Abstract:

The patent relates to a safing and arming mechanism which is adapted for use with a mechanical fuze, and which is armed only after having been subjected to the combined and total effects of a spin environment. The mechanism includes a rotor and a rotor spring which will arm the mechanism only at a higher static spin rate than a lockweight component of the mechanism. Because of a delay disc-lockweight interlock structural feature, the complete arming sequence of the mechanism is prevented until the necessary spin and deceleration environments exist. When this environmental combination is achieved, the lockweight moves before the rotor can return and that results in the release of the rotor and the arming of the mechanism.
