Abstract
A fuse is used in a spin-type projectile. A percussion cap is mounted in a rotor which is normally disposed in a safety position. Rotation of the rotor to a firing position wherein the percussion cap is aligned with a firing pin is prevented by two independently operating safety devices prior to firing of the projectile. A first safety device comprises a conventional centrifugal mechanism which normally holds a bush within a recess of the rotor but releases same when the projectile spins. A second safety device comprises the firing pin which is urged into engagement with the rotor recess by a spring. An inertia disk is moved, in response to spinning of the projectile, to a position holding the firing pin out of engagement with the rotor recess. This enables the rotor to rotate to its firing position. When the projectile spin slows down or when the projectile impacts the target, the inertia disk can be moved aside as the firing pin enters the percussion cap.
