Description
This fuze is dangerous to handle if the aiming pin is out, because it has a heavy striker and a weak creep spring. This fuze should never be used for horizontal, glide, or dive bombing if there are any fuzes of the AN-M100 series available. It should never be used for skip or masthead bombing if there are any fuzes of the M112A1 or M115 series available.
The M106 had a longer coil of safety fuse, with a functioning time of 15 to 60 seconds. The M106A1 had a reduced functioning time of 8 to 11 seconds, for masthead bombing. M106, Long, was used in the Modified Mark series 2.000-lb GP bomb, having an overall length of 31.3 inches.
Functioning
The bomb is dropped and the arming wire is retained in the plane. The arming pin is ejected by the arming pin spring, arming the fuze. The striker which was held in place by the arming pin is now free and is prevented from resting upon the primer by a restraining spring.
Upon impact, the force of inertia causes the striker to move inward agaiqst the spring driving the firing pin into the primer. The flame from the primer ignites a black powder pellet which insures ignition of the safety fuse. The safety fuse burns from 45 to 60 seconds, at the end of which time, it ignites a second black powder pellet which insures functioning of the detonator of lead azide and tetryl. Upon detonating, the detonator starts a shattering wave which functions the bomb.
