AVSC 3300 Module 1 Quiz
The core of the gas turbine that generates expanding gases required to produce thrust is known as? -
correct answer ✔✔The Gas Generator
What is the term used to describe a turbine engine that uses two compressors in tandem that are
mounted on separate shafts and turn a different speeds. - correct answer ✔✔Dual-compression engine
Axial-flow compressors are less fuel efficient than Centrifugal-flow compressors. - correct answer
✔✔False
What is the forward-most compressor of a dual-compressor engine referred to as? - correct answer
✔✔The low-pressure compressor
What is the objective of stator vanes in the compressor section of an axial-flow turbine engine? - correct
answer ✔✔To keep the airflow essentially parallel to the longitudinal axis of the engine between each
set of rotor blades
What is a diffuser in the compressor section of a turbine engine? - correct answer ✔✔A divergent duct
that slows the velocity of the impeller's output air, increasing the pressure before it enters the
combustion chamber
In a turbine engine, what drives the compressors by the use of shafts? - correct answer ✔✔Turbines
In a turbine engine, fuel is continuously sprayed into the_____and ignited, creating exhaust gases that
drive the turbines. - correct answer ✔✔Combustion Chamber
What is used to slow the velocity of the impeller's output air, and increases air pressure before it enters
the combustion chamber? - correct answer ✔✔A Diffuser
