ABSTRACT:
Disclosed is a parawing with an automatic canopy withdrawing mechanism having a canopy, a frame to which the canopy is fastened and on which a pilot can be carried, a propeller mounted on the frame, and a plurality rows of suspension lines interconnecting the canopy and the frame. Also mounted on the frame is an automatic canopy withdrawing mechanism including a reel which may be operated to pull back the suspension lines for withdrawing the canopy. Further, a front pulling rope interconnecting the reel and two rows of suspension lines near the leading edge of the canopy, a rear pulling rope interconnecting the reel and the trailing edge of the canopy, and a plurality of guide rollers for guiding the movement of the front pulling rope and the rear pulling rope are provided so that the suspension lines and the canopy may be withdrawn by the automatic canopy withdrawing mechanism. With the canopy and the suspension lines being withdrawn. The parawing can be easily steered on the ground free from the possibility of being acted by strong side wind on its canopy. Besides, due to the provision of a rudder at the tail end of the frame, the moving direction of the parawing can be automatically corrected into a direction against the wind when the parawing is acted by a side wind upon take-off so as to avoid the possibility of being upset by the wind. In addition, the provision of the horizontal stabilizer on the frame makes it possible to avoid the pendulum-like motion of the cart and the pilot when the propeller is being accelerated or decelerated during flying. The wheels of the parawing can be replaced by at least one float so that, with the canopy being withdrawn, the parawing can be safely landed on the water surface.
