Abstract

The invention relates to a nozzle module for transversal flow injection iodine mixing nozzle experiment research. The module is applied to the experiment research of an ultrasonic chemical oxygen-iodine laser key part, i.e., a nozzle module. The module, through a nozzle fixation plate capable of convenient dismounting and replacement, enables nozzles with various structural designs and a nozzle throat pitch to be conveniently replaced or adjusted. The establishment of the experiment apparatus provides convenience for the experiment research of a transversal flow injection iodine mixing nozzle array, and greatly improves the nozzle design of a chemical oxygen-iodine laser and the efficiency of air-flow operation condition experiment research.

Description

technical field [0001] The invention relates to a nozzle module used for experimental research on a lateral flow injection iodine mixing nozzle. This module is applied to the experimental research of the key component of the supersonic oxygen iodine chemical laser - the nozzle module. Background technique [0002] The current common supersonic oxygen iodine chemical laser (COIL) generally uses iodine and its carrier gas to be injected into the subsonic section upstream of the nozzle throat. Iodine injection in the subsonic section can achieve better mixing of the injected iodine and the main oxygen flow, and the dissociation of I2 can be realized in the highly diluted O2(a1Δ) flow with helium. These gain media are then expanded in a supersonic nozzle to lower the gas flow temperature, thereby lowering the threshold yield of O2(a1Δ) required to achieve population inversion and positive gain. This method has been successfully applied in many high-efficiency COIL devices. Ho...
