The Effect of Rounding the Leading Edges on the Characteristics of Separated Flow Past Delta Wings of Low Aspect Radio

Abstract

The separated flow of an ideal fluid around delta wings of low aspect ratio with rounded leading edges is calculated by an approximation to the theory of slender bodies. The numerical method employed is based upon a mathematical model of inviscid separation from a smooth surface. Results of calculations are given for symmetrical flow around wings whose cross sections are ellipses. Particular attention is paid to the investigation of the influence of the position of the line of separation in the vicinity of the rounded edge of the wing on the configuration of the vortex sheet and to the overall aerodynamic characteristics of the wing.
