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.
An aircraft and a drive device for aircraft comprising a propeller which is driven by a motor, the propeller including blades which can be tilted towards a propeller shaft by way of a joint and in a tilted position pass through a running gap for the propeller formed between a nose of the aircraft and a fuselage by displacement of the nose, the motor being arranged in front of the propeller in a space bounded by the nose.
An aircraft and a drive device for aircraft comprising a propeller which is driven by a motor having a rotor and includes blades which can be tilted towards the propeller shaft by way of a joint and in their tilted-out position pass through a running gap for the propeller formed between a nose and a fuselage of the aircraft by displacement of the nose, and a brake for the rotor and the motor which can be activated by an actuating device for displacing the nose.
An aircraft and a drive device for aircraft comprising a propeller which is driven by a motor, the propeller including blades which can be tilted towards a propeller shaft by way of a joint and in a tilted position pass through a running gap for the propeller formed between a nose and a fuselage of the aircraft by displacement of the nose, the propeller blades being provided with a rotatably mounted setting member that is displaceable and rotatable by way of a setting device.
