The three-dimensional supersonic flows (M = 2 - 4) about the wings (delta and variable sweepness wings) as well as lifting bodies with sharp and blunt, sub- and supersonic leading edges are considered. The specific regimes and flow field structure are analyzed on a basis of existing experimental data and the capabilities of their numerical modelling in a framework of Euler equations are demonstrated. The validity limits of this approach for the flow field structure and aerodynamic characteristics predicting are discussed as well as possible reasons of the numerical and experimental data discrepancy are analyzed.
