    Abstract
  • 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.
