  • Patent number: 5381988
    Abstract: A tethered model gyroglider having a fuselage, a rotor support extending upwardly from the fuselage, and a unitary two-bladed rotor rotatably mounted onto the rotor support. A teetering mechanism permits the rotor to pivot about an axis proximate the center of the rotor. When the gyroglider is subjected to a relative wind generally from a forward direction, the forward moving blade of the rotor is raised and the rearward moving blade is lowered. This equalizes the aerodynamic forces about the longitudinal axis of the fuselage, thereby eliminating the tendency of the gyroglider to roll in the direction of the rearward moving blade.
