Boundary layer ingestion integration into aft fuselage

Abstract:

Systems and methods for integrating Boundary Layer Ingestion (BLI) apparatus into an aircraft (1). The longerons (34) in the aft fuselage (18) may be extended to support an aft propulsor (20). The aft propulsor may be a turbofan or turboelectric propulsion system (46). An upper longeron (34a) may support a tail section (14) of an aircraft. The aft fuselage skin (22) is contoured to permit boundary layer airflow to enter an intake fan (24) of the aft propulsor.
