ABSTRACT:
A flying craft has a supporting element with an opening in it. A driving unit with a propeller drives air downwardly through the opening. Vanes mounted on the driving unit break up the circular component of the air velocity and also counteract the torque on the driving unit. The downwardly moving air is formed into a laminar air stream by a second set of vanes which are connected to the supporting element for rotation therewith. The pitch of the vanes can be adjusted. Adjustment of the pitch of the second set of vanes may cause the supporting element to rotate and give the craft a gyroscopic stability. The craft is tiltable for maneuvering purposes.
