REINFORCED GRAIN ADVANCED DEVELOPMENT PROGRAM
Abstract
The program originally outlined the development of three designs of lightweight, upper-stage motors using wire as grain reinforcement. Eventually, one of the original three upper-stage designs was replaced by a testweight air- launched demonstration motor with extreme environmental requirements. One of the upper-stage designs included a supersonic split-line gimbaled nozzle. Static firing test results of the upper-stage motors showed the design approach yielded high mass fraction goals. However, fabrication experience proved that unusual care and development approaches were necessary. Limitations and areas of risk, as well as preferred approaches, were established from the wide range of tests conducted during this Advanced Development Program.
