Dynamic tests of new type fuses for shape charge projectiles of grenade launcher ammunition

Dynamic nondestructive testing methods for piezoelectric integrated fuses for arming one and two head shape charge projectiles of grenade launcher ammunition are described in the article. Presented results of study concern arming of fuses and resistance of their mechanical and electrical elements to overload during real shot (2600 g) and also during laboratory tests (1450 g). Tentatively calculated parameters of arming the fuse mechanisms: time mechanism, plunger of time mechanism, protective-driving plunger of primer holder, additional slide plunger (moving during second overload) were confirmed during applied tests.
