【摘要】:载气密闭循环氧碘化学激光器技术是一种有望大幅减小氧碘化学激光器体积和降低运行成本的技术,然而至今鲜见相关实验报道。采用超音速喷管加双螺杆真空泵建成了模拟实验装置,并通过测量超音速喷管前后和双螺杆真空泵出入口处的气动参数的方法开展了载气密闭循环氧碘化学激光器的可行性研究和工作稳定性模拟实验研究。模拟实验研究结果证明了该技术的可行性,发现并分析了其光腔压力随双螺杆真空泵转速提高而出现压力拐点的现象,确定了其稳定运行工作条件,为实现载气密闭循环氧碘化学激光器的真正运行和小型化奠定了良好的基础。
[Abstract]:The closed cycle oxygen-iodine chemical laser with carrier gas is a promising technology to reduce the volume and operation cost of the oxygen-iodine chemical laser. However, there are few related experimental reports. Supersonic nozzle and twin-screw vacuum pump are used to build the simulation experimental device. By measuring the aerodynamic parameters at the inlet of the supersonic nozzle and the inlet of the twin-screw vacuum pump, the feasibility study and the simulation experiment of the working stability of the closed cycle oxygen-iodine chemical laser with carrier gas are carried out. The simulation experiment is carried out. The results show that the technology is feasible. The phenomenon that the pressure of the optical cavity appears inflection point with the increase of the rotating speed of the twin screw vacuum pump is found and analyzed, and the working conditions of its stable operation are determined. It lays a good foundation for the real operation and miniaturization of the closed cycle oxygen-iodine chemical laser with carrier gas.
