Computer Program for Blunt-Nosed Re-Entry Bodies
Abstract
A computer program is given which is one of several that have been created to aid in quickly finding large numbers of solutions to the problem of propagating an EM signal at normal incidence through the plasma sheath upon a wide variety of hypersonic bodies of many sizes and shapes, traveling at speeds of 10,000 to 40,000 ft/sec at altitudes from sea level to 350,000 feet. This particular program, as contrasted to others, developed for slender bodies with sharp pointed noses, is designed for blunt-nosed hypersonic re-entry bodies such as Mercury, Apollo, Dyan Soar, and Aero-Space Plane. The objective of the program is to provide numerical information upon the aerothermodynamic and electronic characteristics of the plasma sheath which extends well beyond the boundary layer into the inviscid flow field on blunt nosed bodies, and to provide unsophisticated numerical estimates of EM signal loss through the plasma sheath in db, due to reflection and absorption, for a plane wave at normal incidence to a single interface model of the plasma sheath.
