Book Description
A free-flight investigation has been made to determine the effect of wing camber and twist at Mach numbers from 1.4 to 2.1 on the lift, drag, and longitudinal stability of a configuration having a 52.5 degree sweptback wing of aspect ratio 3, and inline tail surfaces. The wing was cambered and twisted to have low drag at a wing lift coefficient of 0.3 and at a Mach number of 1.46. The method reported in NACA Report 1226 was used to determine the wing warp. The model was aerodynamically pulsed in pitch throughout the flight of the model alone. Drag polars, normal force, pitching moment, static longitudinal stability, and wash effects at the horizontal tail were obtained. Comparisons are made with data from a similar model that had a flat (untwisted and uncambered) wing.

Book Description
An investigation has been made at Mach numbers of 1.61 and 2.01 to determine the aerodynamic characteristics of three wings having a sweepback of 50 degrees at the quarter-chord line, a taper ratio of 0.20, an NACA 65A005 thickness distribution, and an aspect ratio of 3.5. One wing was flat, one had at each spanwise station an a equals 0 mean line modified to have a maximum height of 4% chord, and one had a linear variation of twist with 6 degrees of washout at the tip. When compared with the flat wing, the effect of the linear variation of twist with 6 degrees of washout at the tip was to increase the lift-drag ratio when the leading edge was subsonic; but little increase in lift-drag ratio was obtained when the leading edge was supersonic. Pitching moment was increased and gave a positive trim point without greatly affecting the rate of change of pitching moment with lift coefficient. For the cambered wing the high minimum drag resulted in comparatively low liftdrag ratios. In addition, the pitching moments were decreased so that a negative trim point was obtained. (Author).
