British Bomb, 500 lb Smoke, Mk 2

 

1394-090

Description

The bomb consists of a cylindrical bomb body made of thin sheet steel, with a nose plate welded to one end of the body. Three catch brackets, spaced 120' apart, are welded to the nose plate, and a nose fairing is secured to the catch brackets by spring clips. Immediately beneath the nose plate is located a loading plate. An exploder pocket is welded to the nose plate and contains an ejection charge. A nose plug is screwed into the exploder pocket.

An igniter tube with four series of perforations extends down the center axis of the bomb and contains a celluloid tube holding a primed cambric tube. The igniter tube is held in place by the igniter tube holder, located in the center of the tail plate. The remainder of the bomb body is filled with three banks of smoke generators, each bank consisting of eight wedge shaped units fitted with drag plates.

A tail plate, to which is welded the fuze adapter. is secured to the inside of the after end of the bomb body by six brass rivets. A tail locating ring is fitted to the inside of the tail plate.

The Tail No. 81 Mk I consists of a cylindrical strut held in place on the truncated tail cone by four sheet metal fins. The tail is held in place on the bomb by the usual four spring clips, which engage in four similar recesses in the tail ring on the bomb body. A locating pin in the tail ring engages a slot in the bottom edge of the tail cone to position the tail.

This bomb is equipped for suspension in either British or American aircraft, having a single suspension lug on one side and dual lugs 180° removed.

Should water, especially sea water, come into contact with the smoke composition used in this bomb, the smoke composition is liable to spontaneous combustion due to chemical action.
