Module 15 Gas Turbine Engine Practice Questions - Aircraft Maintenance Licence (AML) Category B Module 15 Gas Turbine Engine Exam - Module 15 Gas Turbine Engine Practice Questions - Aircraft Maintenance Licence (AML) Category B Module 15 Gas Turbine Engine Exam

Question 1

Which of the following correctly describes the thermodynamic stages of the Brayton cycle in a gas turbine engine?

Constant volume combustion followed by constant temperature expansion Adiabatic compression, isobaric combustion, adiabatic expansion, isobaric heat rejection Isochoric compression, isothermal expansion, isobaric combustion, adiabatic exhaust Isothermal compression, isobaric combustion, isothermal expansion, isochoric exhaust

Correct Answer:

Adiabatic compression, isobaric combustion, adiabatic expansion, isobaric heat rejection

Question 2

In gas turbine engine performance, what is the mathematical relationship between net thrust (Fn) and gross thrust (Fg)?

Net thrust is equal to gross thrust plus the momentum drag of the fuel Net thrust is equal to gross thrust minus ram drag Net thrust is gross thrust multiplied by the compressor pressure ratio Net thrust is gross thrust divided by the exhaust gas velocity ratio

Correct Answer:

Net thrust is equal to gross thrust minus ram drag

Question 3

Which of the following design modifications will directly increase the thermal efficiency of a gas turbine engine?

Decreasing the turbine inlet temperature to reduce blade thermal stress Increasing the compressor pressure ratio and increasing the turbine inlet temperature Decreasing the compressor stage efficiency to increase compressor outlet temperature Reducing the bypass ratio of the engine to increase jet velocity

Correct Answer:

Increasing the compressor pressure ratio and increasing the turbine inlet temperature

Question 4

How does the speed of sound vary with altitude within the troposphere, and what is its effect on the engine's Mach number?

The speed of sound increases with altitude, increasing the engine Mach number for a constant flight speed The speed of sound decreases with altitude, increasing the engine Mach number for a constant flight speed The speed of sound remains constant, having no effect on the engine Mach number The speed of sound decreases with altitude, decreasing the engine Mach number for a constant flight speed

Correct Answer:

The speed of sound decreases with altitude, increasing the engine Mach number for a constant flight speed

Question 5

According to Bernoulli's theorem, what happens to subsonic air as it flows through a divergent duct?

Velocity increases, static pressure decreases, and temperature decreases Velocity decreases, static pressure increases, and temperature increases Velocity increases, static pressure increases, and temperature remains constant Velocity remains constant, while static pressure and temperature decrease

Correct Answer:

Velocity decreases, static pressure increases, and temperature increases
