ABSTRACT:
The Auto-destruct fuze is a mechanism that provides a primary mode detona and a delayed auto-destruct/self-neutralize mode detonator function for a grenade or similar munition. The mechanics for the primary mode detonation is similar to the M223 fuze which the present invention is designed to replace. Operation of the auto-destruct/self-neutralize mode is based on the working principles of the Liquid Annular Orifice Device (LAOD). The LAOD is released from a locked position upon expulsion of the device from a storage container. The LAOD moves slowly under the urging of a spring and eventually releases a cleanup firing pin which activates a cleanup detonator to auto-destruct or self-neutralize the grenade.
