【摘要】：載氣密閉循環(huán)氧碘化學激光器技術是一種有望大幅減小氧碘化學激光器體積和降低運行成本的技術,然而至今鮮見相關實驗報道。采用超音速噴管加雙螺桿真空泵建成了模擬實驗裝置,并通過測量超音速噴管前后和雙螺桿真空泵出入口處的氣動參數(shù)的方法開展了載氣密閉循環(huán)氧碘化學激光器的可行性研究和工作穩(wěn)定性模擬實驗研究。模擬實驗研究結果證明了該技術的可行性,發(fā)現(xiàn)并分析了其光腔壓力隨雙螺桿真空泵轉(zhuǎn)速提高而出現(xiàn)壓力拐點的現(xiàn)象,確定了其穩(wěn)定運行工作條件,為實現(xiàn)載氣密閉循環(huán)氧碘化學激光器的真正運行和小型化奠定了良好的基礎。
[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.
