The present invention relates to flares and other solid propellant devices, rockets or the like, equipped with an igniter or igniter system which is based in whole in part on an extruded igniter stick.
[ What we claim is:] [1.] A flare comprising a case, propellant contained within said case, and an igniter system comprising an extruded dry igniter element for igniting said propellant of said flare, said extruded dry igniter element deflagrating upon ignition and being formed from an extrudable ig
[ What we claim is:] [1.] A flare comprising a case, propellant contained within said case, and an igniter system comprising an extruded dry igniter element for igniting said propellant of said flare, said extruded dry igniter element deflagrating upon ignition and being formed from an extrudable igniter composition comprising, as ingredients prior to drying to form said dry igniter element, at least one water-soluble binder dissolved into an aqueous solution, at least one oxidizing agent, at least one fuel, and, optionally, fibers,wherein said water-soluble binder comprises at least one member selected from the group consisting of a water-soluble polymeric binder, a water-soluble gum present in an amount of from about 2% by weight to about 10% by weight based on the total amount of dry ingredient in said extrudable igniter composition, and water-soluble gelatin, andwherein formation of said extruded dry igniter element comprises drying the extrudable igniter composition of water.
