초록

A VTOL aircraft having a fuselage with fixed ring wings on either side thereof. Each ring wing has a rearwardly extending nacelle associated with it. Each nacelle has a ring tail empennage at its after end and a propulsor fan in its nose operating in the bore of its associated ring wing. The propulsor fans provide propulsion thrust for conventional flight in which the flow created over the lifitng surfaces due to forward velocity of the aircraft generates lift for flight. The propulsor fans operate to induce a flow over the lifting surfaces to generate l...
