Abstract

An aerial flare having a safe-and-arm ignition system in which a radially vable valve element or slider is retained in a safe position obstructing ignition ports by engagement of the slider with interior walls of the flare casing. To deploy the flare, an expulsion charge is electrically detonated, ruptures a frangible barrier, ignites primer in the igniter, and expels igniter-illuminant assembly from the forward end of the casing. When the igniter clears the casing, the slider is powered radially outwardly under the force of a biasing spring to uncover the ignition ports so that the parts are in an arm position. The flaming primer then ignites the illuminant through the open ignition ports.
