THE DETERMINATION OF HYPERSONIC DRAG COEFFICIENTS FOR CONES AND SPHERES

Abstract

Analytical expressions have been developed for determining drag coefficients for cones and spheres. An error analysis is presented in which the resulting drag equations are compared to wind tunnel and ballistic range data, and some limited flight test data. Also presented are the results of an investigation aimed at determining the altitude range where a conical or spherical re-entry vehicle will undergo boundary layer transition.
