Performance of a Boundary Layer Ingesting (BLI) Propulsion System

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
This paper presents an assessment of the performance of an embedded propulsion system in the presence of distortion associated with boundary layer ingestion. For fan pressure ratios of interest for civil transports, the benefits of boundary layer ingestion are shown to be very sensitive to the magnitude of fan and duct losses.
