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.
