Engines Flashcards
What would alert the pilot to a transient/intermittent compressor stall?
Audible periodic “bang”
What will a pilot encounter when a compressor stall is fully developed?
Strong vibrations and loud roar
How should thrust reversers be applied to reduce landing distance for turbojet aircraft?
Immediately after ground contact
How are turbine engines classified?
The path the air takes through the engine and how the power is produced
A hot start in a turbine engine is caused by
too much fuel in the combustion chamber
With an increase in altitude in a turbojet aircraft, what happens to engine efficiency with regard to fuel burn?
Increases with altitude
What is the N(1) indication in a turbine-powered engine?
The rotational speed for the low pressure compressor
What is the N(2) indication in a turbine-powered engine?
The rotational speed for the high pressure compressor
If you exceed the rich limit of the fuel-air ratio in a turbine engine, you can expect it
will flameout
Compressor stalls are caused by
distorted airflow into the compressor section
What identifies a transient compressor stall.
Interment bang as backfires and flow reversals take place
A hung start in a turbine engine is caused by
insufficient starting power or fuel control malfunction
In a turbine engine, what would cause a compressor stall?
Compressor blades have exceeded their critical AOA
What is the appropriate action to take if a turbine engine is experiencing a steady state compressor stall?
Reduce power to reduce RPM
When landing, at what point should maximum reverse thrust be applied for maximum effectiveness?
As soon as the nose gear touches down
