Full-Scale Investigation of the Maximum Lift and Flow Characteristics of an Airplane Having Approximately Triangular Plan Form

Abstract

Procedures leading to use of sharp leading-edge wings to improve maximum rift coefficient are presented along with discussions of aerodynamic phenomena involved and curves showing aerodynamic characteristics of DM-1 glider. Airfoils with sharp leading edges, or small leading edge radii, will have satisfactory low-speed characteristics when used with highly swept-back wings. Flow over triangular wings is characterized by vortexes over wings, inboard of tips. High lift/drag ratio produces prohibitive power-off glide angle.
