Survey of Fire Detection Technologies and System Evaluation/Certification211 Methodologies and Their Suitability for Aircraft Cargo Compartments

摘要

As part of the National Aeronautics and Space Administration (NASA) initiated211u001eprogram on global civil aviation, NIST is assisting Federal Aviation 211u001eAdministration in its research to improve fire detection in aircraft cargo 211u001ecompartments. Aircraft cargo compartment detection certification methods have 211u001ebeen reviewed. The Fire Emulator-Detector Evaluator (FE/DE) has been designed to 211u001eevaluate fire detection technologies such as new sensors, multi-element 211u001edetectors, and detectors that employ complex algorithms. The FE/DE is a flow 211u001etunnel that can reproduce velocity, temperature, smoke, and Combustion gas levels 211u001eto which a detector might be exposed during a fire. A scientific literature 211u001esurvey and patent search have been conducted relating to existing and emerging 211u001efire detection technologies, and the potential use of new fire detection 211u001estrategies in cargo compartment areas has been assessed. In the near term, 211u001eimproved detector signal processing and multi-sensor detectors based on 211u001ecombinations of smoke measurements, combustion gases and temperature are 211u001eenvisioned as significantly impacting detector system performance.
