CAAS SAR-66 Module 14 Propulsion Practice Questions - CAAS SAR-66 Module 14 Propulsion (Category B2 Avionics) Exam - CAAS SAR-66 Module 14 Propulsion Practice Questions - CAAS SAR-66 Module 14 Propulsion (Category B2 Avionics) Exam

Question 1

In a gas turbine engine operating on the ideal Brayton cycle, which thermodynamic process occurs inside the combustion chamber?

Isentropic compression Constant pressure heat addition Isothermal expansion Constant volume combustion

Correct Answer:

Constant pressure heat addition

Question 2

An engine exhaust nozzle has a total pressure (Pt7) of 45 psia and the engine inlet total pressure (Pt2) is 15 psia. What is the indicated Engine Pressure Ratio (EPR)?

0.33 3.00 30.0 60.0

Correct Answer:

3.00

Question 3

A turbofan engine ingests air at a mass flow rate of 120 kg/s. The aircraft is flying at a true airspeed of 150 m/s, and the exhaust gas exit velocity is 400 m/s. Assuming a fully expanded convergent nozzle (Pj = Pa), calculate the net thrust (Fn).

18,000 N 30,000 N 48,000 N 66,000 N

Correct Answer:

30,000 N

Question 4

What happens to the net thrust produced by a gas turbine engine as aircraft flight altitude increases at a constant true airspeed and engine RPM?

Net thrust increases due to lower ambient temperature. Net thrust decreases due to the primary effect of reduced ambient air density. Net thrust remains constant because ram pressure recovery compensates for altitude loss. Net thrust increases continuously up to the tropopause.

Correct Answer:

Net thrust decreases due to the primary effect of reduced ambient air density.

Question 5

The propulsive efficiency (eta_p) of a jet engine is expressed by which of the following mathematical relations, where Va is aircraft speed and Vj is jet velocity?

eta_p = (Vj - Va) / (Vj + Va) eta_p = 2 * Va / (Vj + Va) eta_p = Va^2 / Vj^2 eta_p = (Vj + Va) / (2 * Va)

Correct Answer:

eta_p = 2 * Va / (Vj + Va)
