An energetic material having thin, alternating layers of metal oxide and reducing metal is provided. The energetic material may be provided in the form of a sheet, foil, cylinder, or other convenient structure. A method of making the energetic material resists the formation of oxide on the surface of the reducing metal, allowing the use of multiple thin layers of metal oxide and reducing metal for maximum contact between the reactants, without significant lost volume due to oxide formation. An ignition system for the energetic material includes multiple ignition points, as well as a means for controlling the timing and sequence of activation of the individual ignition points. A gas producing layer is also provided to increase pressure.

A diversionary device capable of providing multiple discharges according to a prescribed time schedule. The device preferably assumes the same general form as a prior art stun grenade, including a safety pin that is pulled to arm the device and a spring-biased lever that is released when the device is deployed.

A fuse mechanism for e.g. a pyrotechnic grenade in which a spring loaded striker lever (31) is blocked via a cammed surface (22) of a safety lever (21) comprising a handle. (25). Release of the handle (25) enables deployment of the fuse assembly. Spring-loaded striker lever (31) is urged upwards by the force of torsion spring (38). Contact between the free end (34) of the striker lever (31) exerts a rotational force on cammed portion (22). The safety lever (21) rotates away from the body of the munition (20). Rapid upward movement of the striker lever (31) is prevented at this stage by contact of the free end (34) with the cammed portion (22). Further rotation of the safety lever (21) occurs until point where the cammed portion (22) is no longer in contact with the striker lever. Ultimately, once the safety lever (21) has rotated beyond a certain extent, the free end of the striker lever (31) is no longer in contact with the cammed portion (22), and the striker lever is urged rapidly away from the body of the munition (20).

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 timesspecifically 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).
