| Research on calibration technique of thrust force and related influence parameters，in order to solve the field calibration problem of the important test parameters related to the measurement and conversion of engine thrust. These parameters include thrust, fuel flow, temperature, humidity, pressure, speed, air flow, nozzle area, etc. The accurate measurement of these parameters is the premise to obtain the engine thrust and the converted thrust. In this paper, the test parameters, control parameters related to aero engine test and thrust measurement, measurement tools, and traceability standards and requirements used in the study of aerodynamic correction method for additional thrust resistance of indoor test bench are reviewed. A relatively complete traceability system is formed to guide the reliability requirements of the test data in the research work, so as to ensure that these basic work do not have problems as far as possible. |
