Wind-tunnel investigation of a variable camber and twist wingThe longitudinal aerodynamic characteristics of a 35 deg swept, variable camber and twist semispan wing in the presence of a body were studied. The variable camber and twist were incorporated to allow a near optimum lift distribution over the wing for both the cruise condition and the high lift conditions for maneuverability. The wing incorporated movable leading-edge segments whose swept hinge lines provided maximum camber variations at the outboard leading edge and movable trailing-edge segments whose swept hinge lines provided maximum camber variations near the inboard trailing edge. The model was investigated at Mach numbers of 0.60, 0.80, and 0.90 through an angle-of-attack range from 0 deg to 10 deg or buffet onset.
