MIL-STD-2088 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

w/CHANGE 1

use of hearing protection, venting of the BRU pneumatic circuit shall not be a hazard for ground personnel, nor physically damage or functionally affect the surrounding structure and equipment. If a removable pressure vessel is used, the following safety aspects shall be addressed: The physical connection to or removal of a pressure vessel from the BRU pneumatic circuit, 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 E3 working group established in accordance with the requirements of

NAVAIR AR-43. The specifics for the EMC program effort shall be provided by the contractor and documented in the E3 Integration and Analysis Report (E3IAR) in accordance with

MIL-STD-464.

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, if applicable to the host program.

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.
