  • Articulated drive
    Patent number: 6467724
    Abstract: An aircraft has a fuselage designed essentially as an aerostatic lift body and combined lift and propulsion devices which are articulated on the fuselage, are provided with propellers and form propulsion units and which in each case are tiltable between a lift position, in which the respective propeller rotation plane is essentially horizontal and the output shaft of the associated drive, said output shaft acting on the respective propeller shaft, is essentially vertical, and a propulsion position, in which the respective propeller rotation plane is essentially vertical and the output shaft of the associated drive, said output shaft acting on the respective propeller shaft, is essentially horizontal. The propeller rotation plane has all-round inclinability relative to the output shaft of the associated drive, said output shaft acting on the propeller shaft.

  • Aircraft with a fuselage substantially designed as an aerodynamic lifting body
    Patent number: 6286783
    Abstract: An aircraft has a fuselage designed essentially as an aerostatic lift body. Combined lift and propulsion devices are articulated on the fuselage, are provided with propellers and form propulsion units and which in each case can tilt between a lift position, in which the respective propeller rotation plane is essentially horizontal and a propulsion position, in which the respective propeller rotation plane is essentially vertical. Additionally the propeller rotation plane has all-round inclination relative to the output shaft of the associated drive device.
