Abstract
A previously developed unsteady embedded Newtonian theory has been ext ended to be able to predict the hypersonic unsteady aerodynamics of ax isymmetric bodies of general shape with the accuracy needed for prelim inary design. The static aerodynamics determined by a three-dimensiona l finite difference method are used together with unsteady embedded Ne wtonian flow concepts to provide the vehicle dynamics without signific antly adding computational time to the static computer program.
