ENERGY PYROTECHNIC IGNITER Russian patent published in 2024 - IPC F42B3/12 F42C19/08 

FIELD: devices for ignition of energy materials.

SUBSTANCE: invention relates to an energy pyrotechnic igniter. Energy pyrotechnic igniter consists of a board with a dielectric film with low thermal conductivity and with formed on it contact pads and arranged between contact pads conducting multilayer energy film with effect of self-propagating high-temperature synthesis (SHS) with resistive bridge, made of the same conductive multilayer energy film, and coated with a thermite multilayer energy film from NiO/Al, or CuO/Al, or MoO₃/Al, or CuO/Ti, or NiO/Ti. A dielectric film with thickness of 2–4 mcm is additionally placed on the board between the contact pads and the conductive multilayer energy film with formed areas in locations of contact pads and with configuration of contact pads. On the dielectric film there is a region formed in it in the form of a resistive bridge, which further serves as a mask through which the configuration of the resistive bridge will be formed.

EFFECT: creation of design of energy pyrotechnic igniter with low electric power of ignition, with low current of initiation by increasing the resistance of the resistive bridge and ensuring the formation of a given configuration of the resistive bridge without etching the material of the multilayer energy film without using high temperatures when forming photoresist films.
