| description abstract | An investigation at law scale has been made in the Langley stability tunnel in order to determine the effect of linear spanwise variations of twist and circular-arc camber the low-speed aerodynamic characteristics and static-stability and rotary-stability (rolling and yawing) derivatives of a wing of aspect ratio 4, taper ratio O.6, and with 45° sweepback of the quarter-chord line. Results of the investigation indicate that twist or camber produced only small changes in the maximum lift coefficient. A combination of camber and twist was more effective than twist alone in providing an increase in the maximum lift-to-drag ratio in the moderate lift-coefficient range for the investigated. The variation of static longitudinal stability through the lift-coefficient range was less for the twisted wing than for the twisted end cambered plane wing | |
