This document establishes techniques for validating that a mission store complies with the interface requirements contained in MIL-STD-1760 Revision D.

This SAE Aerospace Information Report (AIR) will examine network aspects of open and shorted stubs, line reflections and bus loading due to network changes. Single network level is assumed, that is, no carriage store hierarchical levels. However, two passive network coupling variants called "branched bus" and "branched stub" will be introduced that possibly could be used in a stores management network. This report assumes familiarity with MIL-STD-1553B.

This document was prepared by the SAE AS-1B1 IMM Task Group to explain and document background information and design decisions made during the development of AS5726. This handbook is published separately to preserve information that is not required or provided in the AS5726 but may be important to system designers to ensure interoperability between the Micro Munition Host and Micro Munition. As a handbook, it cannot be invoked as a requirement in a contract. The structure and numbering of this document mirrors that of AS5726 for the convenience of readers. Headings such as “Requirements” in this handbook should not be interpreted as invoking requirements.

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.

This standard only defines interconnect, electrical and logical (functional) requirements for the interface between a Micro Munition and the Host. The physical and mechanical interface between the Micro Munition and Host is undefined. Individual programs will define the relevant requirements for physical and mechanical interfaces in the Interface Control Document (ICD) or system specifications. It is acknowledged that this does not guarantee full interoperability of Interface for Micro Munitions (IMM) interfaces until further standardization is achieved.
