for Tank Ammunition
V-429E is a mechanical, nose, point-detonating fuze with selectable super-quick or delayed action.
The fuze is designed for ammunition for smoothbore tank guns. It completes High-Explosive, Incendiary and Smoke rounds for the following guns:
· 100 mm anti-tank guns T-12, MT-12 and M-87
· 115 mm tank gun U-5T mounted on T-62 MBT
· 125 mm tank gun 2A46 and its modifications mounted on T-64, T-72, T-80, and T-90 MBTs
V-429E fuze features locking at firing from worn-out or strongly contaminated barrel.
The fuze is safe in storage, handling and operation and ensures the reliable and safe function of the ammunition in all weather conditions.
The fuze has two operation modes, which are selectable, by built-in setter and wrench:
position “O” for SQ action
position “З” for delayed action
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.
At firing the set-back forces arm the fuze, fixing the elements of the fire train in one line. The fuze is armed within 5 to 20 m from muzzle.
Upon impact the fuze provides SQ or delayed action of 0.027 to 0.063 s.
The fuze functions under the impact and inertia forces. The inertia device ensures ignition not only upon impact on solid ground, but also on snow or marshy ground.
