Q1. In a high bypass engine with a ‘pitot’ intake, with the engine running and the brakes on, what will $P_1$ be in relation to $P_0$?
Correct answer is – Less.
Q2. A pitot intake forms a duct ……… the fan to ensure that the airflow to and achieves a
Correct answer is – divergent before slows down subsonic pressure rise
Q3. What effect will severe icing in the intake have on a high bypass engine?
Correct answer is – The axial velocity of the air will decrease with an increase in the angle that the resultant airflow forms with the compressor blades chord line and a possible stall.
Q4. Which of the following would be classed as prudent when carrying out Engine Ground Runs?
Correct answer is – Fit debris guards when running.
Q5. With an ‘S’ type intake, if the pilot selects max rpm while standing still, there is a strong possibility that:
Correct answer is – the angle which the relative airflow forms with the compressor blades will become too large, which will cause the engine to stall and surge.
Q6. The purpose of an air inlet is to provide a relatively supply of air to the face of the compressor.
Correct answer is – turbulent free face low pressure
Q7. In a pitot intake the term ‘Ram Pressure Recovery’ refers to the time when:
Correct answer is – intake pressure has been re-established to ambient pressure.
