The design and installation angle optimization of the engine nacelle for the civil turboprop aircraft considering the influence of propeller slipstream is completed. A detailed computational evaluation is conducted, and the interference mechanism between the slipstream flow, the nacelle and wing is analyzed.The results show that the lift to drag ratio of the aircraft can be greatly improved by 2%.
