The dispenser assembly (fig. 10-19) contains two
major subassembliesa glass-reinforced phenolic
plastic block and a printed circuit board. The block has
30 holes so you can load the payload units. There are
four quick-release, positive-lock studs so you can
secure the block in the dispenser housing, and two
telescoping handles to make it easier to handle.
The printed circuit board contains the circuitry and
jacks so you can install 30 electrically initiated Mk 131
or CCU-63/B impulse cartridges. You must also install
a connector to act as an interface between the dispenser
assembly and the dispenser housing.
You load the dispenser by putting the 30 payload
units (in plastic sleeves with plastic cartridge retainers
installed) into the block. Install an impulse cartridge in
each of the 30 jacks on the printed circuit board. Then,
attach the board to the block by two captive screws.
NOTE: Installation of the impulse cartridges
must be accomplished in a designated RF
(radio frequency) free area.
Finally, install the loaded dispenser assembly in the
dispenser housing. You need to secure it with the four
positive-lock studs of the dispenser block. The payload
units are forced from the plastic sleeves by the gas
pressure generated when the impulse cartridges are
fired. The chaff sleeve extractor, shown in figure 10-19,
is used during dispenser download procedures.
