BRU-15/A BOMB RACK

The BRU-15/A bomb rack (fig. 10-10) is installed on the wing stations of the P-3B and P-3C aircraft. It is

used with the aircraft wing store launcher assembly, which is modified to launch a Harpoon missile. You can attach Aero 1A adapter assemblies to increase the bomb rack to 30-inch suspension capacity. Because of the added Harpoon capabilities, the BRU-15/A replaces the Aero 65A as wing suspension racks for the P-3C aircraft.

The BRU-15/A bomb rack is a modification of the BRU-14/A bomb rack. The functional and physical characteristics of the BRU-15/A are shown below. The IFOBRL mechanism and associated

auxiliary unlock device are not included.

There is a safety mechanism to positively lock the release mechanism of the bomb rack when a safety pin is installed. There is a cable-actuated manual release mechanism that operates the primary release linkage through an added manual release cable and lever.

When in flight, today's high-speed fighter and attack aircraft create a vacuum under the fuselage and wings. If a weapon/store is released from the bomb rack, this vacuum can prevent the weapon/store from entering the airstream and falling to the target. If this happens, the weapon/store may physically contact the aircraft structure, causing serious damage to or loss of the aircraft.

Bomb ejector racks are different from bomb racks. Bomb ejector racks use electrically fired impulse cartridges to eject the weapon/store free of the bomb racks. Bomb ejector racks eject the weapon/store from the bomb rack with sufficient force to overcome vacuum buildup and ensure a safe weapon/store launching environment.

AERO 7A-5 AND AERO 7B-4 BOMB EJECTOR RACKS

The Aero 7A-5 and Aero 7B-4 bomb ejector racks are mounted externally on the A-6 aircraft. All EA-6 aircraft models are equipped with an Aero 7B-4 ejector bomb rack on the centerline station and an Aero 7A-5 bomb ejector rack on the wing stations. These bomb ejector racks make up the aircraft's basic weapons suspension. They are normally referred to as parent racks. Bomb ejector racks are mounted in fairingenclosed pylons for aerodynamic purposes. The pylons have removable fairings and hinged doors for easy access to the components of the bomb ejector racks.

Aero 7A-5 Bomb Ejector Rack

The Aero 7A-5 bomb ejector rack assembly (fig. 10-11) consists of a housing that contains the following components:

Four pairs of tandem suspension hooks

A dual breech assembly

Mechanical linkage connecting the hook sears to the ejector and manual release assembly

An electrical junction box connecting the aircraft firing pulses to the breech

Two sets of adjustable sway braces

Mechanical and electrical arming units

There are four separate pairs of suspension hooks on the Aero 7A-5 bomb ejector rack-two pairs for 14-inch suspension and two pairs for 30-inch suspension. The suspension hooks are self-latching,
