STUDY TO OBTAIN DESIGN DATA FOR REENTRY ECM ANTENNA SYSTEMS

Abstract

This report presents survey material on the effects of the reentry environment on the voltage breakdown characteristics of antennas. Most of the important effects are fairly well understood in that theoretical models exist and experimental data are available in sufficient quantity to allow predictions to be made with confidence. However, the effect of high gas temperature is not sufficiently understood, although recent experimental data have indicated a mechanism which may prove to be important in controlling breakdown. This mechanism is strongly dependent on vibrational excitation and dissociation of the gas molecules. The problem of predicting the vibrational excitation state in a hypersonic flow field is not presently possible in a detailed microscopic analysis, but an approximate solution is possible.
