Langley Full-Scale-Tunnel Investigation of Maximum Lift and Stability Characteristics of an Airplane Having Approximately Triangular Plan Form (DM-1 Glider)

Abstract

Glider having an aspect ratio of 1.8 and 60 deg swept-back leading edge was tested to determine effects that various modifications had on lift and stability. Maximum lift coefficient was increased from 0.61 to 1.01 by installation of semispan sharp leading edges and from 1.01 to 1.24 removal of vertical fin and sealing of eleven control-balance slots. Results also indicated that airplanes with such plan form can be designed to have acceptable stability characteristics in subcritical speed range.
