what are carbon seals used for in turbine engines?
they are used as oil seals for the rotor shaft bearings.
what determines the amount of airflow through a turbine engine?(3)
the forward speed of the aircraft, compressor speed, and air density.
name the two types of compressors commonly used in turbine engines.
axial and centrifugal flow compressors.
what are the different types of combustion chambers(4) used in turbine engines?
can, annular, can-annular, and reverse flow annular.
explain the main difference and advantage of turbofan over turbo jet engines.
a turbofan engine uses a fan to bypass some air around the engine core and to provide thrust. the advantage is that this provides additional thrust without increasing fuel flow.
how can you tell if a turbofan or turbojet engine is out of trim?
there will be high exhaust gas temperature at target engine pressure ratio for takeoff power.
name the different types of compressor blade damage that may be found during inspection(8).
