CAA NZ Basic Turbine Knowledge (Aeroplane) Practice Questions - CAA NZ Basic Turbine Knowledge (Aeroplane) Exam (New Zealand) Exam - CAA NZ Basic Turbine Knowledge (Aeroplane) Practice Questions - CAA NZ Basic Turbine Knowledge (Aeroplane) Exam (New Zealand) Exam

Question 1

Which fundamental thermodynamic cycle describes the operational process of a continuous-flow gas turbine engine?

Brayton cycle Otto cycle Diesel cycle Carnot cycle

Correct Answer:

Brayton cycle

Question 2

What is the main operational advantage of a free-turbine turboprop engine compared to a single-shaft turboprop engine?

The propeller can turn independently of the gas generator spool, resulting in lower starter load The engine consumes significantly less fuel during high-altitude cruise The propeller is permanently locked to the high-pressure compressor shaft It eliminates the requirement for a reduction gearbox

Correct Answer:

The propeller can turn independently of the gas generator spool, resulting in lower starter load

Question 3

What is the primary function of the compressor section in a gas turbine engine?

To increase the pressure and density of air before it enters the combustion chamber To extract thermal energy from expanding combustion gases To atomize fuel and mix it with high-velocity air To expand exhaust gases to create forward jet thrust

Correct Answer:

To increase the pressure and density of air before it enters the combustion chamber

Question 4

What is the primary purpose of the diffuser section positioned downstream of the compressor?

To decrease air velocity and increase static pressure before combustion To increase air velocity and decrease static pressure before the turbine To mix fuel evenly with high-speed air prior to ignition To cool high-temperature air before it enters the turbine

Correct Answer:

To decrease air velocity and increase static pressure before combustion

Question 5

What is a typical pressure ratio achieved per stage by a centrifugal compressor?

4:1 to 5:1 1.1:1 to 1.2:1 15:1 to 20:1 30:1 to 40:1

Correct Answer:

4:1 to 5:1
