Turbine Engine Diagram and Parameters

Refer to Figure 1. Fill in the blank: The section labeled 'Air Inlet / Compressor' is responsible for increasing the ______ of the incoming air.

• pressure

• temperature

• velocity

• volume

Refer to Figure 1. Fill in the blank: The 'Combustion' section is where the air-fuel mixture is ______.

• ignited

• cooled

• compressed

• exhausted

Refer to Figure 1. Fill in the blank: The 'Turbine' section extracts energy from the ______ gases.

• exhaust gas from combustion chamber

• inert gas from bleed air

• compressed air from first stage baffle

• liquid sprayed on the 1st stage turbine

Fill in the blank: The 'Exhaust' section is where the gases are expelled at high ______.

• velocity

• Medium temperature

• High ratios

• volume

Which section of the turbine engine is responsible for compressing the air?

• Compressor

• Turbine

• Combustor

• Nozzle

State the purpose of the diffuser in a turbine engine.

• To increase the velocity of the airflow entering the combustion chamber.

• To decrease the velocity of the airflow and increase its pressure before entering the combustion chamber.

• To cool down the airflow before it enters the combustion chamber.

• To filter out impurities from the airflow before it enters the combustion chamber.

State the purpose of the combustion chamber in a turbine engine.

• To compress air before it enters the turbine

• To ignite the fuel-air mixture and produce high-pressure, high-velocity gas

• To cool the engine components

• To reduce noise produced by the engine

The pressure drops slightly or remains constant in the combustion section of a turbine engine because:

• the combustion process consumes pressure.

• the design of the engine maintains pressure.

• the pressure is regulated by external systems.

• the combustion section is sealed tightly.

The two basic sections of a turbine engine are:

• Compressor and Turbine

• Intake and Exhaust

• Combustion Chamber and Nozzle

• Fuel Tank and Engine Block

What are the two basic types of compressors that are used in aircraft turbine engines?

• Centrifugal and Axial

• Reciprocating and Rotary

• Screw and Scroll

• Piston and Diaphragm
