Testing of the Engine Compartment Fire Extinguishing System in the F/EF-111 Aircraft

Abstract

Tests were conducted at the FAA Air Blast Test Facility during which Halon 1202 or Halon 1301 was discharged into the nacelle of an F/EF-111 test article through the aircraft's on-board agent distribution system. Various ground/flight conditions were simulated by providing controlled nacelle ventilating flows using by-pass air from a YTF-33 engine. Preliminary test indicated that some advantage resulted using the more volatile Halon 1301 agent. Tests also revealed that using either agent, the current on-board nacelle fire extinguishing system does not meet the recommended minimum requirements for an acceptable system in a major portion of the aircrafts operational flight envelope. And finally, the test results indicate that a revision to Mil-E-22285 should be considered. Keywords: Fire extinguishing agents; Fire protection.
