EXHAUST EJECTORSEXHAUST STACKS
The exhaust ejectors are part of the upper
engine cowling, and receive and direct the
exhaust gases rearward. Through venturi
action, 5% of the total flow through the
ejectors is cooling air drawn from the engine
compartments.
Two air intakes are built into each
lower engine cowl, to provide air for cooling. The
rear inlets supply air to the
oil cooler blowers, while the forward inlets direct ambient
air onto the engine gearbox cover mounted accessories. Airflow through each engine
compartment is provided by the action of the exhaust ejection system.
ENGINE COMPARTMENT COOLING
The engine exhaust stacks mount to the
top of the exhaust collector, and direct
engine exhaust gas upward and rearward,
into the exhaust ejectors.
