Aerodynamic Characteristics of Two 25-percent-area Trailing-edge Flaps on an Aspect Ratio 2 Triangular Wing at Subsonic and Supersonic Speeds

John W. Boyd

Abstract

Report presenting the results of an investigation of flap-type controls on a low-aspect-ratio triangular wing using NACA 0005-63 sections for a constant-chord and a constant-percent-chord control surface. Two flap profiles were investigated: one with a true contour and the other with a blunt trailing edge. Results regarding lift, drag, pitching moment, hinge moment, and rolling moments were obtained for several Mach numbers, a constant Reynolds number, and a range of angles of attack.
