A numerical simulation based on CFD-DPM model has been constructed to consider the dynamic effect of the sands in the airflow on the total pressure recovery coefficient and distortion rate of the inlet. The propeller slipstream has also been calculated to evaluate the influence on the inlet performance with sands, and the influence law of the parameters of the sands have been further revealed.
