ABSTRACT

This paper presents a numerical simulation of supersonic flow around a vehicle with various noses (hollow cylinder, cone, and spherical bluntness) and the same tails (cylinder-conical stabilizer). Analysis of flow fields and space distributions of the gas-dynamic parameters in the flow and on the surface of the considered configurations is carried out. The calculated results and the experimental data are compared. The features of supersonic flow concerning the aerodynamic drag of a configuration that has a truncated cone as a stabilizing device are considered.

KEY WORDS: supersonic flow, axisymmetrical flow, conical stabilizer (flare), flare semi-apex angle, hollow cylinder, spherical bluntness, wave drag
