Abstract
System studies show that NASA’s N3-X hybrid wing-body aircraft with a turboelectric distributed propulsion system using a mail-slot inlet/nozzle nacelle can meet the environmental and performance goals for N+3 generation transports (three generations beyond the current air transport technology level). In this paper, we present Navier-Stokes flow simulations of N3-X on hybrid unstructured meshes, including the mail-slot propulsor. A novel body force model generation approach is suggested for a realistic and efficient representation of flow turning, pressure rise and losses resulting from the fan blades and the inlet-fan interactions. A new version of mail-slot installation on the N3-X configuration was tested. An optimal shape design of the mail-slot nacelle surface was conducted to reduce the strength of shock waves and flow separations on the cowl surface.
