高恢复压力氟化氘增益发生器技术研究
|
摘要
增益发生器是影响高能氟化氘(DF)化学激光器恢复压力的核心组件,采用传统增益发生器的DF激光器尾气恢复压力约为6.7kPa。设计了一种紧凑化TRIP型增益发生器,突破了高腔压运转、主气流气幕和激射腔边壁回流抑制等关键技术,实现了DF激光器尾气恢复压力的大幅提高。实验结果表明,在面积比流量为1.3～3.3g·s-1·cm-2的范围内,随着增益发生器面积比流量的提高,激光器尾气恢复压力有效提高,面积比功率持续增加;在面积比流量为3.3g·s-1·cm-2条件下,DF激光器可以实现26.7kPa背压(海拔10km大气压)下的高效运行。
The gain generator assembly is the core component which influences the recovered pressure of high energy deuterium fluoride(DF)chemical laser.The recovered pressure of DF laser exhaust gas using traditional gain generator assembly is about 6.7 kPa.A compact type of TRIP gain generator assembly was designed,with breakthroughs on the key techniques of running with high cavity pressure,primary stream curtain and restraining regurgitant stream of the laser cavity boundary wall.The recovered pressure of the DF laser was increased obviously.The test results show that the recovered pressure of the laser exhaust gas and the power flux were both increased effectively with the increase of the mass flow rate in the range of 1.3～3.3 g·s-1·cm-2.When the mass flow rate was 3.3 g·s-1·cm-2,the DF laser could operate efficiently at 26.7 kPa background pressure(air pressure of 10 km altitude).
