Abstract : The effects of an Attitude Control Rocket (ACR) exhaust plume include those due to impingement on functional surfaces, and those due to the transmission of electromagnetic signals through the plume. In order to determine the suitability of the selected in-space experiments, a ground test is to be performed on a sub-scale panel. Experiment selection, test panel design, and test plan preparation of this program are reported. The experiments include measurement of the effects of plume temperature, deposition, pressure and emission. Since the experiment is ultimately to be performed in space, all measurements are dynamic, i.e. the experiments have been designed to monitor absolute values and degradations of functional components under actual operating conditions. Also, in order to minimize the differences between the ground test and in-flight test, all panel mounted components are designed for space usage. The major differences to be expected between ground test and space are panel size and readout instrumentation, laboratory instruments being used in the ground test. Emphasis is placed on the Test Plan which serves to tie together the experiment selection, required measurements, and data analysis. Complete descriptions of all components are included and underlying analyses are presented to justify their selection and design.
