Fuze AR-MD
for Mortar Ammunition
AR-MD is a mechanical, nose, point-detonating fuze with super-quick action and distant arming. The fuze features highly sensitive impact mechanism and actions on solid ground, marshy ground and snow.
Fuze AR-MD completes High-Explosive, Incendiary and Smoke mortar bombs of the following caliber:
· 82 mm
· 120 mm
The fuze is safe in storage, handling and operation and ensures the safe and reliable function of the ammunition in all weather conditions.
The fuze is supplied with safety cap, which has to be removed before firing.
FUZE SAFETY
Before firing the Safety and Arm device prevents the detonator from positioning into the fire train. Even in case of unintentional ignition of the primer, no transfer of the firing pulse to the fire train can occur.
DISTANT ARMING
The fuze ensures distant arming of not less than 40 m from muzzle. At firing the set-back forces arm the fuze, fixing the elements of the fire train in one line.
FUZE ACTION
Upon impact the fuze provides SQ action. The fuze functions upon impact on solid ground, marshy ground and snow.
