Section III. PRINCIPLES OF OPERATION
1-12. SYSTEM TECHNICAL PRINCIPLES OF OPERATION.
NOTE
The AFSSP module described in this manual is configured for a typical mission. Your
specific mission and operating requirements will determine how many of the system
components must be connected and in what configuration. The type of fuel nozzle used at
the offloading points will be determined by the type of equipment being refueled.
a.
The Arctic Fuel System Supply Point (AFSSP) module is comprised of three tanks, manifolds, two turbine
powered fuel pump, three 200 GPM filter separators, pressure reducing valves, five types of refueling nozzles
and the necessary hoses and valves required to assemble and distribute fuel through the system. Fuel is
received from tank trucks to fill the storage tanks. Fuel is removed from the 3,000, 10,000 or 20,000 gallon tanks
and delivered to the required equipment. Fuel offloading can be accomplished at the refueling, drum filling or
bottom loading points. Fuel can bypass the storage tanks and pump directly from the tank trucks to the
dispensing points.
b.
Fuel required to operate the AFSSP is stored in three collapsible tanks. The tanks expand as they are filled and
collapse as they empty. Each tank is connected to the AFSSP module by two manifolds. As the manually
operated gate valve is opened, fuel is allowed to flow to or from the tank. For additional information on principles
of operation for the collapsible tanks, refer to TM 10-5430-231-12.
c.
Fuel flows from the 3,000, 10,000 or 20,000 gallon tanks, through 6-inch hoses, to the manifold. One or two hand
operated valves are installed on the manifold to direct fuel flow through the manifold. The manifold directs fuel
from the 3,000, 10,000 or 20,000 gallon tanks to the 600 GPM pump for distribution to the equipment.
d.
The turbine powered 600 GPM pump supplies fuel to the tanks and supplies fuel under pressure to the skid
mounted filter separator. For additional information on principles of operation for the 600 GPM pump, refer to
TM 10-4320-342-10.
e.
Fuel from the 600 GPM pump is processed by the filter separators to remove solid contaminants and water from
the fuel before delivery to the equipment. For additional information on principles of operation for the filter
separator, refer to TM 10-4330-236-13.
f.
Clean fuel from the filter separator is distributed through 1½ , 3 or 4-inch discharge hoses to the Arctic Nozzle,
Tank Coupler or a Ball Valve. A Closed Circuit Refueling Nozzle (CCR) with gravity fill adapter and a Single
Point Refueling Nozzle (D1) are also provided as accessories to further enhance the versatility of the system.
