Abstract:

A series of fire experiments were conducted in two aircraft hangars with ceiling heights of 15 m (50 ft) and 22 m (73 ft). The purpose of the experiments was to analyze the activation characteristics of smoke and heat detectors in response to JP-5 and JP-8 pool fires. The 15 m (50 ft) hangar was located in Hawaii, where ambient temperatures were approximately 30 deg C (86 deg F). The 15 m (50 ft) experiments used fire sizes that ranged from 100 kW (95 Btu/s) to 7.7 MW (7300 Btu/s). Experiments were conducted with and without draft curtains in the 15 m (5O ft) hangar. The 22 m (73 ft) hangar was located in Iceland, where ambient temperatures were approximately 12 deg C (54 deg F). The 22 m (73 ft) experiments used fire sizes that ranged from 100 kW (95 Btu/s) to 33 MW (31000 Btu/s). Draft curtains were present for all the 22 m (13 ft) experiments. Open- and closed-door fire experiments were conducted in both hangars.
