Popis: In order to solve the problem that the temperature of the compressor outlet air in turbofan engine is not measurable, a method of calculating the static temperature of the compressor outlet air based on the total temperature of the compressor outlet air in the engine bench test data is proposed, according to the principle of aerothermodynamics. And a Simulink model is established. The total temperature, total pressure and design point flow at the compressor outlet of the engine are brought into the Simulink model to calculate. The results show that the static temperature of the compressor outlet at the design point is Ts = 0.9873T*. According to the inverse relationship between temperature ratio function and N2 speed, the linear interpolation is carried out. The relationship between static temperature of compressor outlet and total temperature is T = (1 − 0.0127* N 2)T*.
