Abstract
Report presenting an investigation in the high speed 7- by 10-foot tunnel to determine the effects of a spanwise variation in thickness ratio on the aerodynamic characteristics of a wing with a plan form identical to that of a constant-percent thickness-ratio wing program. The wing with thickness variation had 35 degrees of sweepback, aspect ratio 4, and taper ratio of 0.60 with airfoil section tapered from an NACA 65A006 section at the root chord to an NACA 65A002 section at the tip chord. Results regarding the lift characteristics, drag characteristics, and pitching-moment characteristics are provided.
