Abstract

A spinning projectile fuze contains a rotor which is retained by a safety spring in the form of a substantially ring-shaped disk in a safety or unarmed position. To enable the ring-shaped disk to release the rotor it must be pressed flat both by the firing acceleration and also by the spin. This ring-shaped disk possesses cut-outs or recesses by means of which it is subdivided into segments which are bent in an undulated or wave-shaped configuration.
