ABSTRACT

The flow in a spatial boundary layer in the vicinity of the plane of symmetry of a semi-infinite flat delta wing in the regime of a strong viscous-inviscid interaction is investigated. For the case of a finite-span wing, the stream functions are expanded into a power series in the transverse coordinate. A boundary-value problem for the principal terms of the expansion is studied, and the effects of the temperature factor and the sweep angle of the leading edge on the solutions obtained are considered.
