THEORETICAL AND EXPERIMENTAL ANALYSIS OF LONGITUDINAL AND LATERAL AERODYNAMIC CHARACTERISTICS OF SKEWED WINGS AT SUBSONIC SPEEDS TO HIGH ANGLES OF ATTACK
This paper presents a theoretical and experimental analysis of the aerodynamic characteristics of low-aspect-ratio skewed (oblique) wings having separation-induced vortex flows along leading and side edges. The purposes of this investigation were to determine the effects of sweep and aspect ratio on the longitudinal and lateral-directional aerodynamic characteristics of these wings and to compare experimental results with asymmetric, separated, vortex-flow theory. The theoretical analysis used the vortex-lattice method for estimating attached-flow aerodynamic character¬istics and the leading-edge suction analogy of Polhamus for estimating separation induced vortex-flow effects. The experimental results were obtained in the Langley high-speed 7- by 10-foot tunnel at a low-subsonic Mach number.
