Design and Analysis of an APU Monopropellant Gas Generator

The performance, mechanical integrity, and operational characteristics of a monopropellant thermal gas generator have been predicted using analytical tools developed through the use of digital and analog computer programs. The basis for these analyses are empirical relationships derived from experiments, as well as theoretical relations. A throttleable prototype gas generator has been designed and fabricated to meet the requirements of an APU for use in the Space Shuttle vehicle.
