STUDY OF FLAME PROPAGATION THROUGH AIRCRAFT VENT SYSTEMS.

Abstract

The purpose of the study was to investigate flame propagation in the vent systems of turbine aircraft under simulated flight and ground operating conditions. The function of a venting system is to keep the pressure differential across the walls of aircraft fuel tanks to a minimum during refueling and during the most rapid altitude changes that the aircraft can experience. The vent systems are often designed to prevent spillage of liquid fuel from the aircraft by the utilization of dead-ended sections of vent ductwork and/or fuel slosh collection tanks. The hazard associated with aircraft fuel vent systems is attributed to the fact that the fuel vapors handled by the vent systems are flammable in air under certain conditions. When these conditions exist and an ignition source of sufficient energy is present, the fuel vapor-air mixture will ignite. The combustion process following ignition in a mock-up aircraft vent system has been investigated. (Author)
