Body Construction: The body consists of a cylindrical steel shell with a hollow, coni-cal nose piece welded to one end, parallel sides, and a closing plate bolted to an angle ring which is welded in position a short distance within the other end. A radial strengthe-ning band is welded internally at the center of gravity, and its ends are welded to a steel block. Holes tapped through the shell and steel block receive the suspension-lug screws. Side pockets for supplementary fuzing are present near the base end, but are not used. The shell is strengthened longitudinally by two channel beams welded to each end of a central steel block and to the shell interior. |
|
Tail Construction: The Tail No. 32 Mk I assembly consists of a cylinder of light-gauge metal with a metal tray secured in its forward end and a strengthening ring in its open rear end. The tray has a series of equispaced bayonnet dogs for attaching to the body bayonnet joints welded to it. The cylinder has a number of openings to give it stability. |
|
The parachute attachment has a parachute 5 ft. 6 in. in diameter, attached it to the body. The parachute is retained by waterproofed fabric and a retaining pin. The retaining pin is attached to a static cord stitched on the outside of the last protective panel, and connected to the bomb carrier or aircraft. On release the cord pulls the retaining pin and chute free, and breaks off from the plane when the chute is extended. |
|
Suspension: The bomb is suspended by a single suspension lug bolted to the body and an internal steel block at the center of gravity. The screw holes are closed by tran-sit screws until the bomb is to be used, at which the lug is attached. |
