Book excerpt: This report documents the development and testing of a standardized fire source for cargo compartment fire detection systems. Note that currently, these fire sources cannot be used in actual certification flight tests. The intent of this work was to define a fire source in terms of heat release rate, mass loss rate, and smoke and gas species production rates, and then devise a safe method to simulate whichever aspect of the fire signature that the particular detection system was designed to respond to in the certification tests. This could be done singly or in some combination with smoke generators, heat guns, and the controlled release of actual or surrogate gas species. This report discusses how this fire source is used in a computational fluid dynamics model to predict the transport of smoke, gases, and heat throughout a cargo compartment. The testing concluded that the fire source used in a simulated smoldering fire mode does not produce a fire signature that would be useful in developing multicriteria fire detectors with a better capability to resist false alarms. This report also documents the amount of smoke that would be detectable in various size cargo compartments and the resultant responses of currently in-use aircraft smoke detectors from the simulated smoldering and flaming fires.

Book excerpt: "There is a need to effectively develop and test an advanced fire detection system for aircraft cargo compartments that significantly reduces false alarms and improves alarm time response. Title 14 Code of Federal Regulations Part 25.858 requires that aircraft detection systems alarm within 1 minute of the start of a fire. Gas concentrations, temperature fluctuations, and particulate levels are three main parameters representative of a complete fire signature. Current aircraft detection systems depend solely on one parameter, particulate levels, for the detection of this wide fire signature. Improved fire detection capabilities can be achieved by combining multiple fire signatures or parameters in specific algorithms. An advanced fire detection system combining an ionization smoke detector, thermocouple, smokemeter, and a carbon monoxide (CO)/carbon dioxide (CO2) gas probe was installed in a Boeing 707 forward cargo compartment. A broad spectrum of fire and nuisance sources were tested to produce a matrix of extreme detector levels from all four sensors. This matrix provided alarm threshold criteria that aided in the development of a multisensor algorithm based on fire signatures such as CO and CO2 gas concentrations, temperature, ionization chamber voltage, and percent light transmission per foot. Multiple algorithms were created to determine the most effective multisensor algorithm that responded the fastest to fires while providing nuisance immunity."--Page ii
