Premixed carbon dioxide pneumatic laser driven by combustion of continuous rotary detonation rocket

Abstract

The invention discloses a premixed carbon dioxide pneumatic laser driven by the combustion of a continuous rotary detonation rocket. The premixed carbon dioxide pneumatic laser comprises a continuousrotary detonation combustion device, a transition section, a CO2 pneumatic laser generation device and an exhaust section. The continuous rotary detonation combustion device is used for generating a high-temperature and high-pressure fuel gas heat source as a total energy source of downstream output laser and comprises a shell, a central cone, a rotary detonation combustion chamber and an injection panel, the transition section enables the fuel gas behind the combustion device to adapt to configuration changes, and enables the fuel gas to stably flow to the front of an array spray pipe with the total pressure loss as small as possible, the CO2 pneumatic laser generating device comprises the array spray pipe and an optical cavity, and the exhaust section enables a product gas after light emitting to be rapidly exhausted to the outside. The continuous rotary detonation rocket combustion device is adopted as a pumping source, so that the produced laser is high in efficiency, and the energy is saved. The premixed carbon dioxide pneumatic laser can be used on a rocket or an aircraft boosted by a rocket, and not only can generate thrust, but also can generate laser without increasing theload, and can also be used as a high-power continuous intense laser light source on the ground.

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 continuous rotation 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...

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
