SCOPE1.1 ScopeThis standard defines implementation requirements for the electrical interface between: a. aircraft carried miniature store carriag
21、e systems and miniature storesb. aircraft parent carriage and miniature storesc. surface based launch systems and miniature storesThe interface provides a common interfacing capability for the initialization and employment of smart miniature munitions and other miniature stores from the host systems
22、. Physical, electrical, and logical (functional) aspects of the interface are addressed.1.2 PurposeThe purpose of this standard is to minimize proliferation of electrical interfaces between platforms, miniature stores and associated carriage systems and thereby promote interoperability of miniature
23、stores and carriage systems across different programs and services.1.3 ApplicationThis standard applies to all platforms, miniature stores and associated carriage systems that electrically interface with each other. The carriage systems include captive and releasable (canister type) aircraft mounted
24、 carriage devices, platforms such as unmanned combat air vehicles (parent carriage), dedicated carriage areas on aircraft, and surface based launch systems. For simplicity within this document, all carrying devices are generically referred to as the miniature store carriage system (or simply carriag
25、e system) from an interface perspective. Additionally, the term store as used in this document refers to a miniature store unless otherwise indicated.2.

36、3.1 DefinitionsDefinitions applicable to this standard are as follows.3.1.1 AIRCRAFTAny vehicle designed to be supported by air, being borne up either by the dynamic action of the air upon the surfaces of the vehicle, or by its own buoyancy. The term includes fixed and movable wing airplanes, helico
37、pters, gliders, and airships, but excludes air-launched missiles, target drones, and flying bombs.3.1.2 ELECTRICAL INTERFACE TYPESThe two electrical interface types for the carriage system/store electrical interconnection system shall be as specified below.3.1.2.1 MINIATURE STORE CARRIAGE INTERFACE
38、(MSCI)The electrical interface on the miniature store carriage system structure where the miniature mission store is electrically connected either directly (blind mate) or via an interconnecting umbilical cable.3.1.2.2 MINIATURE MISSION STORE INTERFACE (MMSI)The electrical interface on the miniature
39、 mission store external structure or interconnecting umbilical cable that mates withan MSCI interface on the carriage system.3.1.3 MINIATURE STORE CARRIAGE SYSTEMA system which provides for carriage and release of and electrical interfacing to miniature munitions or other stores that are compliant w
40、ith the miniature store electrical interface standard defined in this document. The miniature store carriage system may be located external to the aircraft in a separate enclosure (possibly releasable) which is electrically interfacedto the aircraft via a MIL-STD-1760 compatible interface, or may be
41、 integrally contained within the structure of an unmanned or manned aircraft platform, or may be included in surface based launch systems. The miniature store carriage system is typically referred to simply as the carriage system in this document.3.1.4 STOREAny device intended for internal or extern
42、al carriage and mounted (either directly or through an intermediary carriage device) on aircraft suspension and release equipment, whether or not the item is intended to be separated in flight from the aircraft. Stores relevant to this standard are miniature stores classified in two categories as sp
43、ecified below. (Note that the generic term store is typically used to refer to miniature stores in this document when the distinction of category is notimportant.)3.1.4.1 MINIATURE MISSION STOREA small munition or other store with an MMSI carried at a station on a miniature store carriage system.3.1
44、.4.2 SUBPACKAn in-flight separable physical package which contains multiple miniature mission stores intended for release as a single entity (for aerodynamic purposes, etc.) from a carriage system. Subpacks provide individual external MMSIs for each carried miniature mission store. A separate extern
45、al MMSI may additionally be provided (as required) on each subpack for interfacing to internal subpack electronics.SAE INTERNATIONAL AS5725B Page 7 of 533.1.5 STORES MANAGEMENT SYSTEMThe avionics subsystem which controls and monitors the operational state of aircraft installed stores and provides an
46、d manages the communications between aircraft stores and other aircraft subsystems.3.1.6 SUSPENSION AND RELEASE EQUIPMENTAll airborne devices used for carriage, suspension, employment, and jettison of stores, such as, but not limited to, racks, adapters, launchers, and pylons.3.1.7 DELAYSignal or da
47、ta delay is the elapsed time between the input stimulus and output response of a particular signal or data path.3.1.8 POWER INTERRUPTIONAn excursion of supplied interface power below the specified normal steady state limits established by this standard.3.1.9 L1_P(Y) SignalThe L1_P(Y) signal is the G
48、PS L1p carrier component of L1, bi-phase shift key (BPSK) modulated by the P(Y) code plus data bit stream, as described in STANAG 4294.3.1.10 L2_P(Y) SignalThe L2_P(Y) signal is the GPS L2p carrier component of L2, bi-phase shift key (BPSK) modulated by the P(Y) code plus data bit stream, as describ
49、ed in STANAG 4294.3.1.11 L1_C/A SignalThe L1_C/A signal is the GPS L1c carrier component of L1, bi-phase shift key (BPSK) modulated by the C/A code plus data bit stream, as described in STANAG 4294.3.1.12 FIBRE CHANNELFibre Channel is the name for a high-speed network standard. Fibre Channel allows for both copper and fiber optic implementations.3.1.13 SAFETY CRITICALAn interface operation (electrical, logical or a combination of both) at
