Overall Flow Description
Refer to figure 2-12 while you are studying this
section on the inlet duct systems. It shows the CG,
DD, (minus the sand separators) intake
duct system. Intake air enters the main duct
through the demisters (moisture separators)
located in the sides of the high hat inlet. The air
flows down the main duct and passes through
silencers located about midway down the duct.
It then flows through a flexible coupling into the
engine inlet plenum. Cooling air taken off the
main duct ahead of the silencers flows through
the cooling duct, cooling duct silencers, and
cooling air fan. It then enters the engine enclosure
through a vent damper. The air circulates around
the engine and exits the enclosure through the
exhaust plenum. If the moisture separation system
becomes blocked, the blow-in doors automatically
open to supply the engine with combustion and
cooling air. Under these conditions, no demisting
protection exists.
High Hat Assembly
The high hat assembly (fig. 2-13) is located
on the 04 level of the ship. It houses all the
components of the moisture separation system.
MOISTURE SEPARATION SYSTEM.--
The moisture separation system includes the
