A rotor system that allows an aircraft to operate as a helicopter and as an airplane is disclosed. The invention incorporates an annular airfoil attached at the tips of the rotor blades. The rotor system stops and is secured from rotation for operation at high forward speeds. The annulus acts as the primary lifting surface in airplane mode at high speed. The rotor blades incorporate leading and trailing edge flaps for control in transitional and fixed wing flight modes.
1. A rotary/fixed wing aircraft, comprising:a single annular wing with articulating rotor blade wings extending radially from a rotating hub to said annular wing, each of said articulating rotor blade wings comprising an edge flap, said annular wing configured to tilt with said blades when said blades are articulated; a first control system for controlling the aircraft in rotary, helicopter mode; a second control system for controlling the aircraft in fixed wing, airplane mode; a locking mechanism for preventing the rotation of said rotor blade wings whe...
