Turbine Engines-Power Plant Written
Exam Questions Correctly Answered.

1 (8108) - At what point in an axial-flow turbojet engine will the highest gas pressures occur? - CORRECT
ANSWER C- At the compressor outlet.



2 (8109) - One function of the nozzle diaphragm in a turbine engine is to - CORRECT ANSWER C- Direct
the flow of gases to strike the turbine blades at the desired angle.



3 (8110) - What is the profile of a turbine engine compressor blade? - CORRECT ANSWER B- A reduced
blade tip thickness.



4 (8111) - The fan rotational speed of a dual axial compressor forward fan engine is the same as the -
CORRECT ANSWER A- low-pressure compressor.



5 (8112) - The abbreviation Pt7 used in turbine engine terminology means - CORRECT ANSWER C- the
total pressure at station No. 7.



6 (8113) - The blending of blades and vanes in a turbine engine - CORRECT ANSWER B- should be
performed parallel to the length of the blade using smooth contours to minimize stress points.



7 (8114) - What turbine engine section provides for proper mixing of the fuel and air? - CORRECT
ANSWER A- Combustion section.



8 (8115) - In a gas turbine engine, combustion occurs at a constant - CORRECT ANSWER B- pressure.



9 (8116) - Which statement is true regarding jet engines? - CORRECT ANSWER B- At the higher engine
speeds, thrust increases rapidly with small increases in RPM.

, 10 (8117) - Some high-volume turboprop and turbojet engines are equipped with two-spool or split
compressors. When these engines are operated at high altitudes, the - CORRECT ANSWER A- low-
pressure rotor will increase in speed as the compressor load decreases in the lower density air.



11 (8118) - Turbine nozzle diaphragms located on the upstream side of each turbine wheel, are used in
the gas turbine engine to - CORRECT ANSWER C- increase the velocity of the heated gases flowing past
this point.



12 (8119) - Where is the highest gas pressure in a turbojet engine? - CORRECT ANSWER C- In the
entrance of the burner section.



13 (8120) - An exhaust cone placed aft of the turbine in a jet engine will cause the pressure in the first
part of the exhaust duct to - CORRECT ANSWER A- increase and the velocity to decrease.



14 (8121) - What is the function of the stator vane assembly at the discharge end of a typical axial-flow
compressor? - CORRECT ANSWER A- To straighten airflow to eliminate turbulence.



15 (8122) - The turbine section of a jet engine - CORRECT ANSWER C- drives the compressor section.



16 (8123) - When starting a turbine engine, - CORRECT ANSWER A- a hot start is indicated if the exhaust
gas temperature exceeds specified limits.



17 (8124) - In the dual axial-flow or twin spool compressor system, the first stage turbine drives the -
CORRECT ANSWER B- N(2) compressor.



18 (8125) - During inspection, turbine engine components exposed to high temperatures may only be
marked with such materials as allowed by the manufacturer. These materials generally include 1. layout
dye.2. commercial felt tip marker.3. wax or grease pencil.4. chalk.5. graphite lead pencil. - CORRECT
ANSWER A- 1, 2, and 4.



19 (8126) - When starting a turbine engine, a hung start is indicated if the engine - CORRECT ANSWER B-
fails to reach idle RPM.
