ABSTRACT:
An enabling device 24 for a gas generator 42 of a forced dispersion munitions dispenser 10 includes a housing 58 in which and formed a bore 60, an outlet lead 88 and a detonator opening 68 in which is positioned an electrically initiated detonator 70. A piston 62 is located in the bore 60 and has a disabled position and an enabled position. A safety groove 64 is formed in the outer surface of the piston 62, and a safety passage 72, a safety aperture 74, 75 and a transfer lead 86 are formed in the piston 62. A gas generator 42 containing a quantity of pyrotechnic material 84 is mounted on the housing 58. The gas generator 42 is provided with a safety outlet 46, 47 and an inlet lead 44. When the piston 62 is in its disabled position, the safety groove 64 and the bore 60 in the housing 58 provide a path by which the products created by the detonator 70 being initiated are vented from the housing 58; and the safety passage 72, safety opening 76, 77 and safety outlet 46, 47 of the gas generator 42 and the bore 60 of the housing 58 provide a path by which gas produced by the gas generator 42 is vented from the housing 58. When the piston 62 is in its enabled position a firing train from the detonator 70 to the pyrotechnic material 84 is aligned. The firing train includes the transfer lead 86 of the piston 62, the output lead 88 of the housing 58, and the inlet lead 44 of the gas generator 42. Initiating the detonator 70 will, ignite the pyrotechnic material 84 of the gas generator 42. The piston 62 in its enabled position, closes the safety outlet 46, 47 of the gas generator 42.
