What is the primary role of the compressor in a turbine engine?

• To cool the engine

• To compress incoming air and increase its pressure

• To ignite the fuel

• To reduce engine noise

Which section of the turbine engine is responsible for producing high-energy exhaust gases by burning the fuel-air mixture?

• Fan section

• Compressor section

• Combustion chamber

• Turbine section

What function does the fan section serve in a turbofan engine?

• It stores fuel for the engine

• It accelerates a large mass of air to increase thrust

• It filters out impurities from the air

• It cools the engine components

What is the main function of the turbine section in a turbine engine?

• To generate electricity

• To convert exhaust gas energy into mechanical energy to drive the compressor

• To store lubricating oil

• To provide a cooling effect

Which component of the turbine engine is responsible for directing exhaust gases to produce thrust?

• Compressor

• Turbine

• Combustion chamber

• Nozzle

How does the design of the annular combustion chamber benefit turbine engine performance?

• It reduces the overall weight of the engine

• It provides a uniform temperature distribution and efficient combustion

• It simplifies the engine's maintenance

• It increases the engine's noise level

What is a critical function of the guide vanes in the compressor section of a turbine engine?

• They provide thrust to the engine

• They direct airflow efficiently through the compressor stages

• They ignite the fuel-air mixture

• They store excess fuel

Why is it important for the turbine blades to be made of high-temperature resistant materials?

• To reduce the cost of the engine

• To ensure they maintain structural integrity under high-temperature exhaust gases

• To make them easier to manufacture

• To increase their weight

What is the term for the high-speed exhaust component that contributes to the thrust in a turbine engine?
