Abstract
Provided is an ignition safety system arming confirmation device and an arming monitoring system including the same, and more particularly, an electro-mechanical ignition safety system arming confirmation device for ignition of a rocket motor and an arming monitoring system including the same, which provides greater accuracy in detecting an arming status and a safe status by using a permanent magnet and a Hall sensor.
Claims19
An ignition safety system arming confirmation device for a rocket motor, the device comprising:
- a torque motor installed inside a housing of an ignition safety system and transmitting rotation power;
- a detonator holder capable of rotating by a predetermined angle by having a rotation shaft of the torque motor that is inserted thereinto and fixed thereto, and comprising a pair of wings formed to be symmetrical with each other around the rotation shaft;
- at least one permanent magnet disposed on an outer wall of the detonator holder and between the pair of wing parts;
- and
- a plurality of Hall sensors formed by extending to one side of the torque motor, disposed between the pair of wing parts of the detonator holder, and detecting a magnetic flux from the permanent magnet as the detonator holder rotates.
