ABSTRACT:
An impact fuse for a projectile comprises a firing needle and a main detonator carried by a rotor. The rotor is rotatable about an axis, upon launching of the projectile, and is rotated by centrifugal force from a safety position to a firing position in which the firing needle is aligned with the main detonator. Upon target impact, the rotor is displaced axially to cause the firing needle to detonate the main detonator. Acceleration forces occurring upon launching cause a piercing pin to activate a delay detonator. After a pre-selected time delay, the activated delay detonator emits a gas which displaces the rotor axially and produces detonation of the main detonator, in the absence of target impact.
