摘　　要：介绍了与化学激光某种类型增益发生器相连的叶片式扩压器的设计及其试验研究,验证扩压器的压力恢复特性。对于激光器标准质量流率,通过实验获得了不同背景压力条件下,该扩压器静压曲线,以及功率下降率与背景压力的关系曲线,得到该质量流率的恢复压力数据。而且,在保持相同的配比(即相同的平均分子量和平均比热比)条件下,获得了激光器125%、150%倍的标准质量流率下,该扩压器的恢复压力数据。试验验证出随着质量流率的增加恢复压力呈线性增长趋势的规律。This paper discussed the design and test of the vaned diffuser for a sort of Gas Generate Assembly(GGA)of chemical laser,to find out the pressure recovery characteristic of the diffuser.In the test we obtained the pressure datum in different back pressure of the diffuser in certain mass flow rate of the GGA.And we get the recovery pressure datum of the diffuser in 125% & 150% of certain mass flow rate of the GGA,keeping the ratio of specific heat average and the molecular weight average the same in the different mass flow rate.And the tests proved that recovery pressure and the mass flow rate are increasing linearity.
