摘要

The aircraft drive system has an electric motor (1), a storage arrangement (2) and an airscrew (3-5) that can be used as a propeller and as a rotor. The propeller drives the aircraft and the rotor is used to feed back energy. The airscrew is changed between the propeller and rotor functions by adjusting its blades (3,4).
