Dry chemical fire extinguishing agents were studied in a simulated small scale aircraft engine nacelle environment to observe the ability of these agents to prevent re-ignition a known deficiency of the presently used gaseous agents. An injector was developed which effectively dispersed agent into the airstreams; a fuel spray behind a flameholder, ignited and sustained by a hot surface, was used as the test scenario. The agents were found to be effective in very small quantities (<30 grams) for initial suppression of the fire, but permanent extinguishment was found to be a function of test conditions. The agents tended to accumulate on test surfaces and cause some corrosion as the result of repeated applications but were easily cleaned from affected surfaces.

This study was undertaken following the completion of a Small Business Innovtion Research (SBIR), Phase 2 contract involving the fire hazards if aerosoll cans. Tests were conducted on a newly designed aerosol can developed during the SBIR Pahse 2 contract as well as two types of currently produced cans. The purpose was to compare the hazards associated with typical aerosol cans versus the newly designed can when they are involved in an aircraft. The testing determinded that the new can created the least when involved in aircraft fire scenarios.
