MIL-STD-2088-SUP-2 Bomb Rack Unit BRU, Single Store, AircraftThis standard establishes the general guidelines and criteria for the design and development of a single store bomb rack unit BRU for carriage and release of airborne stores excluding air-to-air missiles from fixed wing and rotary wing aircraft using a single suspension point or suspension points spaced at 14 or 30 inches. This standard addresses detailed requirements for gravity non-ejected, pyrotechnic, hydraulic, and pneumatic powered BRUs. Mechanical aircraft armament interoperable interfaces are incorporated to enhance cross utilization and servicing capabilities between military aircraft and aircraft stores see 3.1 of all services of the Department of Defense DoD and North Atlantic Treaty Organization NATO nations.

MIL-STD-2088B

irrespective of its charge level, shall not represent a hazard for ground personnel and shall not physically damage or affect the functionality of surrounding structure and equipment. A built-in safety feature shall exist to prevent the actuation of the pneumatic connection before the

reservoir is safely restrained. The physical removal of the reservoir shall not produce unintended venting or recoil action. If, in order to obtain a safe disconnect, venting is needed at either side

of the pneumatic interface, then a built-in safety feature shall exist to prevent the disconnection until either side is safely vented. Should the BRU inadvertently "fire" during loading and unloading of stores with its pressure vessel charged, all driven items, such as ejectors, shall be precluded from injuring ground personnel or damaging equipment or the aircraft.

5.1.9 Electromagnetic environmental effects (E3). The control of E3 shall be as specified in

5.1.9.1 through 5.1.9.9.

5.1.9.1 Electromagnetic compatibility (EMC) program. A system EMC program in accordance with the requirements of MIL-STD-464 shall be applied. This program shall be supported by an Electromagnetic Compatibility Advisory Board (EMCAB) established in accordance with the requirements of NAVAIR AR-43. The specifics for the EMC program effort are provided in the Electromagnetic Compatibility Program Plan (EMCPP).

5.1.9.2 Electromagnetic interference (EMI). The BRU electrical system shall meet the requirements of MIL-STD-461 Class Alb and MIL-STD-464. For U.S. Army Aviation, the requirements of ADS-37A-PRF, Table 1, parts A and B shall be met.

5.1.9.2.1 Electromagnetic pulse (EMP). The BRU shall meet the EMP requirements of

MIL-STD-464.

5.1.9.3 Electromagnetic vulnerability (EMV). The BRU electrical system shall meet the EMV requirements of MIL-STD-464. For U.S. Army applications the system shall also meet the requirements of ADS-37A-PRF.

5.1.9.4 Lightning protection. The BRU system shall meet the requirements of the EMC program to provide compliance with the requirements of MIL-STD-464 for protection against lightning.

5.1.9.5 Bonding and grounding. The BRU system shall meet the requirements of the EMC

program to provide compliance with the requirements of MIL-STD-464.

5.1.9.6 Wiring and cabling. The BRU shall meet the requirements of the EMC program to provide compliance with the requirements of SAE-AS50881.

5.1.9.7 Static electricity. The BRU system shall meet the requirements of the EMC program to provide compliance with the requirements of MIL-STD-464 for static electricity effects.
