FIELD: physics.
SUBSTANCE: device consists of a hollow case, a pyrotechnic cartridge, a piston and a locking element. The piston of the pyrotechnic device has a tip on which a removable head is fitted through a thread. The locking element if held in the case through a thread and on a slide assembly in the piston. Permissible stress in the case and piston is greater than permissible stress in the locking element.
EFFECT: design of a reusable pyrotechnic device with controlled range of impact effects.
