On Three-Dimensional Structure of Transonic Flows,

Abstract

The basic structure of three-dimensional transonic flows past lifting configurations having finite leading-edge swept angles are studied. Unlike the axisymmetric structure following the transonic area rule, the inviscid transonic small-disturbance regime admits three principal domains, representing different degree of asymmetry controlled by the lift and side forces. An outline of the basic theory and a transonic equivalence rule that follows are presented; the implication of this research to other transonic studies related to far-field properties and to flow field computations are discussed. The possibility of an extension and application to yawed critical wings is pointed out. (Author)
