Title: Device for yaw control of ultralight gliders by the action of a floating keel on a moving rudder
IPC: B64C31/028
Filed: 1981-09-14
Abstract: The invention relates to a device for aiding turning of ultralight gliders more commonly known as "hang gliders" piloted by varying the position of the centre of gravity. The ultralight glider consists, on the one hand, of a structure assumed to be non-deformable consisting of two leading edges 1 and 2 of a spar 3 of a wing 4 of a trapezium 5 of a mast 6 and, on the other hand, of a floating keel Q which can move in the plane of the wings 4 around the nose N of the apparatus, able thus to take up two extreme positions 8 and 9 around its mid position 7. On the keel Q is a vertical fin 10 having a vertical rotation axis DELTA passing through the keel at a point C. The peak of the rudder is fixed to the upper rear cable of the glider. When the pilot, who is anchored at A on the keel, moves to the right in the trapezium in order to perform a turn to the right, by this action he drives the keel to position 8. The latter thus moves the rotation axis DELTA of the rudder 10. The front part of the base 11 of the rudder 10 being fastened to the eyelet 12 situated on the median axis 7 of the wing drives the rudder to take up an angle proportional to the angle taken by the keel 8. This position taken by the rudder 10 induces, in flight, a yaw movement sought by the pilot and favourable to the turn. The invention is particularly intended for ultralight gliders and for motorised ultralight gliders.
