ABSTRACT:
A glider-canopy has a wing-shaped sail with a rear edge. Fins are mounted to the underside of the sail in an essentially parallel direction to the intended direction of flight. Shroud lines act on at least the fins and converge by their free ends into a personnel support. The fins are equipped with elastically bendable reinforcements tensioning the fins at least under traction from the shroud lines during flight. The fins are tensioned essentially in the horizontal direction so that in the loaded state the sail bulges downwardly at least at the rear edge, and in the event of a load decrease the reinforcements are stress relieved and the sail bulges upwardly at least at the rear edge.
