The analytical models developed for the Space Propulsion Automated Synthesis Modeling (SPASM) program are presented. Weight scaling laws developed during this study are incorporated into the program's scaling data bank. A detail listing, logic diagram and inputoutput formats are supplied for the SPASM program. Two test examples for one to four-stage vehicles performing different types of missions are shown to demon strate the program's capability and versatility. (Author)
