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.

Heat transfer initiator

A heat transfer delay for providing a delay time in propellant, pyrotechnic, and explosive devices, and a method of delaying production of a non-detonating thermal output with the heat transfer delay. A representative delay is in the form of a housing having a first heat source cavity, a second heat source cavity, and a heat transfer cavity connecting the first and second heat source cavities. A pyrotechnic heat source is placed in thermal contact with the first heat source cavity, and a non-detonating autoignition material is placed in thermal contact with the second heat source cavity. Upon ignition and combustion or reaction, the pyrotechnic heat source generates an amount of heat sufficient to heat the first heat source cavity to a temperature sufficiently high to cause a transfer of a sufficient amount of heat through the heat transfer cavity to the second heat source cavity to heat it to a temperature sufficiently high to ignite the non-detonating autoignition material, and produce a non-detonating thermal output therefrom, where the heat transfer bridge conducts heat at a rate such that a delay time of at least about 0.5 second elapses between ignition of the heat source and ignition of the non-detonating autoignition material.
