The HTARS is a kit that consists of enough hoses, fittings, and nozzles (Figure 4-1) to expand the HEMMT
tanker's capabilities to hot refuel up to four helicopters simultaneously using the on-board fuel-servicing
pump. The equipment is lightweight, has manually operated controls, and is equipped with valved and
swivel adapters that allow connections between camlock and unisex type fittings. This equipment can be
used in forward areas. It can be transported in the storage box of the HEMTT tanker.
PART A - EQUIPMENT
Discharge Hoses. The system consists of both 2- and 3-inch discharge hoses. One 3-inch by 50-foot
hose is used to connect the HTARS to the HEMTT tanker. Ten 2-inch by 50-foot discharge hoses transfer
the fuel from the HEMTT tanker to the aircraft. Six hoses are used in the manifold and one in each of the
four issue lines. There are 11 carrying straps for easy handling of rolled hoses.
Valves and Fittings. The following valves and fittings are components of the HTARS:
Three T-connectors with a flow control handle to open and close the valve. The T-connector splits the
flow of fuel.
Two elbow connectors to direct the flow of fuel.
Three valved adapters to connect threaded and unisex parts as well as camlock and unisex parts.
One swivel adapter to connect camlock and unisex parts.
Nozzles. The HTARS is equipped with four types of nozzles. There are four CCR nozzles with unisex
adapters. Four overwing nozzles can be mated to the CCR nozzles to perform open-port refueling. The
system has one recirculation nozzle that can be connected to the HEMTT tanker to recirculate fuel in the
system. It is equipped with a fuel sample port to obtain a sample of fuel. The recirculation nozzle mates to
the CCR nozzle. There are four D-1 nozzles to equip the system for center-point refueling.
Overpack And Other Required Items. Each system has one overpack spare with additional parts
and accessories. The following parts are in the overpack spare: one T-connector, one 2-inch by 50-foot
discharge hose, one carrying strap for easier handling of the rolled hoses, 10 dust seals, two dust caps, and
four grounding rods.
Other items of equipment are required to conduct aircraft refueling operations with the HTARS. A
minimum of five fire extinguishers are required, one to be within reach of the on-board pump and one at
each refueling point. Signs will need to be posted at the refueling site. Also, water cans and spill containers
will need to be available.
