placed in the 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.

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 combination dictates a
unique load and/or downloads 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 system.
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
