A damper system for a pyrotechnic time delay may comprise: a firing pin; a moveable housing defining a chamber therein; a fixed piston comprising a piston head disposed in the chamber, a first rod extending from the piston head axially outward of the moveable housing, and a second rod configured to fixedly couple to a housing; a first spring extending axially from the moveable housing to the firing pin; and a second spring extending axially from the moveable housing to the firing pin.

In order to improve safety, particularly during transportation and/or storage, a system (10) is proposed which at least comprises a housing (13) an explosive (3) held therein which is initiated by a blasting cap (1), wherein a sleeve insert (2, 2′) in the housing (13) makes it possible for the blasting cap (1) to be removed from the explosive (3), in that the blasting cap (1) in the sleeve insert (2, 2′) is height-adjustable, so that the position of the blasting cap (1) relative to the explosive (3) can be changed. The system (10) may include a fuse head (11) which at least comprises a primer cap and possibly a delay line (14). The blasting cap (1) may be an integral part of the fuse head (11) and insulated therewith on the base.

The invention relates to a detonator system for hand grenades, having an ignition element (1) which after initiation triggers a delay and safety device, which, with a time delay after the initiation, fires a detonator (7), which then ignites an ignition booster (8), wherein the delay and safety device includes a dual safety device of two independent parts. So that the hand grenade detonator system according to the invention includes a purely pyrotechnic detonator system instead of a pyrotechnic-mechanical system, it is suggested that the delay and safety device consists of two pyrotechnic ignition delay devices with different delay times—specifically a safety element (3) and a delay element (4)—wherein the delay time of the safety element (3) is shorter than the delay time of the delay element (4), and the safety element (3) includes a timing composition which, once it has burned through, ignites a gas charge (9), the gas of which opens blocking elements (5), and the delay element (4) includes a firing charge, and the firing charge is only in operative connection with the detonator (7) after the opening of the blocking elements (5).

Examples of safety devices for use with a munition are provided, the munition including a munition explosive and a safe and arm (S&A) device for activation of the munition explosive. In some examples the safety device includes a switch member and an actuation mechanism. The switch member is configured for being disposed between the munition explosive and the S&A device, the switch member being movable between at least two switch positions. In a first switch position (an arming prevention position (APP)), arming communication between the munition explosive and the S&A device is prevented. In a second switch position (an arming enabling position (AEP)), arming communication between the munition explosive and the S&A device is allowed. The actuation mechanism is configured for selectively moving the switch member at least from the APP to the AEP to thereby enable the S&A device, when armed, to detonate the munition explosive via the switch member.

This invention describes embodiments of door breaching grenades (100,100a,100b,100c,100d). Each grenade comprises a projectile (101,101a,101b,101c,101d) coupled to a propulsion cartridge (105); each projectile comprises a shell (110), a body member (140) and an ogive (180). A safe-and-arm mechanism (150) is located in the body member. A seat member (160) and a plunger (166) are assembled on a forward face of the body member so that a leading end of the plunger is in contact with an inside tip surface of the ogive, or a hollow guide member (184) is integrally formed with an inside tip surface of the ogive. In the armed state, upon impacting on a door/barricade (5), the plunger or hollow guide/sleeve impinges on a detonator pin (164), which then sets off a chain of explosive charges (152, 120, 122) whilst the projectile is still outside the door/barricade. The grenade is made substantially of polymer parts.
