Wind tunnel tests on cambered wings of mild gothic planform part 1 further low-speed tests part 2 transonic tests

Abstract

Measurements are reported of the longitudinal characteristics of seven wings of mild gothic planform, aspect ratio 1.4, sharp leading edges, and two different thickness ratios. Five of these were cambered to keep the flow attached at the leading edges at lift coefficients of 0.1 or 0.2 The remaining two were symmetrical. Transition was fixed artificially, so preventing separation further downstream on the cambered wings. All the wings were tested at low speeds and the results complement the transition-free data on three of the wings in ARC CP No.1163. Transonic testing covered a range of Reynolds and Mach numbers on a representative cambered wing.
