container. Unfired rounds continue further upstream
into the unfired round tray where they are manually
placed into an ammunition container
Aircraft Servicing Mode
The M61A1/A2 aircraft gun system can be
serviced while simultaneously removing expended
casings and unfired rounds. To service the aircraft gun
system, the Aircraft Gun Feed System (AGFS) must be
timed. The AIU is positioned to provide operator crew
access. The AIU shift lever handle is placed in the down
(BYPASS) position, the manual drive knob is rotated to
align the AIU to the timed position and the timing pin is
engaged. The AIU is then attached to the AGFS and the
timing pin is disengaged. The AIU shift lever handle is
then placed in the up (LOAD) position. A hand crank or
pneumatic drive tool is attached to the AGFS gun drive
socket and is used to cycle the ammunition through the
storage container assembly into the aircraft gun
systems. As the rounds from the three bays in the loader
travel through the terminal drive sprockets, they are fed
into the lower half of the transfer unit. All three streams
of ammunition are merged and accelerated into a single
stream of ammunition.
From the transfer unit assembly, the ammunition is
driven through the lower half of the conveyor chute
assembly into the aircraft interface unit and is passed
into the aircraft gun system. At the same time, unfired
rounds and spent cases are downloaded through the
upper rotor of the aircraft interface unit into the upper
half of the conveyor chute assembly. At the transfer unit
assembly, the single stream is decelerated, divided into
three streams and transferred into the three bays of the
storage container assembly.
REVIEW NUMBER 2 ANSWERS
operations are conducted, they must be done
in an RADHAZ-free environment.
In a given load/download operation, any of
the following conditions may exist: A fully
transporter may be mated to a fully loaded,
partially loaded, or empty gun system.
When you connect or remove the interface
unit to or from the aircraft adapter, it must be
in the bypass position.
In the transport mode, the ammunition loader is
used to transport ammunition from the magazine to the
aircraft. It can be mounted on a variety of transporter
and trailers. A forklift truck can be utilized to move the
ammunition loader short distances. Forklift guides are
an integral part of the mounting base assembly. When
ashore, the ammunition loader will be transported
MHU-151/M or MHU-202/M trailers. Afloat, the
replenisher (fig. 7-24) will be stored in a designated
storage area. The ammunition loader and ammunition
replenisher must be empty of all ammunition and spent
cases. To ensure the ammunition loader is empty, one
marked dummy round is cycled completely through the
storage container assembly, transfer unit assembly and
conveyor assembly. A dummy round will also be cycled
through the ammunition replenisher prior to storing it.
The ammunition loader can be moved to the designated
storage area with a forklift or a chain hoist and rail
system. A lifting beam mounted in the ammunition
loader is used to attach the ammunition loader to the
chain hoist. The lifting of the ammunition loader should
be accomplished by at least two personnel to ensure the
ammunition loader is under control at all times. Both
the ammunition loader and the ammunition replenisher
are secured to the deck using tie-downs.
