The rotors of a helicopter are driven by electric machines. The electrical energy required therefor is generated by a motor-generator unit (101, 103) which comprises one or several combustion engines (100). The motor-generator unit may be disposed below the cabin floor. In this way, a hybrid helicopter is provided in which the rotation frequency of the rotors can be adjusted within a large range.
