The nacelles and pylons are designed by using an in house tool for engine aircraft aerodynamic integration. the flow field is computed by means of reynolds averaged navier stokes equations. The nacelle can withstand extreme temperatures ( 60°c 600°c), protecting both the engine and the aircraft. the nacelles are painted in the airlines’ colours. the nacelle regulates the air flow at the inlet and the exhaust to ensure optimal engine operation. Cfd numerical simulation method is used in this paper to study in detail the interference effect between propeller slipstream and engine nacelle. by comparing the condition with without propeller, the influence of propeller slipstream on the flow field near the engine nacelle is analyzed.
