Abstract: A decoy flare for infrared (IR) seeking missiles comprises a tubular outer shell with a first rupturing disc sealing a rear end of the outer shell and a cover member with a second rupturing disc sealing a front end of the outer shell. These form a sealed container for a pyrophoric liquid. A nozzle cap is attached to the cover member with a nozzle being located in front of the second rupturing disc. A piston in the container adjacent the first rupturing disc separates the pyrophoric liquid from the disc. A holder for a gas generator, a disc of energetic material, is connected in sealed relationship to the container to position the gas generator adjacent the first rupturing disc and form a gas generating chamber between the holder and that disc. That holder contains an ignition mechanism for the gas generator and a seal to prevent gases from escaping via the ignition mechanism after it is activated.
