Turbine Engine Quiz 1

Which condition would be the least likely to be caused by failed or failing engine bearing?

• Excessive oil consumption

• High oil temperatures

• Low oil temperatures

At what point in an axial-flow turbojet engine will the highest gas pressures occur?

• At the turbine entrance

• Within the burner section

• At the compressor outlet

The fan rotational speed of a dual axial compressor forward fan engine is the same as the

• low-pressure compressor

• forward turbine wheel

• high-pressure compressor

The abbreviation "P" with subscript t7 used in turbine engine terminology means

• the total inlet pressure.

• pressure and temperature at station No.7.

  
  

• the total pressure at station No.7.

  
  

What turbine engine section provides for proper mixing of the fuel and air?

• Combustion section

• Compressor section

• Diffuser section

In a gas turbine engine, combustion occurs at a constant

• volume

• pressure

• density

Which statement is true regarding jet engines?

• At the lower engine speeds, thrust increases rapidly with small increases in RPM

• At the higher engine speeds, thrust increases rapidly with small increases in RPM

• The thrust delivered per pound of air consumed is less at high altitude than at low altitude

Where is the highest gas pressure in a turbojet engine?

• At the outlet of the tailpipe section

• At the entrance of the turbine section

• In the entrance of the burner section

What is the function of the stator vane assembly at the discharge end of a typical axial-flow compressor?

• To straighten airflow to eliminate turbulence

• To direct the flow of gases into the combustion chambers

• To increase air swirling motion into the combustion chambers

The turbine section of a jet engine

• increases air velocity to generate thrust forces.

  
  

• utilizes heat energy to expand and accelerate the incoming gas flow.

  
  

•  drives the compressor section.
