Forces and Pitching Moments on an Aspect-ratio-3.1 Wing-body Combination at Mach Numbers from 2.5 to 3.5 and Sublimation Studies of the Effect of Single-element Roughness on the Boundary-layer Flow

Edward J. Hopkins, Stephen J. Keating, Richard R Muhl

Abstract

Report presenting lift, drag, and pitching-moment characteristics for a wing-body combination for a range of Mach numbers. The wing had an aspect ratio of 3.1, a sweepback of the leading edge of 19.1 degrees, a taper ratio of 0.39, and a biconvex profile with a thickness of 3 percent of the chord. Results regarding aerodynamic characteristics and visual-flow studies are provided.
