the output laser has high efficiency and saves energy. When the device is used on rockets or aircrafts, it 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 pulse detonation rocket 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 medium...

Problems solved by technology

[0008] 2. CO due to traditional rocket combustion drive 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

[0009] 3. Conventional rocket combustion driven CO 2 The laser works in a continuous light output mode, and additional system complexity is required to output pulsed laser light
