Abstract
A performance test bench device for a centrifugal compressor under a variable working condition of an engine is composed of: a turbine back disk temperature simulator and the centrifugal compressor being coaxially arranged, and being sequentially connected with a speed regulator and a driver. Meanwhile, a thermocouple array is arranged on a surface of a simulator back plate. A temperature measurement probe is arranged at an inlet and an outlet of the centrifugal compressor, and a thermocouple array is also arranged on a surface of a cover plate of the centrifugal compressor and a surface of a rotating blade. An airflow passes through the inlet pipeline, the flow meter and the air inlet rectification system, is pressurized by the centrifugal compressor, and is then discharged by the outlet pipeline.
