Concept and design of a high power dense propulsion system for electric aircraft

Mostrar todas las versiones(2)

The present thesis proposes a conceptual design of a tiltable propulsion system for the ALBACOPTER® 1.0, an eVTOL aircraft with a take-off mass of800 kg. Usually, the propulsion systems of eVTOLs are direct drives due to their simple design. However, since the propeller thrust in relation to the tak...
