DETECTION AND DESIGNATION

Abstract

Two properties of the earth's atmosphere which are pertinent to the description of the phenomenon associated with the reentry of a hypersonic body are discussed. These two properties, density and pressure, are functions of the geometric altitude and vary in a manner which can be approximated by exponential relations. Specific relations for the properties are given for altitudes up to 350 Kft. Since the altitude regime was considered in several increments and the most recent data was utilized i.e., The 1959 Model ARDC Atmosphere, the approximations provide a reasonably accurate determination of the atmospheric property values. In addition, the relations are in a form amenable to in corporation into expressions of motion and aerodynamic heating parameters.
