ENGINE-AIRFRAME INTEGRATION STUDIES FOR FUTURE EFFICIENT PROPULSION SYSTEMS

Kurzfassung

Aviation is a key part in the complex web of global trade, political, cultural and personal exchanges and the broadening of horizons. Travel & aviation industries were hard-hit by the pandemic, but well on the way to return to pre-2020 growth rates. Increased environmental and societal pressures call for challenging reductions in carbon emissions. Propulsion technology will be core part of technology answer. Several promising engine technologies under study: UHBR turbofans (with geared fans), Open Rotor/Fan engines, Propellers, Distributed (propeller) propulsion, Boundary Layer Ingesting (BLI) engines. Mostly clear propulsive efficiency advantages at engine level. The challenge (aerodynamics and beyond) is the integration of these propulsion technologies with the airframe.
