DESCRIPTION. This fuze is housed in the radio comparment of the HS 293 immediately to the rear of the warhead. It is a sensitive "all-ways" action impact fuze and its only function is to destroy the radio equipment. (See fig. 190.)

The fuze is constructed so as fit into the standard fuze pocket. The fuze body is threa-ded internally at the base to take a standard gaine and externally to take the charge case which is filled with pentrite wax (approximately 6 ounces).

A chamber machined through the lateral axis of the fuze accommodates the striker as-sembly. The inner wall of this chamber is a concave truncated cone against which the detonator holder bears.

The striker assembly consists of the striker body, striker needle, creep spring and deto-nator holder. The head of the striker body is conical in shape and bears against the cir-cular closing cap which is positioned in the mouth of the machined chamber.

When the striker assembly is assembled in the fuze, the striker body patially enters the detonator holder and is retained clear of the detoantor by means of the creep spring.

A safety feature is incorporated by means of a striker detent. A detent retainer, one end of which is attached to a wheel in the clockwork mechanism, keeps the striker detent in position until approximately 5 seonds after the bomb leaves the aircraft. The clockwork regulates the length of arming time.

OPERATION. When the bomb is released from the aircraft, an arming link or static cord pulls out the safety pin which locks the striker detent retainer. On this action the exten-ded spring attached to the striker detent retainer exerts its force upon the retainer mov-ing it clear of the striker detent. The speed at which this takes place is governed by the clockwork gear train. When the retainer is clear of the striker detent, the detent spring forces it away from the striker assembly.

The fuze is now armed with only the creep spring maintaining the striker clear of the de-tonator cap. On impact, the striker body moves forward against the creep spring and the point of the striker impinges upon the detonator firing it. The flash passes through the channel as shown and sets off the gaine and then the main charge; the main charge consisting of the penthrite wax in the container around the gaine.
