Problems solved by technology

On the one hand, helium resources are scarce, expensive, and costly to use, which is not conducive to the industrial application of oxygen-iodine chemical lasers; , the oxygen-iodine chemical laser with helium as the diluent gas can no longer adapt to the application of this new low-temperature molecular sieve adsorption pump, because the zeolite molecular sieve used in the low-temperature molecular sieve adsorption pump can only effectively adsorb oxygen at low temperature (the oxygen-iodine chemical laser itself generates gas) and nitrogen

Abstract

The invention discloses a supersonic oxiodide mixed sprayer of oxiodide chemical laser based on nitrogen as dilute gas, which is characterized by the following: setting two rows of iodine sprayer at subsonic segment of sprayer with caliber at phi0.5mm; setting the distance between two iodine sprayers at 2mm and the even distance of two rows of sprayer and sprayer throat at 3-5mm; designing the Mach number of sprayer outlet at 2.2-2.8 and each unit throat breadth of sprayer multiplied by 2 at 4-6mm; setting the breadth of sprayer outlet at 10-15mm. The invention saves the operating cost greatly, which is beneficial for industrial applying of oxiodide chemical laser.

Description

technical field [0001] The invention relates to a supersonic oxygen-iodine mixing nozzle of an oxygen-iodine chemical laser, in particular to a supersonic oxygen-iodine mixing nozzle of an oxygen-iodine chemical laser using nitrogen as a diluent gas. Background technique [0002] The existing chemical oxygen iodine laser (COIL) uses a large amount of helium as a diluent gas. On the one hand, helium resources are scarce, expensive, and costly to use, which is not conducive to the industrial application of oxygen-iodine chemical lasers; , the oxygen-iodine chemical laser with helium as the diluent gas can no longer adapt to the application of this new low-temperature molecular sieve adsorption pump, because the zeolite molecular sieve used in the low-temperature molecular sieve adsorption pump can only effectively absorb oxygen at low temperature (the oxygen-iodine chemical laser itself generates gas) and nitrogen. [0003] Therefore, if the oxygen iodine chemical laser can ...
