Effect of aspect ratios of 2, 3, and 5 and sweepback angles of 0 Degrees, 30 Degrees, and 45 Degrees on the aerodynamic characteristics of a NACA 65-110 airfoil, with two-inch chord was investigated. Mach range was from 0.40 up to choking (0.870 - 0.960). Section characteristics were also determined. Sweepback and low aspect ratio each tend to delay and lessen compressibility effects. When in combination, effects of sweepback and low aspect ratio are cumulative but less than additive.
