Abstract
Experimental forces and moments for two wing-body combinations having a) a swept wing and b) an oblique wing are compared. At all Mach numbers, the oblique wing (at its optimum sweep angle) had higher maximum lift-to-drag ratios than the fixed, swept wing. At high angles of attack, the direction of the pitching or rolling tendencies of the oblique wing was a function of the spanwise distribution of wing bend or washout for the two bends being investigated. At low angles of attack, linear theory gave satisfactory predictions of the subsonic liftcurve slope, the aerodynamic-center travel with Mach number, and the maximum lift-to-drag ratio.
