- Abstract
- Fire tests and extinguishant concentration tests were conducted using a simulated portion of the F-16 aircraft engine compartment in the Aircraft Engine Nacelle (AEN) fire test simulator at WPAFB. Combat damage simulation included outer compartment wall penetration allowing either inflow or outflow of ventilation airflow through an external would and can perforation or engine bleed air line damage. "Standard" fire and agent concentration test techniques were developed. Existing specifications were found to be adequate in terms of quantity of extinguishing agent. Results also indicated that more rapid agent release resulted in more effective use of the agent. Halon 1301 performed significantly better than Halon 1202, contrary to what the available literature indicated. Fires with combat damage inflow simulation added were the most difficult to extinguish because hot surface ignition sources were created soon after the test fire was ignited. For these, the quantity of agent specified would have been adequate only if the agent reached the fire within a few seconds after ignition.
