APPU

The APPU project

The EU Flight Path 2050 Goals aim at dramatically reducing the climate impact of aviation. While drastic changes in the aircraft configuration are only possible in the latter half of this century, the climate impact of aviation has to be tackled soon. The APPU project aims at significantly cutting local air emissions while significantly reducing the global impact of aviation by introducing “Energy Mix” into aviation and enhancing aircraft efficiency by application of novel boundary layer ingestion (BLI) technology to the workhorse of aviation, the A320, thereby reducing the risks and the time to market introduction drastically. The proposed APPU is a novel system that replaces the traditional APU with a multifunctional state of the art gas turbine fuelled by Hydrogen and powering a variable pitch open rotor propulsion system at the aft end of the fuselage in a BLI configuration.
