Effects of Leading-edge Chord Extensions and an All-movable Horizontal Tail on the Aerodynamic Characteristics of a Wing-body Combination Employing a Triangular Wing of Aspect Ratio 3 Mounted in a High Position at Subsonic and Supersonic Speeds

Benton E Wetzel, Frank A Pfyl

Abstract

Report presenting the results of an experimental investigation of the effect of leading-edge chord extensions on the aerodynamic characteristics of a wing-body-tail combination employing a 3-percent-thick triangular wing of aspect ratio 3 in conjunction with an unswept, all-movable, horizontal tail located below the wing-chord plane. Lift, drag, pitching moment, and hinge moment were measured a range of Mach numbers and a constant Reynolds number.
