Fuzes |
Nose Fuze No. 874 Mk I (Service) |
Data |
Bombs used in | 250-lb. T.I. No. 8 |
Action | Instantaneous on impact |
Armed condition | When the vanes and vane cap are off |
Description: The pistol consists of a vane cap, body, striker guide, and detonator holder. It is similar in principle to the Pistol No. 45. The main constructional differences between the fuze and pistol are that the fuze includes a detonator, and has a brass adapter to permit it to be threaded into the nose of a T.I. bomb. |
Operation: The safety pin is removed when the bomb is loaded aboard the plane. Upon release, the arming vanes rotate up and off the fuze body, thus arming the fuze by exposing the diaphragm and retaining disc. On impact, the diaphragm is reversed by the compressed air beneath the fuze, and the striker is driven into the detonator. |
