Fuzing: None. Float ignited by chemical reaction between calcium phosphide and water.

CONSTRUCTION. The body is made of two hollow cylinders welded together. (See fig. 93.) The nose is welded to the body and is provided with a welded collar which is threa-ded to receive either a nose plug or a suspension lug. Just forward of the normal suspen-sion lug is an inset similar to a Rheinmetal fuze head. Four sheet steel fins form the tail. Projecting from the base is a small compartment around which the silk mooring cord may be coiled. Two wooden grips are attached to this cord. Two winged nut screw plugs are fitted on opposite sides of this compartment giving access to the bouyancy compart-ment. Internally the float is divided into six compartments – the calcium carbide contai-ner, the acetylene gas compression chamber, the calcium phosphide chamber, the buo-yancy chamber, the water inlet chamber, and the combustion chamber. On leaving the aircraft, a rubber bung is withdrawn by pulling the arming wire. The float sinks below the surface on its initial dive and water enters the ports and passes down the inlet tube into the calcium phosphide chamber thus generating phosphine. The phosphine passes up the outlet tube through the nonreturn valve to the burner where it ignites spontaneously to form a pilot jet. At the same timer water enters through the channels in the nose and passes through a perforated tube into the carbide compartment. The acetylene evolved passes through the perforated diaphragm into one compression chamber and thence to the burner where it is ignited by the pilot jet.

According to the instructions stenciled on the body the float, once it has served its pur-pose, should be sunk by removing the winged nut screws which permits the buoyancy chamber to fill with water.
