Knowledge of the frontal flow field is a necessary prerequisite to an understanding andor analysis of a bodys reentry characteristics. It is the purpose of the report to provide preliminary estimates of such flow fields for a slender, pointed cone traversing the earths atmosphere at hypersonic velocities. The analysis is divided into two parts the inviscid portion of the shock layer and the boundary layer. Estimates are made of the thermo and hydrodynamic characteristics of each throughout the critical phase of reentry. Eleven specific flight conditions are considered corresponding to 25 kilofeet increments between 50 and 300 kilofeet altitudes. The results are presented in both tabular and graphical forms. Author
