The FREA project (Flügel für Regional Electric Aircraft / Wing for Regional Electric Aircraft) is dedicated to enabling sustainable regional aviation with all-electric aircraft for distances up to 500 km. The focus lies on technical validation, industrialization, and real-world operation of a newly developed wing design.
At the core of FREA is a multidisciplinary approach to optimize wing design. By integrating the battery directly into the wing structure, weight is minimized, while the high-aspect-ratio wing enhances aerodynamic efficiency through an optimal lift-to-drag ratio. This innovative design ensures maximum energy efficiency while aligning with operational and regulatory constraints, paving the way for a rapid contribution to sustainable Regional Air Mobility.
Our goal is to provide a better understanding of the technical, economic and ecological potential of all-electric regional aircraft in general and for the concept of a battery-integrated high aspect ratio wing in particular.
The work focuses on:
- the identification of relevant deployment scenarios,
- the definition of airport infrastructure requirements,
- a life cycle assessment of alternative battery and recycling options,
- as well as the overall ecological and economic evaluation of the technical concept by comparing a conventional baseline aircraft with full-electric and other alternative fuel-powered aircraft.

The project is funded by the Federal Ministry for Economic Affairs and Climaty Action of Germany under the funding code 20M2252B.
