Power Balance Analysis Experiments on an Axisymmetric Fuselage with an Integrated Boundary-Layer-Ingesting Fan

Boundary Layer Ingestion (BLI) is a promising propulsion integration technology capable of enhancing aircraft propulsive efficiency. The Propulsive Fuselage Concept (PFC), tube-and-wing configuration with an aft-fuselage-mounted BLI propulsor, particularly suited for BLI. Although extensively studied on system level, the aerodynamic performance PFC, resulting from complex interaction between airframe and still largely uncharted. In this paper, results wind-tunnel tests simplified PFC model are presented. featured axisymmetric fuselage body integrated shrouded fan. Flowfield measurements were performed through particle image velocimetry to analyze key phenomena assess distribution momentum mechanical energy around aft-fuselage propulsor. Results show that fan alters surrounding flowfield by increasing mass flow in inner part boundary layer reducing boundary-layer thickness. Moreover, power analysis indicates potential benefit strongly dependent setting. Increasing shaft leads higher amount dissipated near wake. However, share flux associated excess contained
