The delay element includes Primer M54, a black powder delay charge and Relay M7. Point Detonating Fuze M572 is intended for use only with 175mm, HE projectiles at all charges, and Is designed to withstand structurally the acceleration forces involved. %��������� 4 0 obj Related Products. An aluminum booster cup containing a 340-grain tetryl booster pellet is threaded to the booster body. (This fuze is equivalent to M739A1 Fuze.) On firing, the locking mechanisms are released and the rotor becomes aligned with the booster lead charge and the fuze flash tube when set for PD action or the fuze delay plunger relay charge when set for "delay" action. The fuze is safe in storage, handling and operation and ensures the safe and reliable function of the ammunition in all weather conditions. The M51A5 fuze consists of Fuze M48A3 assembled with the M21A4 booster. ��8E>{:�Z:��ܵYj�d����G��T/`��@tf�vOLd2�&3X� R(��:+������*�-�j�x�1�HК�G�w�>BU?��`M��>d��2

US point detonating fuze of 1915 combining adjustable timer up to 21 seconds, using a gunpowder train, and impact mode. 80 "Time & Percussion" fuze licensed from Krupp was Britain's main WWI shrapnel fuze. The ogive is a thin-walled steel stamping utilized to provide an aerodynamic shape to the fuze. stream The setback forces retract the booster lock pin allowing centrifugal force to extract the rotor lock pin and permitting the rotor to rotate into an armed position aligning the rotor M17 detonator with the detonation train of the fuze.
