초록

A triple mode aircraft which can take off as a helicopter, or in gyrocopter mode with no power to the rotors or as a conventional aircraft obtaining lift from a circular wing and in another embodiment from short stub wings; a canard wing and high lift tailplane. So it combines the flexibility of a helicopter with the same efficiency and safety of a gyrocopter and a fixed wing aircraft, also has the same simplicity and efficiency of flying a helicopter that doesn't have a tail rotor to worry about. The rotor craft includes two counter-rotating rotors with...

청구항

[ What is claimed is:] [1.] In a helicopter main rotor of the type producing lift when rotated about a rotor axis, the rotor including a hub and a plurality of rotor blades radiating from the hub, each rotor blade having an airfoil cross-section for generating lift in response to rotation of the rotor, the improvement comprising:a circular airfoil comprising an annular element with an airfoil cross section mounted on outer ends of the rotor blades, coaxially with the hub for generating lift in response to movement of the rotor in a forward direction tran...
