EASA Module 14 Practice Questions - EASA Part-66 Module 14 - Propulsion (B2) Exam - EASA Module 14 Practice Questions - EASA Part-66 Module 14

Question 1

In a turbojet engine, thrust is produced primarily in accordance with which physical principle?

Newton's third law: the reaction to the rearward acceleration of the gas stream Bernoulli's principle acting on the compressor blades only Boyle's law applied at constant temperature in the combustion chamber Charles's law as the exhaust gases expand at constant pressure

Correct Answer:

Newton's third law: the reaction to the rearward acceleration of the gas stream

Question 2

A high-bypass turbofan obtains the majority of its thrust from which source?

The core exhaust (hot stream) leaving the low-pressure turbine The afterburner augmentation in cruise The bypass (fan/cold) air stream accelerated by the fan The bleed air extracted for the air-conditioning packs

Correct Answer:

The bypass (fan/cold) air stream accelerated by the fan

Question 3

In a turboshaft engine, the energy of the gas stream is used primarily to:

Produce reactive jet thrust at the exhaust nozzle Drive a free (power) turbine that delivers shaft power to a rotor or load Drive only the engine's own compressor with no useful output Generate electrical power directly without any rotating turbine

Correct Answer:

Drive a free (power) turbine that delivers shaft power to a rotor or load

Question 4

The constructional difference between a turboprop and a turboshaft engine is mainly that the turboprop:

Uses a reduction gearbox to drive a propeller and may produce some residual jet thrust Has no compressor section Operates without a combustion chamber Produces all of its thrust from the exhaust nozzle like a turbojet

Correct Answer:

Uses a reduction gearbox to drive a propeller and may produce some residual jet thrust

Question 5

Which statement about net thrust versus gross thrust of a gas-turbine engine in forward flight is correct?

Net thrust is always greater than gross thrust Gross thrust equals net thrust minus the intake ram pressure rise Net thrust is independent of aircraft forward speed Net thrust equals gross thrust minus the momentum (ram) drag of the incoming air

Correct Answer:

Net thrust equals gross thrust minus the momentum (ram) drag of the incoming air
