发明名称 Counter rotating circular wing for aircraft
摘要 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 stability. The wing shape and counter-rotation also imparts greater stability and lift for horizontal flight.
