The BERTL (Battery Wing for Regional Electric Transport Aircraft) project is addressing two key aspects of all-electric regional air mobility (RAM), namely battery energy density and aerodynamic efficiency. With an optimised design, a rapid contribution to sustainable aviation can be achieved that fits ideally into the operational and regulatory constraints.
The overall objective of the project is the simultaneous multidisciplinary design of a wing with a high aspect ratio and wing-integrated advanced battery technology. This highly stretched wing design enhances the lift-to-drag ratio, optimizing aerodynamic efficiency. Such a wing design is being explored as a key enabler for the development of fully electric RAM aircraft with 9 to 19 passengers and a range of up to 500 kilometers.
The work of Bauhaus Luftfahrt supports the goal of ensuring the economic viability of the technical concept with special consideration of sustainability aspects. The work therefore focuses on scaling options for an aircraft family concept and initial analyses of integration aspects at airports.
A life cycle assessment of the concept is carried out and the influence of possible alternative battery and recycling options is analysed. The results form the basis of a final overall assessment according to economic and ecological criteria.
The project is funded by the Bavarian Ministry of Economic Affairs, Regional Development and Energy under the funding code HAM-2208-0029.
