Experimental and Theoretical Studies of the Effects of Camber and Twist on the Aerodynamic Characteristics of Parawings Having Normal Aspect Ratios of 3 and 6

Low-speed wind-tunnel studies were made of the effects of camber and twist and the effects of aspect ratio on the aerodynamic characteristics of parawings. To determine the effects of camber and twist, tests were made both with the conventional conical-type canopy, which provides camber and washout, and with a cylindrical-type canopy which provides essentially zero camber and twist. With regard to aspect ratio, tests were made of parawings having aspect ratios of 3 and 6; the range was thereby extended well beyond that of previous investigations. The degree to which airfoil and wing theory can be used to predict the aerodynamic characteristics of parawings was also investigated.
