Effects of Different Flow Field Conditions on the High Power Transmission Properties of a Reentry Plasma.
Abstract
The computer program for calculating the high power microwave transmission coefficients of a chemically seeded reentry plasma has been described in two previous reports by the author. It has been explained how the computer code can optimize the amount of high power that can be transmitted from a reentry vehicle. The injection of electrophilic compounds into the reentry flow field can suppress the onset of antenna voltage breakdown, so that the transmitted power can be greatly increased. Using a half implicit-half explicit time integration scheme, the electron and ion transport equations coupled with Maxwell's equations are numerically integrated to determine the nonlinear reflection and transmission coefficients of a reentry plasma. Corresponding to the flow field conditions of a blunt nosed reentry vehicle (Trailblazer 2), graphs are presented to the electron density profile and plane wave reflection and transmission coefficients.
