Aircraft

Abstract

An aircraft, comprising an internal combustion engine by whose drive power a propeller can be driven, wherein the internal combustion engine cooperates with an electric machine which in a first operating mode is operable as electric motor and in a second operating mode as electric generator.

Description

technical field [0001] The invention relates to an aircraft comprising an internal combustion engine, the drive power of which can drive propellers. Background technique [0002] In aircraft powered by internal combustion engines, mainly gasoline engines, diesel engines or two-stroke engines are used. During certain phases of flight, these internal combustion engines need to be run at increased power. For example during take-off of the aircraft or in a safety-critical climb phase following take-off, it is thus necessary to generate a surplus power. However, internal combustion engines are operated at particularly high rotational speeds and loads, whereby wear also increases disproportionately. [0003] In addition, aircraft are known which are driven exclusively by electric motors. DE 195 12 816 A1 proposes a glider with an auxiliary motor comprising an electric motor, wherein the energy supply of the electric motor is ensured by battery arrangements arranged in the wings...
