Vertical take-off and landing (VTOL) aircraft with fixed horizontal variable-pitched rotors

Claim 1

In a vertical take-off and landing aircraft, the combination of a jet airplane including a fuselage and sideward wings, a turbojet engine for horizontal flight, a circular opening vertically through a midportion of each said wing, a rotor assembly positioned in each said opening being rotatable about a generally vertical axis, each said rotor being individually controlled and powered by an engine, including transverse struts supporting said engines axially above said rotors, said struts extending laterally from opposite sides of said fuselage parallel to and spaced above said wings, each said rotor including a plurality of radially extending blades pivotally controlled about a radially extending axis from a hub of said rotor, and means being provided to prevent stress of said blades from air during forward flight, said rotor blades providing vertical thrust during takeoff or landing of said airplane, wherein said means comprise transverse similar ailerons mounted along forward edges of each wing, said ailerons including upper and lower fins pivotally controlled about hinges along their forward edges hinged to upper and lower surfaces of said wing, said ailerons being of such length so as to deflect air from contact with the entire rotor assembly having a closed streamlined front edge diverging rearwardly to align with upper and lower surfaces of the wings.
