摘要
针对JF-10氢氧爆轰驱动风洞运行的高焓高速状态，采用吸收光谱技术、皮托压力瞬态测量技术、电离探针等的测试方法，测量了自由流中一氧化氮的含量和离子浓度、皮托压力及其沿喷管出口半径方向的分布。并根据以上各项测量结果判断了自由流的非平衡程度。
Series advanced measurement techniques, such as a bsorptive spectros copy technique,pitot pressure measurement and ion probes are applied to measure properties of free stream in JF10 hydrogen oxygen detonation driven shock tun nel, which can run at high enthalpy condition. Concentration of nitric oxide in free stream. spatial distribution of pitot pressure at nozzle exit and ion densi ty are presented. The nonequilibrium degree is also evaluated.
