Abstract
Report presenting the low-speed longitudinal stability characteristics of a wing with 45 degrees of sweepback of the quarter-chord line, an aspect ratio of 8, a taper ratio of 0.45, and NACA 63(sub 1)A012 airfoil sections parallel to the air streams investigated in the 19-foot pressure tunnel. Results regarding the basic wing, wing with fences, wing with trailing-edge flaps, wing with leading-edge flaps, a combination of both flaps, fences with the flaps deflected, leading-edge roughness, and the wing-fuselage combustion are provided.
