Considering the suitability of various engine nacelle models for the propulsion airframe integration of the blended wing body transport, this study employed the Computational Fluid Dynamics approach to compare the engine simulation effects, internal and external flow dynamics, and aerodynamic performance of flow through and powered nacelles. The aerodynamic characteristics of both nacelles when integrated with the airframe were further investigated. The results indicate that the intake mass flow rate is the predominate factor affecting internal and external flow of an isolated nacelle. The influence of the power effect on the airframe surface flow varies greatly under both high and low speed conditions of the installed nacelle. At high speed conditions, the influence of power effect on the airframe surface flow is very small, but the influence is quite great at low speed conditions. To simplify the design process and improve its efficiency, it is recommended to utilize the flow through nacelle in the initial propulsion airframe integration analysis at high speed conditions, subsequently investigating the power effect on the integrated design at both low and high speed conditions.
