Abstract

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.
