Abstract
44A fuze is provided for projectiles of the nonspinning and slow spinning types which possess a rotor that carries a detonator, and a first safety device preventing the rotor from bringing the detonator to an active position. The first safety device is responsive to acceleration force when the projectile is fired, to release the rotor for at least limited rotation. A second safety device permits only limited rotation of the rotor unless released. Release of the second safety device occurs in response to retardation of the fired projectile after the latter leaves the barrel and encounters air resistance. Release of the second safety device is possible only after a predetermined amount of rotation of the rotor when a locking bolt of the second safety device becomes aligned with an orifice in a stationary frame that mounts the rotor. The bolt whose mass is tuned to the retardation characteristics of the projectile, then travels through the orifice in the direction of acceleration to release the rotor for final travel.
