- Abstract
- Test fires were conducted in the fire zone of a jet power plant in order to determine the minimum amounts of fire-extinguishing agents required for extinguishment under different conditions of air flow through the zone. The tests were conducted with four extinguishing agents which were discharged through conventional and experimental systems: first, with the zone in its original condition, and later, with a lining in the lower portion of the fire zone to provide a smoother flow of air. Results indicate that the rate of air flow influenced the amount of extinguishing agent required for extinguishment of the test fires. With the lining installed, the quantity of fire-extinguishing agent required was approximately a linear function of the rate of air flow. Without the lining and at the lower rates of air flow, burning fuel fell to the bottom of the nacelle and collected between the structural members or ribs. This resulted in increased extinguishing agent requirements. The results also indicate the effectiveness of each of the four extinguishing agents tested and provide a comparison between the two systems.
