MARINE CORPS TM 6115-12/7
MAINTENANCE OF ENGINE
provides rotational-force at a constant
to drive the 10kW generator
mounted on the front of the gearbox.
In addition, the engine provides bleed
air to the air filter.
The engine is a
single-shaft design with the compressor
and turbine wheels mounted on a common
Air is drawn in through the
compressor air inlet, compressed by the
of the compressor
distributed to the outer chamber of the
The air then passes
through holes in the combustor liner
Fuel is atomized in the fuel
Injection nozzles, mixed with the air,
and injected into the combustor, where
expands rapidly and is forced through
the vanes of the turbine nozzle and
against the vanes of the turbine wheel
causing the turbine wheel to rotate.
Power produced by the rotating turbine
wheel is transmitted by the turbine
shaft to the generator drive assemblies
in the gearbox.
If not specified in
accordance with table 1-1,
object deflection shield
is limited to replacement.
