  • Patent number: 4898377
    Abstract: A roundabout with climbing effect, of the type comprising an airplane designed for a pilot's training and/or recreation, has a pole which is movable in rotation on a vertical axis so as to describe a circular motion on this axis, and is also movable on a horizontal axis so as to enable a variation in altitude of the airplane in the course of its circular motion. A counterweight is provided at the end of the pole opposite the airplane, on the other side of the vertical axis. The airplane is fixed to the pole by a gripping device which cooperates with a circular ring surrounding the fuselage, and which supports the ring and the airplane at the end of the pole while, at the same time, enabling them to rotate freely on the longitudinal axis of the plane, thus enabling the pilot to perform rolls.
