摘　　要：燃烧效率是航空发动机的关键气动性能参数,其准确获取对提高航空发动机性能、节省燃油、减少排放及匹配燃烧室总体性能等都具有重要意义。针对航空发动机温升燃烧效率的准确获取问题,设计了高准确度的进口参考温度传感器、出口参考温度传感器和媒介温度传感器,将出口参考温度传感器与媒介温度传感器相结合,提出并使用测点修正因子,实现了航空发动机温升燃烧效率现场校准。结果表明:所采用的温升燃烧效率校准方法合理、结果可信,参考温度传感器所得温升燃烧效率与燃气分析燃烧效率的相对偏差为0.3%~2.1%。Combustion efficiency is a key pneumatic performance parameter of the aeroengine,and its accurate acquisition is important for improving performance quality of aeroengines,saving fuel,reducing emission and overall performance matching of the combustion chamber.For accurate acquistion of the aeroengine temperature rise combustion efficiency,an inlet reference temperature sensor,an outlet reference temperature sensor and a medium temperature sensor with high accuracy are designed,measurementpoint correction factor is proposed and used based on the combination of the outlet reference sensor and medium temperature sensor,and field calibration of the aeroengine temperature rise combustion efficiency is realized.The results show that the adopted temperature rise combustion efficiency calibration method is reasonable,the calibration result is reliable,and the relative deviation between the temperature rise combustion efficiency measured by the reference temperature sensors and computed by the gas analysis combustion efficiency is 0.3%to 2.1%,and thus the method can solve the calibration problem of the aeroengine temperature rise combustion efficiency.
