A decoy flare for infrared (IR) seeking missiles comprises a tubular shell with a cover member hermetically sealed to an outer front edge of the tubular shell to form a container for a pyrophoric liquid. The cover member has a central rupturing disc that ruptures at a predetermined pressure, a nozzle cap with a nozzle opening being attached to the cover member adjacent an exterior surface of that rupturing disc. Pressure applied by a mechanism to the pyrophoric liquid can rupture the rupturing disc and eject the pyrophoric liquid through the nozzle. A pre-heating chamber formed by an enclosure surrounds the nozzle opening in order to provide for more reliable ignition of the pyrophoric liquid at high altitudes and low flow rates, that enclosure having an outer surface containing a number of perforations through which air can enter the pre-heating chamber and through which pyrophoric liquid can be ejected from the chamber into the atmosphere.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A decoy flare for infrared (IR) seeking missiles comprising a tubular outer shell with a cover member hermetically sealed to an outer front edge of the tubular shell which forms a container for a pyrophoric liquid located in the tubular shell, the cover member having a central rupturing disc that ruptures at a predetermined pressure with a nozzle cap having a nozzle opening being attached to the cover member adjacent an exterior surface of the rupturing disc, the nozzle opening being located in front of that exterior surface, the flare having a pressure generating mechanism for applying pressure to the pyrophoric liquid to rupture the rupturing disc and eject the pyrophoric liquid through the nozzle opening wherein that nozzle opening opens into a pre-heating chamber located in front of the cover member, the pre-heating chamber being formed by an enclosure surrounding the nozzle opening which enclosure has an outer surface spaced from the nozzle opening, the outer surface having a number of perforations through which air can enter the pre-heating chamber and through which pyrophoric liquid can be ejected from the chamber into the atmosphere.
