empty space. As the inner drum moves the rounds or
spent cases toward the drum unload assembly, the scoop
disk assembly removes the rounds from the drum
partitions and places them into the retainer partitions of
the drum exit cover.
The drum unload assembly removes the rounds
from the retainer partitions and places them on the
unload tray. A hole in the unload tray lets spent cases
drop into a spent case container. Rounds are moved
across the hole in the tray to a live-rounds container.
These rounds must be restrained to prevent impact with
the container or other rounds.
In a load and/or download operation, any
combination of the following conditions may exist: A
fully loaded, partially loaded, or empty transporter
may be mated to a fully loaded, partially loaded, or
empty gun system. Each set of possible combinations
dictates a unique load and/or download operational
sequence. The load or download operational sequence
explained in the following paragraph refers to a
fully loaded transporter mated to a fully loaded gun
For you to load or download an aircraft gun
system, the conveyor system must be mounted on the
transporter with the timed entrance and exit unit
assemblies mounted to a timed drum. The timed
interface unit assembly must be mated to the timed
aircraft gun system by the aircraft adapter assembly.
The rounds pass from the transporter, through the
exit unit assembly, through an ammunition chute, to
the interface unit assembly. When the interface
unit assembly mode selector is in the bypass position
