RÉSUMÉ

Completed in the present work are the calculations of supersonic viscous perfect gas flow over a set of sharp elliptical cones by means of a numerical simulation method [1,2] applied to the experiment conditions [3]. Carried out is the comparison of calculated and experimental local and integral characteristics of cones. The calculated and experimental data prove to be in a good agreement. Discussed is the influence of the angle of attack and of the cross-sectional shape on the behavior of local aerodynamic characteristics of the cone.
