Abstract
In order to provide a compact, high-performance drive device for aircraft, in particular for power gliders, which comprise a propeller which is driven by a motor, preferably by an electric motor, and the blades (6) of which can be tilted towards the propeller shaft (15) by way of a joint and in the tilted-out position pass through a running gap (5) for the propeller formed between the nose, in which the generally minimal conditions of space are utilized in an optimum manner and which ensures the necessary aerodynamic properties of the aircraft, the invention proposes that the motor (10) should be arranged in front of the propeller in the space bounded by the nose (4). In this way, the interior of the aircraft as far as the running gap (5) for the propeller is made available for the pilot or the aircraft passengers, so as to ensure optimum use of the said interior and the length of the aircraft can be kept short.
