| Description: |
|---|
| The bomb body consists of a thin sheet-steel cylinder with a tail plate welded at one end and a nose at the other. The nose is recessed to accommodate a cast-iron weight, which is secured in position with bolts. Throe perforated baffles are welded internally to the bomb case to reduce surging of the filling while the bomb is suspended aboard the aircraft. An internally threaded adapter in the center of the tail plate serves as a charging bole and also for the fitting of the exploder container. A cowl welded to the tail plate has six equi-spaced springs riveted inside it. These spring form an attachment for the six' fasteners which secure the tail unit to the bomb. These fasteners consist of a stud and a leaf spring. The studs have an external screw-driver slot and an internal cam slot. The cam slot engages the spring: attached to the cowl. |
