There is a strong aerodynamic interference between the propeller and the intake under working conditions,which has a certain impact on the propeller and the intake.In order to explore the interaction between the two,this paper used the three-dimensional numerical simulation method of internal and external flow integration to carry out the simulation study of propeller and intake matching for a turboprop engine,especially the interaction between propeller performance and the characteristic parameters of the intake outlet section,which provide useful theoretical support and basic methods for the design and optimization of the subsequent propeller and intake.The results show that the numerical simulation method adopted in this paper has high confidence in the calculation of propeller performance,which basically meet the requirements of three-dimensional simulation of propeller;the interaction between the propeller and the intake mainly affect the intake:the DC60 of the intake outlet section is affected by the incoming Mach number,the propeller speed and the intake outlet pressure,and it decreases with the increase of the incoming Mach number and increases with the increase of the propeller speed and the intake outlet pressure.
