Description
Mechanical Time Fuzes M592 series are designed especially for use with flechette loaded 106mm Cartridge M581.
The fuze consists of an aluminum head, a lower cap containing the timing movement, and a steel body containing a detonator holder and plug assembly The rotatable lower cap is inscribed with range graduations from 200 to 3300 meters and an MA mm-k for muzzle action. The movement in the lower cap is a spring-driven clockwork mechanism combined with a muzzle-action feature activated by setback and centrifugal force, and uses the same firing pin as the time mechanism. The detonator holder located in the fuze body above the closing plug contains Detonator XM87. Two overlapping weights between Relay M11 at the upper end of the body and Detonator XM87 are moved by centrifugal force and constitute an interrupter-type safety provision.
The M592A1 is generally the same as the M563, M571, and M711 except for differences in acceleration and spin arming characteristics. The M592 differs from the M592A1 in that it has alpha weights instead of four setback weights.
