Abstract : The exact 'constant-energy' solution of strong blast waves is expanded in powers of the density ratio across the shock wave; physical quantities are expressed directly as functions of the similitude parameter. The range of validity for t.;e application of this solution to hypersonic flow is then studied as a function of the density ratio. The general similar solution of the strong blast wave is found in the Newtonian approximation. The results are applied to power-law bodies in hypersonic flow using the equivalence principle. The pressure distribution on slender bodies of arbitrary shape is obtained and agrees with the Newton-Busemann pressure formula. Higher-order approximations are derived for the cases in which the shock layer is thin. A simple pressure formula is obtained and some of its applications are shown. (Author)
