ABSTRACT:
The invention concerns the forming of vertical thrust by rotor blades and their subsequent stopping to act as wings, by changing the angle of of attack of the individual stationary blades during foward flight. The horizontal movement of each blade is independent from one another around the perimeter of the central rotor axis hub, and the opposing diagonal set's move up against each other and interconnect to become an integrated single wing from the two separate blades. A common pivot is utilized across the intersecting edges of the blades comprising the singular wing to have this common pivot hinge between them to allow changes in pitch of the leading and trailing parts of the wing. Such joined blades acting as wings are able to move together to accomplish a variable swing wing movement that would include swept foward and back configurations and infinite changes of their attitude between those two extreme positions.
