Applying Boeing Commercial Airplane automated test and checkout techniques to reusable space propulsion systems

Automated test and checkout computer tools that have been developed for commercial and military aircraft are presently shown to be applicable to reusable launch vehicle and spacecraft propulsion systems, for the sake of reductions in maintenance personnel and calendar time. Attention is given to the potential uses of the Programmable Engine Tester and the Integrated Functional Test System in the context of SSME problems. It is found that while direct application of existing automated checkout systems would be difficult, future spacecraft propulsion technology can be designed for integral operation with such systems.
