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.

Effects of Boundary Layer Ingesting (BLI) Propulsion Systems on Engine Cycle Selection and HWB Vehicle Sizing

50th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2012
A methodology for analyzing the boundary layer ingestion technology on a hybrid wing body aircraft has been developed using a simplified boundary layer analysis based on computation fluid dynamic results. With certain assumptions, a method for calculating the boundary layer velocity profiles across the flight envelope was shown using a log-wake ...

Hybrid Wing Body Engine Cycle Design Exploration for Boundary Layer Ingesting (BLI) Propulsion Systems Under Design Uncertainty

48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012
of the concept. The current paper presents a modeling approach that allows for the modeling of BLI at multiple design points and throughout the mission operating envelope. Furthermore, the paper presents a probabilistic engine cycle design space study for a 300 passenger HWB aircraft using the EDS design tool that explores the impacts of the various ...
