Abstract
A infrared flare is used as a military decoy for infrared heat seeking missiles. The flare burns a pyrophoric fuel to provide a good simulation of an aircraft spectral signature. To minimize blow-out under extreme wind and high altitude conditions, the flare has an oxygen injector arranged concentrically around the fuel ejector and a shroud sheltering an ignition space just downstream of the fuel ejector. The injected oxygen reacts with a small amount of the fuel to produce a pilot flame in the shroud.
