Book excerpt: A low-speed wind-tunnel investigation was conducted to study effects of wing-canopy shape on the aerodynamic characteristics and spreader-bar load of a 550 swept parawing having large-diameter leading edges and keel. The canopy-flat-pattern sweep angles investigated on the 550 swept wing were 42.50, 450, 47.50, 500, and 52.50. Several other modifications to the canopy shape were also studied, such as removal of single, double, and compound gores from the rear part of each canopy lobe. A study of the effects of wing-leading-edge sweep angle was made between sweep angles of 500 and 600 and effects of leading-edge diameter were obtained at the basic 550 sweep angle. Effects of keel web height were determined for a constant trailing-edge length and also for trailing-edge lengths that varied with web height.
