Turbine Engines Study Exam Questions
Correctly Answered.

1. What are the two basic sections of a turbine engine? - CORRECT ANSWER The hot section and the cold
section.



2. What are the two basic types of compressors that are used in aircraft turbine engines? - CORRECT
ANSWER Axial-flow and centrifugal.



3. What is the purpose of the stators in an axial-flow compressor? - CORRECT ANSWER The stators
convert some velocity energy into pressure energy and change the direction of the air so it is proper for
the next stage of rotors.



4. What are three types of combustors used on aircraft turbine engines? - CORRECT ANSWER Can-type
annular-type and can-annular-type.



5. How many igniters are there normally in an aircraft turbine engine? - CORRECT ANSWER Two.



6. What is the main purpose of the turbine nozzle in an aircraft turbine engine? - CORRECT ANSWER The
turbine nozzle directs the hot gases as they leave the combustors so they will turn the turbine wheel
with maximum efficiency.



7. What is meant by a free-turbine turboshaft engine? - CORRECT ANSWER A turboshaft engine that has
a turbine wheel or stage of turbine wheels that is not used to drive the compressor of the gas generator
section of the engine. This free turbine drives the propeller in a turboprop engine or the transmission
and rotor of a helicopter.



8. Why do some axial-flow turbine engines have more than one set of turbines and compressors? -
CORRECT ANSWER A two-spool turbine engine has a low-pressure and a high-pressure compressor each
driven by its own turbine. The two independent systems operate at the speed at which they are most
efficient.
