摘　　要：利用电加热管设计了小流量压气机温度畸变发生器,针对某小流量压气机的温度畸变要求,对温度畸变发生器进行畸变指数标定试验,得到满足温度畸变指数要求的畸变发生器运行参数、总压恢复系数和总压畸变指数;将温度畸变发生器安装至压气机试验件,进行压气机性能试验,得到压气机在温度畸变条件下的气动性能。结果表明:满足温度畸变指数要求的电加热管需运行4~5根,单根功率为3 kW,进口物理流量需不大于3 kg/s;在该畸变发生器运行参数下,压气机峰值效率最大下降了1.3%,喘振边界无明显影响。A small flow compressor temperature distortion generator was designed by using electric heating tubes. The operation parameters of the temperature distortion generator were calibrated with temperature distortion coefficient, and the total pressure recovery coefficient and pressure distortion coefficient were obtained. The temperature distortion generator was installed on the compressor test rig,and the aerodynamic performance of the compressor under the condition of temperature distortion was obtained. The results showed that 4-5 electric heating tubes were required to meet the requirements of temperature distortion coefficient,and the power of a single tube was 3 kW. The inlet physical mass flow must be less than 3 kg/s. Under the operating parameters of the distortion generator,the peak efficiency of the compressor decreased by 1. 3%at most,and the surge line had no significant change.
