Safety and Arming Mechanism(SAM) for Mortar Fuze

This Paper contains introduction to safety and arming mechanism for Fuzes used in mortars. Presently this development process is carried out by using Reverse Engineering route. This invention relates to fuze having a mechanical delay device. The device also arms the ordnance section at the proper time through sensing that a predetermined set of conditions. The S&A device will provoke the explosives to initiate when the munitions senses that it has either hit or is in close proximity to the target. A safety and arming mechanism where in spinning as well as sliding member is held in an out-of-line position to align the explosive fuze train after the delay required. Actuator is activated when delay period is completed, arming the munition. An actuator releases the sliding member and moves the sliding member, which contains a stab detonator, to align and completing the fuze train towards a firing pin. Occurrence of arming and detonating occur instantly at same moment when the explosive train is completed and the stab detonator is impaled on the firing pin.
