Over-all length of vanes

Width of fuze body

The fuze body is cylindrical, with a central flange. Below this flange, the cylinder is threaded to screw into the bomb. Above the flange, the cylinder is also threaded to re-ceive a bullet-shaped vane cover in which the vanes are integrally cast. Beneath this cover, is the striker on a plate which screws into the upper part of the cylinder. Inside the base of the cylinder is a tube sliding into the cylinder but prevented from movement by the light creep spring resting against the top plate of the striker. In the bottom of the tube are twin detonator caps underneath the twin firing pins. Two steel balls are placed in holes in the cylinder, positioned is an annular slot in the tube containing the caps, and prevented from moving out-wards by the arming-vane cover. A hole throungh the striker and vane cover receives the safety pin.

When the flare is dropped, the safety pin is pulled, allowing the vanes to rotate. After the vanes have made a few rotations, the two steel balls can move out from under the vane cover, freeing the tube except for the creep spring. When the paracute opens, the case receives enough deceleration to cause the sliding tube to set forward, overcoming the spring and impacting the striker. The detonator caps are then fired.
