| 摘 要： | 针对气动和化学激光器现有超声速扩压器的不足，提出一种新型式的扩压器——附面层抽气扩压器。以常温空气为介质，通过改变扩压器附面层抽吸能力、混合室隔板长度、扩压器出口反压及主进气流量等条件进行试验。结果表明：该型式扩压器在一定条件下可以有效隔离光腔流场，改善壁面压力分布，且其长度尺寸可比常规扩压器缩短约25％。

| Abstract: | A new style boundary scoop pumping diffuser was development.The essential performance had been achieved by testing through changing boundary layer ejector pumping capacity,mixing chamber clapboard length,the counterpressure,main inlet mass flux and so on.The results prove this diffuser could effectively isolate laser cavity flow field,improving wall pressure distribution.And may be attention,the diffuser length could be cut 25%,compared to the common. |
