Physically Active Fire Extinguishing Materials as Replacements for Halon Agents in Aircraft Systems

The banning of Halon fire extinguishing agents has seriously compromised the effectiveness of fire protection for a number of applications where they have been the 'universal' choice, especially on-board aircraft in habitable areas and 'fire zone' areas. Efforts have been underway by the chemical industry and various government agencies for the development of suitable alternative 'chemically' acting agents. Thus far, candidates offer significantly reduced effectiveness (average +75% weight penalty), higher cost and ill-defined toxicologic properties. This Phase I program focuses on the development of 'physically' acting fire extinguishing materials which can replace Halons 1301 and 1211 for fire zone applications and Halon 1211 for the on-board first-aid fire extinguisher application. The Phase I program includes: inert gas generation materials and techniques; formulation of non-acqueous foam agents; and comparative performance analysis versus the standard Halons. A final report will document all activities and summarize near-term advanced development and future commercialization opportunities. Key personnel on the program possess unique, extensive and direct experience with a myriad of aerospace fire protection areas including research and development on fire extinguishing agents and systems for aircraft engine and other compartments and engineering of engine nacelle fire test simulators.
