Proposals have been made to carry liquid nitrogen (LN2) aboard commercial aircraft for the purpose of powerplant fire extinguishment. Testing was conducted to determine the feasibility of using LN2 as an aircraft powerplant fire-extinguishing agent and also to determine the characteristics of LN2 when used as an extinguishment. The tests were conducted in a fire test facility using a full-scale aircraft turbojet engine and nacelle for subsonic low-altitude flight condition simulation and also in a mockup engine/nacelle facility where nacelle volume and airflow could be varied. All fire tests were conducted using JP-4 jet fuel which was spray released and spark ignited. The report also describes the effects of an inadvertent discharge on engine components, the effects of a damaged cowling, and the cooling of potential reignition sources.
