Turbines 2 Quizz (1)

Two types of turbine compressors are

• Long and short

• Axial and centrifugal

• Pinion and planatary

• Clockwise and counterclockwise

The Brayton cycle used in most turbine engines is described as a constant_______ system

• Volume

• Pressure

• Velocity

• Sea Level

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

• In the exhaust duct

One function of the nozzle diaphragm in a turbine engine is to?

• Decrease the velocity of exhaust gases.

• Center the fuel spray in the combustion chamber

• 
  Direct the flow of gases to strike the turbine blades at a desired angle.

• Increase the volume of the burning fuel air mixture

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

• Compressor section.

• Diffuser section.

• The fuel control unit (FCU)

• Combustion section.

Which component on a turbine engine is responsible for supplying the engine with the correct volume of fuel based on engine load.

• Governor

• Fuel pump

• Fuel Control Unit (FCU)

• Fuel manifold

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.

• Is on the cold side of the engine

The two working parts of a turbine engine are usually referred to as the

• Single and twin spool sections

• Ignition and compression sections

• Clockwise and counter clockwise sections

• Hot and cold sections

In a turbo shaft engine, the output of the shaft is used to drive

• A propeller

• A helicopter rotor system

• A generator, compressor or other rotary mechanical device.

• All of the above

When starting a turbine engine,

• a hot start is indicated if the exhaust gas temperature exceeds specified limits.

• an excessively lean mixture is likely to cause a hot start

• release the starter switch as soon as indication of light-off occurs

• Always use a GPU ( Ground Power Unit ) to assist in starting
