Extract

The initial structure of wing-body interaction in supersonic flow was first investigated by Nielsen (1951), who analysed the steady supersonic inviscid flow past a proto-type wing-body combination consisting of an unswept thin wing at incidence and lying approximately in the axial plane of a non-lifting cylindrical body with a circular cross-section. In particular, he obtained the first two terms in the series expansion of the velocity potential at the start of the root chord where the wing and body meet. More recently, further theoretical studies which relate the problem to similar problems in diffraction theory have been carried out by Stewartson (1966), Jones (1967), Waechter (1969), and Clark (1970). In addition, Stewartson (1968) has extended Nielsen's formula for the following cases:

(a) the lifting wing with rounded leading edge,

(b) the flat plate wing at incidence with supersonic leading edge,

(c) the flat plate wing at incidence with subsonic leading edge in both symmetrical and antisymmetrical cases.
