Design of Automatic Calibration System for Aeroengine Airborne Pressure Measurement Instruments

介绍了航空发动机机载压力测试设备的自动校准系统设计。该系统可实现机载压力测量设备的全自动现场校准,已成功应用于某型发动机机载压力测试设备的自动校准工作中。在0～7 MPa(表压、绝压)下进行测试、校准,准确度可达0.01%FS。

The automatic calibration system design of the aeroengine pressure measurement instruments was introduced.The automatic field calibration of airborne pressure measurement instruments was realized by the system which has been successfully adopted for the automatic calibration operation of an aeroengine airborne pressure measurement instruments.The testing and calibration accuracy reached to 0.01 % FS under 0~7 MPa（gauge pressure,absolute pressure）.
