Aerodynamic Shaping of a Propulsive Fuselage Concept: A Design Space Exploration

Boundary layer ingestion is an airframe-propulsion integration technology capable of enhancing aircraft propulsive efficiency. The Propulsive Fuselage Concept, a tube-and-wing layout with an rear-fuselage-mounted propulsor in the boundary layer ingestion configuration, especially takes advantage this. However, the relation between physical shape...

Design and Analysis of an Installed Pusher Propeller with Boundary Layer Inflow

Boundary Layer Ingestion is an integrated propulsion concept in which a propulsor operates in boundary layer flow instead of the free streamflow with the goal to reduce the fuel flow for a given operating condition. The objective of this thesis is to obtain a better understanding of the power benefit of an installed pusher propeller at the aft...

Boundary Layer Ingestion: Theoretical and Experimental Research

In this thesis both Wake Ingestion (WI) and Boundary Layer Ingestion (BLI) configurations have been investigated and analyzed with respect to their application to aircraft design. WI and BLI in the context used here means positioning the engine such that it ingests boundary layer fluid for the purpose of saving shaft-power. This research...

Design of Inlet for Boundary Layer Ingestion in a Blended Wing Body Aircraft

Boundary Layer Ingestion (BLI) is a concept in which the fuselage boundary layer is ingested by the engine to produce benefits like improved fuel efficiency, reduction of ram drag and lower structural weight of the configuration. Blended Wing Body (BWB) concept has been researched on and studied in various forms over the years as an efficient...
