Performance of a Single-Aisle Aircraft with Auxiliary Propulsion and Power Unit

The aviation industry has grown at a steady rate of 5% per year over the past decades and is projected to continue this growth over the coming years. In sharp contrast stands the increasing concern with the reduction of the environmental impact of flying in the short term. To this end, a fuselage boundary layer ingesting propulsor powered using...

Development of a Hydrogen-powered Fuselage-mounted BLI Propulsor Add-on for Passenger Aircraft

The concept of an "Auxiliary Power and Propulsion Unit" (APPU) is introduced, which consists of a Boundarylayer ingesting (BLI) propulsor with an engine mounted at the rear of an passenger aircraft fuselage, replacing the Auxiliary Power Unit (APU) and contributing around 10% of total cruise thrust, as well as auxiliary power. This APPU unit is...
