Assessing the Impact of the Inlet Total Pressure Distortion on the Turbofan Thrust
Mechanical Engineering and Computer Science, 2018 The paper considers techniques to develop a mathematical model using a method of «parallel compressors». The model is intended to estimate the impact of the air inlet distortion on the primary parameters of the aero-engine. The paper presents rated estimation results in the context of twin spool turbofan design for two typical cruiser modes of flight ...
