The present invention herein is a disc shaped wing comprised two disc segments, an inner disc assembly and an outer disc assembly, that counter-rotate to enable vertical take off and landing. The inner disc assembly has a plurality of flap blades that open to provide lift during take off and landing and close to provide a substantially contiguous surface during horizontal flight. The outer disc assembly has a plurality of lower blades that contain retractable blades. During take off and landing the retractable blades extend to provide added lift and stab...


1. A counter rotating wing for an air vehicle having a circular shape comprising:an inner disc assembly and a counter rotating outer disc assembly, said inner disc assembly and said outer disc assembly secured about a central drive shaft assembly; said drive shaft assembly having a top end and a bottom end, said bottom end engaging a power source; said drive shaft assembly comprising a plurality of coaxial counter rotating drive shafts; said inner disc assembly, having an inner disc hub, an inner disc ring, and a plurality of support rods spaced an equal...
