| Use: 30-mm projectiles for aircraft cannon. |
| Over-all length (with gaine): 1 3/16 inches. |
| Over-all length (without gaine): 1 inch. |
| Maximum diameter: 1 1/32 inches. |
| Threaded length: 5/16 inch R.H. |
| Number of threads: 4. |
|
Construction: The fuze consists of the main body which houses the
hammer, striker, ro-tor, and lower fuze body. The main body is made of
aluminum, the lower fuze body and gaine of brass; the remaining parts of
aluminum-magnesium mixture. The striker is carried in a rotor, which is
held in the unarmed position by two centrifugal detents. The lower fuze
body threads (R.H.) in the main body and is threaded (R.H.) internally to
take the gaine.
|
|
Operation: Centrifugal force causes the arming detents to move
out, freeing the rotor, which then turns the striker is in line with the
hammer. On impact, the hammer drives the striker into the primer, which
sets off the explosive train.
