Hy4 – the world's first four-seat passenger aircraft with hydrogen fuel cell technology and electric propulsion
In this manner, the Hy4 marks a milestone. It is a hybrid aircraft with PEM fuel cells and high-performance lithium batteries to support take-off and altitude changes. -
Electric high-flyer for 19 passengers
The configuration represents an electric high-flyer with gas turbines for cruise flight. The conceptual study includes four electric propellers and two gas turbines integrated into the inner nacelles parallel to the electric motors. Batteries are in the landing gear nacelles on the fuselage. -
Conceptual study of a hybrid electric 19-seater
DLR and Bauhaus Luftfahrt analysed the possibilities and potentials of hybrid-electric 19-seaters. The results show that electric drives can be used to save CO2 for short distances of up to 350 km that are frequently flown in this class. -
Conceptual study of a hybrid electric regional aircraft
The conceptual study presents a regional aircraft with distributed electric drives at the leading edges of the wings, which can improve efficiency and reduce energy consumption. Together with industrial partners, DLR is investigating the effects of distributing the propulsion masses over the entire aircraft. -
Hybrid electric short-haul aircraft
An electrically driven fan at the rear of the aircraft ingests the fuselage boundary layer, thereby improving propulsion efficiency. The research work is being carried out in the ADEC (Advanced Engine and Aircraft Configuration) project as part of the European Clean Sky 2 programme.
