Traditional cargo fire detection systems rely on fixed thresholds, such as a specific temperature, to trigger alarms. However, these static approaches are prone to false positives and may miss slow-developing fires. This patented system introduces a novel method that evaluates sensor data dynamically, based on both spatial location and temporal evolution. Temperature sensors distributed throughout the cargo compartment generate continuous data streams which are analyzed over defined time windows. The system compares sensor values across locations and over time, identifying anomalies that indicate real fire events rather than harmless fluctuations. Configurable parameters allow operators to adapt detection sensitivity to different operational conditions, cargo types, and environmental variables. This method supports early detection of fires in Class C cargo compartments, including those inaccessible during flight. It is designed to integrate with aircraft health monitoring and fire suppression systems, and it can be deployed in both new aircraft designs and as a retrofit to existing platforms equipped with sensor arrays.

Traditional fire testing methods often require large samples, open flames, or complicated setups to study combustion. This technology introduces a compact, precise method using a Microscale Fire Calorimeter (MFC) that mimics realistic fire conditions with unprecedented control. When a solid material is thermally decomposed (pyrolyzed), it emits gaseous byproducts. These gases are then premixed with oxygen and combusted in the MFC’s reaction zone at high temperatures, without a visible flame. The MFC system precisely regulates oxygen availability, simulating different fire stages such as over-ventilated (oxygen-rich) and under-ventilated (oxygen-poor) conditions. This allows researchers to analyze how combustion chemistry changes as fires become more intense or oxygen-deprived. The system captures and quantifies the resulting gases and soot, enabling evaluation of environmental pollutants and toxic species produced during each combustion phase. This approach supports safer, smaller-scale laboratory testing while providing valuable data for applications such as material development, regulatory compliance, and forensic analysis. It bridges the gap between benchtop research and real-world fire scenarios.
