Boundary-layer ingestion (BLI) and distributed propulsion (DP) are important concepts to future aircraft systems and technologies. Both BLI and DP have the potential to increase aircraft efficiency and improve aircraft design in various other ways. The present study aims to address several design implications and challenges of configuring a BLI, DP aircraft in the highly-compressible transonic environment, which is the aerodynamic regime associated with large, commercial transport aircraft. Aerodynamic shape optimization was performed on two specific propulsion-airframe-integrated airfoil systems, an underwing-propulsor configuration and an overwing-propulsor configuration, to determine the maximum potential performance achievable for such highly-integrated aero-propulsive systems. Preliminary results indicate that the lower surface of a wing may lend itself more naturally to the embedding of propulsors than the upper surface and has the potential for better aerodynamic performance.
