The Effects of Sideslip, Aspect Ratio, and Mach Number on the Lift and Pitching Moment of Triangular, Trapezoidal, and Related Plan Forms in Supersonic Flow
Abstract
The variations of lift and pitching moment with side slip in supersonic flow have been calculated for a representative group of plan forms. The variations of lift and pitching moment with aspect ratio and Mach number at zero side slip were also investigated. The analysis was based on linearized potential theory and was applied to triangular, trapezoidal, rectangular, and sweptback plan forms without dihedral. In general, the lift and pitching moment showed a slight but steady increase in magnitude as the side slip angle was increased. For a fixed Mach number, the only decrease in lift or in the magnitude of the pitching moment with increasing aspect ratio was the decrease in the latter parameter for the trapezoidal plan forms with raked -out tips. With the aspect ratio fixed and Mach number increasing, the only increases in either of these parameters was in the magnitude of the pitching moment for the sweptback plan forms.
