SUPERSONIC DRAG OF SLENDER BODIES IN A SIMPLE DIATOMIC DISSOCIATING GAS

Abstract

Quantitative results of linear slender-body theory are treated. The drag of two cases is considered; a circular cone and a parabolic spindle. The extra drag due to nonequilibrium effects turns out to be appreciable in one case. For the case of the circular cone, the extra drag is positive, while for the case of the parabolic spindle, the extra drag is negative indicating that the nonequilibrium effects decrease the total drag.
