Question 1

On a swept-wing turbine aeroplane, the speed at which airflow over the upper wing surface first reaches Mach 1.0 (M=1.0) locally while the aircraft itself is still subsonic is known as the:

Critical Mach number (Mcrit) Mach number Coffin corner speed Drag divergence Mach number

Correct Answer:

Critical Mach number (Mcrit)

Question 2

As airflow passes through a normal shock wave on the upper surface of a wing in transonic flight, the static pressure of the air:

Decreases and velocity increases Increases and velocity decreases to subsonic Remains constant while temperature falls Decreases while density falls

Correct Answer:

Increases and velocity decreases to subsonic

Question 3

A leading-edge slat improves the low-speed lift of a wing primarily by:

Increasing the wing camber only Reducing the wing area to lower stall speed Energising the boundary layer and delaying the stall to a higher angle of attack Increasing the chord line incidence relative to the fuselage

Correct Answer:

Energising the boundary layer and delaying the stall to a higher angle of attack

Question 4

On a large transport aeroplane, roll control at high speed is often provided by spoilers in addition to ailerons mainly because:

Spoilers create more lift than ailerons Ailerons cannot be powered hydraulically Spoilers reduce the aircraft's stall speed Outboard ailerons can cause wing twist (aileron reversal) at high dynamic pressure

Correct Answer:

Outboard ailerons can cause wing twist (aileron reversal) at high dynamic pressure

Question 5

In a 'fail-safe' airframe structural design philosophy, structural integrity after a single failure is assured because:

Multiple load paths exist so remaining structure carries the load until the failure is detected Every component is replaced at a fixed flight-hour life regardless of condition The component is designed never to crack within the aircraft's life Inspections are eliminated because the part cannot fail

Correct Answer:

Multiple load paths exist so remaining structure carries the load until the failure is detected
