Aerodynamic Characteristics of Tapered Wings Having Aspect Ratios of 4, 6, and 8, Quarter-chord Lines Swept Back 45 Degrees, and NACA 63(sub 1)A012 Airfoil Sections : Transonic-bump Method

Edward C Polhamus, Thomas J. King

Abstract

Report presenting testing of a series of three wings over a range of Mach numbers by the use of the transonic-bump technique. The lift, drag, pitching-moment, and root-bending-moment data of wings of a variety of aspect ratios but with the same quarter-chord lines and airfoil sections were obtained.
