  • Hang glider having inflatable airfoil
    Patent number: 4116406
    Abstract: A high performance hang glider includes a frame to which is attached flexible sail fabric to create a delta-shaped Rogallo wing. The sail is of double thickness throughout a substantial portion of the wing area to provide an envelope inflatable in flight by air entering an intake opening at the nose of the wing and exhausting through nozzles in the underside of the wing tips. A more efficient double-surface airfoil is thus provided which automatically changes its camber in response to changes in speed for optimum performance.
