摘要:
A human powered hang glider has a right main wing and a left main wing, both of which are swingably attached to a post by a universal joint. A rope is stretched in a loop shape between a pedal provided at a lower part of the post and the main wing, and is fixed to the pedal and the main wing. By operation of the pedals, the main wings are flapped like a bird flaps its wing. By this flapping action of the main wings, the hand glider can take wing, whether or not an upcurrent is present.
