in the normal release mode. The auxiliary unlock
assembly is a cartridge-actuated device (CAD) that
provides a mounting point for the aft end of the
IFOBRL. When actuated, the unlock assembly releases
the IFOBRL and allows it to move forward. This frees
the sear link from restraint and lets the rack linkage
function normally.
The BRU-14A bomb rack has a secondary release
assembly. It initiates hook release if the LEMA fails to
function. The secondary release assembly is a CAD that
consists of a housing, piston, and release slider
assembly mounted on the top of the bomb rack frame.
When actuated, the secondary release moves the sear
link forward to release the bomb rack. The BRU-14/A
doesn't have remote manual-release capabilities.
If you want more information about the BRU-14/A
bomb rack, refer to Bomb Rack BRU-14/A and
BRU-15/A, NAVAIR 11-5E-18.
BRU-15/A BOMB RACK
The BRU-15/A bomb rack (fig. 10-4) is installed
on the wing stations of the P-3 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.
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.

aircraft?

BOMB EJECTOR RACKS
LEARNING
OBJECTIVE:
Identify
the
purpose and use of bomb ejector racks to
include
their
principles
of
operation,
maintenance requirements, and operational
description.
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
