Investigation of Wing Characteristics at a Mach Number of 1.53. 3 - Unswept Wings of Differing Aspect Ratio and Taper Ratio

Abstract

Wind-tunnel tests were conducted for seven unswept wings varying in aspect ratio from 1 to 6 and in taper ratio from 0 to 1 at a mach number of 1.53 and a Reynolds Number of 0.75 million. All wings had an isosceles triangle section 5-percent thick. The experimental results were compared with the predictions of linear theory. The aerodynamic parameters generally varied with aspect ratio and taper ratio in the manner indicated by the linear theory. The measured values of the lift-curve slope were in accord with the theoretical values for all the wings, but the experimental angles of zero lift were consistently higher than those given by linear theory.
