| Description: |
|---|
| The bomb consists of a square-section, tin-plate, 5-galIon, petrol can. On one face are two corrugated stiffeners which serve to increase the strength of the can and also act as distance pieces between the can and the drop bar of the Small Bomb Container in which the bomb is carried!, A charging hole, with screwed cap and washer, and another distance piece are provided at the top of the can. At diagonally opposite corners on the top of the can are two metal loops for attachment of the 12-in. by 21-in. fabric tail, which acts as a flight stabilizer. Two handles for lifting the bomb are soldered to opposite faces of the can. Bombs of later issue may have a third handle, located on the face, to which the stiffeners are soldered, |
| Use: |
|---|
| Incendiary bombs of many various types, ranging in weight from 4 to 2o0 lb., are at pres¬ent in service use for operations against dif¬ferent types of targets. The Construction and filling of these bombs differ with the individual types, and no general description can be given here to cover the complete range. |
| Functioning: |
|---|
| The bomb is fuzeless and functions by break-up. The igniter consists of droplets of a liquid which reacts with water to produce small sparks. The liquid is dispersed in a thick oil, which floats on water. The sparks produced are not sufficient to ignite fuel oil Or paraffin, but ignite petrol im¬mediately. Thus, when the K.O.F.Q.R. and petrol charging is released on impact of the bomb with the surface of the water, the K.O.F.Q.E. ignites the petrol, which ignites the layer of on floating on the water. |
