What are the engine cowlings
|
Metal panels that cover the engine compartment
|
|
What does the engine cowling do
|
Protects engine componentsDecreases dragProvides an engine air intake
|
|
Are the engine cowlings removable
|
Yes all are removable, most can be opened with quick release latches to allow access to the engine compartment
|
|
Where does airflow enter the cowling
|
Through an opening in the fron just below the nose piece
|
|
What does the inertial separator do
|
Causes the air molecules to turn 90 degrees to enter the engine compartment. Heavier particles such as water and debris can not make turn and are returned to atmosphere through a bypass duct
|
|
How does the T-6 engine produce thrust
|
By turning the propeller
|
|
Where are the major components of the engine located
|
 |
|
What is the engine in the T-6A
|
Pratt and Whitney PT-6A-68 Free turbine, reverse flow design, turboprop
|
|
What does free turbine mean
|
The compressor and power turbines are not physically connected. Air movement from one turbine powers the other
|
|
What does reverse flow mean
|
The airflow through the engine is in reverse. It enters in the rear and moves forward through the combustion cycle
|
|
What are the three elements necessary for engine operation
|
Air - (Starter initial, then compressor)Fuel - Fuel Management Unit (FMU)Heat - Ignition System
|
|
What are the 3 major sections of the engine
|
Acessory Compartment - Accessory Gearbox, Oil Tank, Starter/Generator, BatteryGas Generation section - Compressor Inlet, Compressor, Combustion Chamber, Compressor TurbinePower Turbine Section - Power Turbines, exhaust case, reduction gearbox, propeller shaft
|
|
Where is the accessory compartment located and what does it contain
|
Location: RearContains: Accessory Gearbox, Oil Tank, Starter/Generator, Battery
|
|
What is the one component in the accessory compartment directly related to engine operation
|
Starter - It turns the compressor turbine and compressor which provides air to the engine unitl it starts and can sustain itself
|
|
Where is the gas generation section and what does it contain
|
Location: MiddleContains: Compressor Inlet, Compressor, Combustion Chamber, Compressor Turbine
