SAR-66 Module 15 Practice Questions - CAAS SAR-66 AML Module 15 - Gas Turbine Engine Exam - SAR-66 Module 15 Practice Questions - CAAS SAR-66 AML Module 15

Question 1

Which thermodynamic cycle describes the constant-pressure continuous combustion process in a gas turbine engine?

Brayton cycle Otto cycle Diesel cycle Carnot cycle

Correct Answer:

Brayton cycle

Question 2

An aircraft turbojet engine ingests an airflow rate of 50 kg/s at a flight speed of 200 m/s. If the exhaust jet velocity is 500 m/s, what is the net unchoked thrust Fn generated (assuming fuel mass flow is negligible)?

15000 N 25000 N 10000 N 35000 N

Correct Answer:

15000 N

Question 3

How is Thrust Specific Fuel Consumption (TSFC) defined for a gas turbine engine?

The fuel mass flow rate per hour divided by the net thrust generated (kg / (N * h)) The total fuel consumed during a flight divided by distance traveled The ratio of turbine inlet temperature to compressor pressure ratio The electrical power output generated by the APU generator per liter of fuel

Correct Answer:

The fuel mass flow rate per hour divided by the net thrust generated (kg / (N * h))

Question 4

What is the primary function of stator vanes in an axial flow compressor stage?

To convert kinetic energy imparted by the rotor into static pressure and direct airflow at the correct angle to the next rotor stage To accelerate airflow to supersonic speeds before combustion To ignite the compressed air-fuel mixture To prevent turbine blade overspeed during acceleration

Correct Answer:

To convert kinetic energy imparted by the rotor into static pressure and direct airflow at the correct angle to the next rotor stage

Question 5

What causes an axial compressor aerodynamic stall?

The local angle of attack of airflow over compressor rotor blades exceeds the critical stall angle Fuel pressure delivered by the HMU exceeds combustion chamber pressure Turbine inlet temperature drops below 200 °C The compressor pressure ratio falls to zero

Correct Answer:

The local angle of attack of airflow over compressor rotor blades exceeds the critical stall angle
