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.

3.    DEFINITIONS

3.1  Aircraft store.  Any device intended for internal or external carriage and mounted on aircraft suspension and release equipment, whether or not the item is intended to be separated in flight from the aircraft.  Aircraft stores are classified in two categories as follows:

a.  Expendable store. An aircraft store normally separated from the aircraft in flight such as a missile, rocket, bomb, nuclear weapon, mine, torpedo, pyrotechnic device, sonobuoy, signal underwater sound device, cargo drop container, drone, and other similar items.

b.  Non-expendable store. An aircraft store that is not normally separated from the aircraft in flight such as a tank (fuel and spray), line source disseminator, pod (refueling, thrust augmentation, gun, electronic-countermeasure, data link), multiple rack, target, and other similar items.

3.2  Bomb Rack Unit (BRU).  Suspension equipment used for carrying aircraft store(s) that incorporates a method of separating the aircraft store from the aircraft at the time of commanded release.

3.3  Burst pressure.  Design test pressure aimed to verify the structural integrity of the pressure system.  Permanent deformation and leakage are permitted when burst pressure is applied, but no sudden ruptures or detachment of parts are allowed.

3.4.  Ejections.  The number of powered store releases or separations.

3.5  Flight hours.  The number of hours accumulated in the airborne condition.
