Abstract: Provided is an initiator for a rocket motor. The initiator for a rocket motor includes: a sleeve assembly configured to form a hollow portion; and an ignition assembly including a plug portion mounted on the sleeve assembly to close one side of the hollow portion and configured to deliver an electrical signal and a foil ignition portion coupled to the inside of the plug portion to be adjacent to the hollow portion. The sleeve assembly includes: a first gunpowder accommodated in the hollow portion to be adjacent to the foil ignition portion and detonated by the foil ignition portion; and a second gunpowder accommodated inside the hollow portion to contact the first gunpowder and deflagrated or combusted by the detonation of the first gunpowder.

Abstract: The present invention relates to an igniter assembly, including a blast tube provided with a supporting part formed in a cylindrical shape, and an aft-closure part having front and rear sides through which igniter combustion gas is emitted, an igniter disposed adjacent to the rear side of the aft-closure part and storing ignition pellet therein, and a blast tube stopper formed in a shape surrounding the supporting part, accommodating the igniter, and coupled to the rear side of the aft-closure part, wherein the aft-closure part includes a plurality of holes through which igniter combustion gas is emitted.

Abstract: Provided is an ignition safety device for a rocket motor. The device includes an ignition circuit part including a main body and a control unit configured to generate an initiation signal on the basis of a specific signal, and an initiation part mounted at one end of the ignition circuit part and including at least one high voltage initiator electrically connected to the ignition circuit part. The initiation part includes a housing having at least one reception space for receiving the at least one high voltage initiator, and the housing and the main body are coupled by welding.

Abstract: An arm-fire device comprises a capacitor charged by an arming signal; an acceleration switch for generating an operation signal if an acceleration more than a predetermined acceleration is sensed; a controller electrically connected with the capacitor and the acceleration switch, controlling generation of a firing signal; and a through bulkhead initiator provided with an ignition portion installed at a space separated by a bulkhead and configured to be electrically connected with the controller to ignite the ignition portion if the firing signal is transferred thereto, wherein the controller discharges the capacitor to generate the firing signal when the operation signal and a launching signal, which is applied from outside, are all sensed in a state that the capacitor is charged. The arm-fire device is applied to a multi-stage rocket, etc., whereby the probability of accidental ignition may be lowered.
