Solid Propellant Gas Generators: Proceedings of the 1995 Workshop (NISTIR 5766)



Jiann C. Yang, William L. Grosshandler


A workshop on solid propellant gas generators was held on June 28-29, 1995 at the National Institute of Standards and Technology under the sponsorship of the Building and Fire Research Laboratory. Gas generator technology was first proposed as alternative to halon 1301 (CF3Br) for in-flight fire protection. Because the technology is still in a developing stage as a fire suppression method, there is no standard test apparatus for evaluating the performance of gas generators, and there remain many unanswered technical questions for the potential users. The specific objectives of the workshop were (1) to identify certification procedures, (2) to determine which critical parameters were required to characterize the performance of a gas generator, (3) to develop a standard test method for gas generator evaluation, (4) to identify other potential applications, and (5) to search for next generation of propellants. The participants at the workshop included representatives from aircraft and airframe manufacturing industries, airbag and propellant manufacturers, fire fighting equipment companies, military services, government agencies, and universities. The agenda of the workshop encompassed eleven presentations on various topics relevant to the applications of gas generators as a fire fighting tool, followed by several discussion sessions. Various important issues related to the achievement of the objectives set forth were addressed, and recommendations regarding what role NIST should play in this new technology were suggested.
