Scalability and limitations of Hybrid Electric concepts up to large commercial aircraft

Radical aircraft concepts with green enabled propulsion systems are being developed for several vehicles classes (small, regional and large aircraft). Certain switch points are existing were technologies are better suited to one or another class, also in the frame of different regulatory frameworks. These switching points substantially influence the requirements with respect to the main features of the aircraft architecture, with substantial effects on economic figures for the entire industrial lifecycle, also achievable reliability and safety levels. In the frame of this studies there need for different approaches or the opportunity for common approaches should be defined. Please refer to the full topic descriptions document published in this call.
