M06/17

These fuze are combustion types with two time rings. The upper ring is fixed, and the lower setting ring is graduated to 59 and numbered to 58. The cap is aluminum. The rings and body are aluminum alloy, but the perophery of platform bearing setting index is sometimes brass. The A.D.E. M06 has a recess in the rear portion which houses the se-cond firing pin, creep spring, split arming ring, and detonator holder, which causes the fuze to detonate on impact, whereas the M06/17 will not detonate on impact, but de-pends on a time element. In a recess in the forward position of both type fuzes, are lo-cated the detonator holder, stirrup spring, locating spring, and firing pin. The time rings are of normal design, each heaving tightly closed vents containing a perforated powder pellet at the commencement of the fuze powder train. The tension of the setting ring is adjusted at assembly by a screwed cap, secured by a setscrew.

M06/17: On acceleration, the detonator holder overcomes the stirrup spring and sets back, carrying the detonator to the firing pin. The flash produced is transmitted to the perforated pellet in the upper time ring, starting the fuze powder burning. The fuze burns around to the perforated pellet in the lower time ring and ignites the fuze powder. The lower ring burns and ignites the pellet in the fuze base which in turn flashes to the main charge.

A.D.E. M06: Operation for the time part of the fuze is exactly the same as the M06/17. Operation for the percussion parts differs. On setback, the split arming ring sets back and locks to position of the detonator holder. The creep spring keeps the firing pin and detonator apart. On impact, the detonator overcomes the creep spring and hits the firing pin.
