Device for selbsttaetigen unlock the ignition system under utilization of rotation which occur when a projectile is fired heavy

摘要

A projectile fuse has two activating devices acting independent of each other. One of the devices includes a plurality of wafer-like sectors which are retained together as a unitary disk by means of a coil spring having 1.5 to 2 convolutions. The disk is arranged in a bore of the fuse housing and normally covers a vent which is concentrically positioned in the bore. Under the effect of rotationally generated centrifugal forces occurring upon firing, the sectors force open the spring and thereby expose the vent for passage of an ignition flash.
