PSEP Qual, flight acceptance and Qual retest thermal vacuum chamber test report

Abstract

This ATM summarizes test data derived from the PSEP Qualification, Flight Acceptance, and the Qualification Retest and compares these data with analytical predictions. The Qualification Retest was conducted so that an investigation could be made in order to determine the possible causes that could have resulted in the Apollo 11 PSEP over-temperature condition that occurred on the lunar surface following LM Ascent stage liftoff.
