BRU-41 Multiple Ejector Rack (MER)

The Multiple Ejector Rack (MER) is a weapon suspension unit that attaches to an aircraft's main racks (pylons), and that can carry up to six weapons, such as the Mk-20, Mk-82 Slick, Mk-82 Snakeye, CBU-87, or CBU-97. The Air Force stopped using MERís in the early 1990ís, and is currently only using the TER triple-rack. The MER (A/A37B-6E) is an accessory suspension aircraft armament equipment which attach to a parent rack. The MER consist of an adapter assembly (strong back) tsix ejector units, a wiring harness, and an aircraft hardware adapter kit. The MER is capable of carrying as many as six stores attached to the ejector units (i.e. BRU-20 Ser. or MAK-79). Each ejector unit has four adjustable sway braces and two mechanically locking suspension hooks spaced 14 inches apart. Bombs are suspended and attached to the Multiple Ejector Rack by two suspension lugs 14 inches apart [except the Mk 84 which had lugs 30 inches apart]. Release was achieved by firing a charge that actuated a piston that forced the bomb off the MER. Each ejector unit is equipped with a safety stop lever located on the rear sway brace assembly which, when rotated to the locked position, prevents accidental stores release. The improved MER (BRU-41) has been introduced to the fleet to replace the MER. This rack incorporates internal modifications that improve bomb rack reliability and maintainability. The improved multiple ejector rack also incorporate an electronic control unit which controls all bomb rack functions.
