燃烧驱动连续波氟化氢(氘)化学激光器——三维列阵小孔喷管研究

MIXING PROCESSES BEHIND THE NOZZLE BANK EXIT OF A SUPERSONIC CW HF/DF LASER

摘要: 文章针对燃烧驱动连续波氟化氢激光器分析了其喷管出口后的混合过程;同时也讨论了喷管设计参数、结构和加氢方式等对激光器输出功率、比功率的影响。实验表明在主喷管和副喷管之间混合距离为1.75mm时,用这种喷管的氟化氢激光器,比功率可达到 130J/g。

Abstract: The influence of the design parameters, the structure of the nozzle array as well as the mode of H₂ addition on the output power are discussed. A specific power of 130J/g has been obtained with a mixing distance of 1.75mm between the primary and secondary nozzles.
