| Description: |
|---|
| The fuze has a one-piece aluminum body containing a striker in the nose to drive a firing pin. The firing pin is held by two spring-loaded detent pins. A disk-shaped rotor containing the detonator is axially in line with the firing pin. The rotor housing restricts rotor movement to the transverse axis of the fuze. The detonator is held out of line until arming by two springloaded pins which lock the rotor m position. A base plug containing the booster lead charge and booster charge is threaded into the base of the fuze. |
| Use: |
|---|
| Point Detonating Fuze MK27 is of the superquick type designed to function on light impact. The fuze is used with 40mm gun HE ammunition. |
| Functioning: |
|---|
| Upon firing, as the speed of rotation becomes sufficient, centrifugal force withdraws the detent pins from the firing pin and from the rotor against the resistance of the pin springs. Upon release from the detent pins, the rotor revolves to align the detonator with the firing pin and with the booster lead charge. Upon impact, the striker drives the firing pin into the detonator. Detonator action is transmitted through the booster lead charge and booster charge to explode the projectile. |
