The invention relates to a hand grenade fuse, comprising an igniting cap (16), a delay composition (13) in a delay composition receptacle (12) to be ignited by the igniting cap (16), a detonator (10) in a pivotable detonator retainer (11) to be ignited by the delay composition (13), and a booster charge (9), to be ignited by the detonator (10), for igniting a hand grenade explosive device.
摘要:
A charge for cutting a casing (10) comprising a plurality of propellant sections (20) arranged in a stack and interspaced with a flame retardant material (38). A modifying agent is provided with the propellant. An ignition mechanism (58) causes the propellant to deflagrate rather than explode, producing a high pressure stream of combustion products.
摘要:
A energy transfer device (10) is provided that is capable of transferring the energy output from one pyrotechnic device (52) to another device (78) for initiating firing thereof. Device (10) comprises a device housing (12) in which a deformable device insert (14) is received. Device insert (14) comprises a central passageway (34) for transmitting the output from a pyrotechnic device (52), including energy, gasses, and/or solids, to another pyrotechnic device (78). The passageway (34) conducts the pyrotechnic device output to a precise location on the second pyrotechnic device (78) where firing is most effectively initiated. The energy transfer device (10) may be employed as a part of a tool (44) used in well completion operations.
摘要:
The invention relates to an igniter system for hand grenades with an igniting element (1), which after initiation triggers a delay and safety device, which with a time delay after the initiation fires a detonator (7), which subsequently ignites an ignition booster (8), wherein the delay and safety device comprises a dual safety device of two independent parts. In order that the igniter system according to the invention for hand grenades comprises a purely pyrotechnical igniter system instead of a pyrotechnical-mechanical system, it is proposed that the delay and safety device consists of two pyrotechnic ignition delays with different delay times, that is to say 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) comprises a timer which carries out ignition after the burning off of a gas charge (9), the gas of which opens blocking elements (5), and the delay element (4) comprises a firing charge, and the firing charge is only in operative connection with the detonator (7) after the opening of the blocking elements (5).
摘要:
Die Erfindung geht aus von einem Zünder (2) für ein Geschoss mit einer Zündanordnung (54) zum Zünden einer Hauptladung des Geschosses und einem Verzögerungsdetonator (10) zum Zünden der Zündanordnung (52) nach einer durch eine Abbrandstrecke (66) einer Verzögerungsladung (30) festgelegten Verzögerungszeit, wobei der Verzögerungsdetonator (10) ein Gehäuse (26) mit einer Zündhälfte (60), in der er gezündet wird, und einer Detonatorhälfte (62), die eine Detonatorladung (34) zum Zünden der Zündanordnung (54) beinhaltet, aufweist. Um ein Blindgehen des Geschosses durch eine zu frühe Detonation des Verzögerungsdetonators (10) zu vermeiden, wird vorgeschlagen, dass das Gehäuse (26) in der Zündhälfte (60) eine Entlastungsöffnung (40) mit einem im zündenden Zustand des Verzögerungsdetonators (10) frei durchgängigen Öffnungsquerschnitt aufweist.
摘要:
An air-burst detonation ballistic (10) for grenade launchers. The ballistic (10) can be fired from an unmodified grenade launcher, such as M-79, M-203, Granatpistole, and Mk 19 grenade launchers. The less-than-lethal ballistic (10) comprises a concussion element (13), a phosphorescent (13), and a chemical irritant (11). The nose of the ballistic comprise an energy-absorbing cavity (20) and a switch (21) preventing detonation of the ballistic (10) on impact.
