UPGRADES OF PROJECTING CHARGE FOR APFSDS-T-TP AMMUNITION FIRED WITH 120 MM GUN OF LEOPARD 2 TANK

Abstract

APFSDS-T-TP ammunition of home production for 120 mm gun of LEOPARD 2 tank, being on the inventory of the Polish Armed Forces, has not passed the requirements of NO-13-A513 Defence Standard at certification tests against the random vibrations occurring at its tactical transportation inside the tank. Performed tests have indicated that the fulfilment of Standard requirements can be achieved by upgrading the igniting system what also makes the projecting charge design of APFSDS-T-TP ammunition change. The paper describes the research-development work on the upgrading of the igniting system for the cartridges used in 120 mm gun of LEOPARD 2 tank. The designs of the existing and upgraded igniting systems are presented both with the designing changes of projecting charges and ammunition ballistic and performance test results.
