Abstract: A non-detonating heat transfer initiator. A representative heat transfer initiator is in the form of a heat transfer control medium, having a heat input portion and a heat output portion, and a non-detonating autoignition material, having an autoignition temperature, in thermal contact with the heat output portion. When heat is applied to the heat input portion, a transfer of heat through the heat transfer control medium to the heat output portion results, heating the heat output portion, such that, upon application of a sufficient amount of heat to the heat input portion, the heat output portion is heated to the autoignition temperature of the non-detonating autoignition material, igniting the non-detonating autoignition material ignites, thus producing a non-detonating thermal output.
