The BRU-11A/B bomb ejector rack (fig. 8-32) has
four suspension hooks. Two of these hooks are spaced
14 inches apart and two are spaced 30 inches apart.
These hooks carry weapons/stores weighing up to
4,000 pounds. The rack has electrical connections,
mechanical and electrical arming units, ejection
components, and mechanical linkage for safely
suspending and ejecting weapons/stores.
When the pilot fires the impulse cartridges, the
resulting gas pressure unlocks the suspension hooks.
The gas pressure simultaneously causes the ejection
piston and ejector foot to kick the weapon/store away
from the aircraft. The BRU-11A/B has a secondary
weapons/stores jettison release if the primary system
fails. The secondary release also uses an impulse
cartridge to unlock the suspension hooks, but it does not
eject the weapon/store.
