Abstract

Modern supersonic/hypersonic gas dynamics employs localized interaction models that determine projectile-fluid interaction at any location on the projectile as a function of a local inclination of its surface to the freestream flow and global parameters. A method is developed implying the local character of projectile-fluid interaction but does not require specification of the model and its parameters. Aerodynamic characteristics of a projectile are found by recalculation of the known characteristics for several basic projectiles that are determined either experimentally or with an exact model for the same flight conditions. The localized interaction model for all of these projectiles is considered to be the same although unknown.
