GENERAL: |
|
The M150 fuze is an all-ways action fuze which screws into the tail for the M77 bomb. This fuze consists essentially of a zinc alloy fuze head, arming pin, striker, striker sleeve, and case, a steel striker pin, a M26 percussion primer and a starting mixture en-closed in a zinc cup. |
|
OPERATION: |
|
The retaining wire is removed when the fuzed bombs are assembled in the cluster. While the bombs are in the cluster, their proximity holds an arming band with springs against the head of the fuze, depressing the arming pin. When the bombs are released, the arming pin, together with the arming band, is forced out by the arming pin spring permitting the safety pin to enter the cavity in the striker. Impact forces the striker and sleeve together causing the striker pin to pierce the M26 percussion primer which in turn ignites the starter mixture, and subsequently the HC Smoke Mixture. |
