Abstract:

This study was conducted to investigate the response of various fire detectors and automatic sprinklers in high bay aircraft hangars. Laboratory and full-scale experiments as well as computer modeling were conducted to better understand the movement of heat and products of combustion in high bay spaces. Temperature distribution across the ceiling was measured along with the response of various types of fire protection devices as a function of fire size, fuel type, and ventilation conditions. Key findings are presented relating to detector spacing, threshold fire sizes, sprinkler type and temperature ratings, burn rates, heat release rates, and the effect of draft curtains.
