1. A fire suppression system for a jet engine, comprising:
a jet engine having a source of fuel, a jet engine air intake, a jet engine outlet through which a combusted air and fuel mixture is exhausted at a high speed along a first flow path to apply thrust;
a streamlined enclosure forming a volume around the jet engine, the volume having an air intake and an air outlet so that air flows through the volume between the streamlined enclosure air intake and the streamlined enclosure air outlet at a speed that is lower than the high speed first flow path, wherein the streamlined enclosure defines
one or more flame holding regions capable of sustaining a spatially stable flame in the presence of an oxidizer and fuel, and
one or more predetermined natural flows of at least one of an oxidizer and a fuel within the volume that respectively pass through one or more predetermined said flame holding regions;
a reactive agent; and
an injection point for the reactive agent disposed in the streamlined enclosure, the injection point being directed to one or more predetermined natural flows that flow through a reaction zone so that releasing the reactive agent at the injection point into the at least one of the one or more predetermined natural flows causes the at least one of the one or more predetermined natural flows to transport the reactive agent to the reaction zone and wherein the reactive agent reacts to produce a catalytic fire suppressing agent, and so that a minimum amount of the reactive agent sufficient to suppress a fire at the at least one of the one or more predetermined flame holding regions when injected into the at least one of the one or more predetermined natural flows is less than a minimum amount of the reactive agent sufficient to suppress the fire by flooding the volume with the catalytic fire suppressing agent.
