Controlled payload release mechanism for multiple stacks of pyrophoric foils to be contained in a single decoy device cartridge

Abstract

A decoy device including: a cartridge casing; and two or more pyrophoric assemblies disposed longitudinally in the casing for sequential ejection from the casing, the two or more pyrophoric assemblies including: a pyrophoric material; a piston positioned rearward in an ejection direction relative to the pyrophoric material, the piston being movable in the ejection direction upon application of ejection force to eject the pyrophoric material from the casing; one or more energetic materials positioned rearward in an ejection direction relative to the piston, the one or more energetic materials being initiated by electrical impulse to provide the ejection force to the piston; and an inert barrier layer positioned rearward in an ejection direction relative to the impulse cartridge.
