| Description: |
|---|
| The simulators have a one-piece aluminum case with an extracting rim, and resemble a large shotgun shell. The case contains a percussion primer mounted in the base, a black powder propelling charge, a delay fuse, and an inner case containing a flash charge. The primary difference is the higher reliability of the fuse in the M74A1. |
| Use: |
|---|
| To simulate artillery fire air bursts. |
| Functioning: |
|---|
| The simulators are fired from Pyrotechnic Pistol AN-M8. The firing pin of the pistol strikes the primer, igniting the propelling charge. The propelling charge expels the self-contained flash charge from the case, at the same time igniting the igniting charge. The igniting charge ignites the delay fuse, and the fuse in turn, ignites the flash charge producing a bright flash and a loud noise. The total delay from actuation of the firing pin to ignition of the flash charge is 2-3 seconds. Aimed at a 45 degree elevation, the height of burst is about 100 feet. |
