Fuze Well Mechanical Interface
This interface standard applies to fuzes used in airborne weapons that use a 3-in fuze well. It defines: - Physical envelope of the fuze well at the interface with the fuze. - Load bearing surfaces of the fuze well. - Physical envelope of the fuze and its connector. - Mechanical features (e.g., clocking feature). - Connector type, size, location and orientation. - Retaining ring and its mechanical features (e.g., thread, tool interface). - Physical envelope of the retaining ring at the interface with the fuze. - Physical space available for installation tools. - Torque that the installation tool shall be capable of providing. This standard does not address: - Materials used or their properties. - Protective finish. - Physical environment of the weapon. - Explosive interface or features (e.g., insensitive munitions (IM) mitigation). - Charging tube. - Torque on the retaining ring or loads on the load bearing surfaces.
