Embodiment 1
[0037] The present invention determines the calculating method of ambient temperature upper limit in aircraft nacelle, its flow process is as follows figure 1 shown, including the following steps:
[0038] Step 1: Obtain the average temperature of the engine surface
[0039] like figure 2 As shown, according to the core components of the engine, the engine is divided into four sections along the axial direction. The surface temperature of the engine casing is obtained from the engine test, and the average surface temperature T of each section of the casing is obtained respectively. n ,like image 3 As shown, the temperature of each section is expanded as follows: Compressor section T 1 =316K, combustion chamber section T 2 =361K, turbine section T 3 =366K, nozzle section T 4 =373K; take the maximum value T w =T 4 = 373K;
[0040] Step 2: Determine the temperature extremes of the aircraft operating environment
[0041] According to the actual working conditions of th...
