Sample Questions

Question 1
What is the definition of the critical Mach number (M_crit) for an airfoil?
The free-stream Mach number at which the local air velocity at some point on the airfoil first reaches the speed of sound.
The Mach number at which the drag coefficient begins to rise rapidly due to shockwave formation.
The speed at which the boundary layer separates completely from the upper wing surface.
The Mach number at which the aircraft enters a state of uncontrollable nose-down pitch (mach tuck).
Question 2
Which of the following occurs as a primary result of the formation of a normal shockwave on the upper surface of a wing?
The local airflow behind the shockwave becomes supersonic and static pressure drops.
The local airflow behind the shockwave becomes subsonic, static pressure increases, and density increases.
The boundary layer becomes thinner and re-attaches to the wing surface.
The total pressure behind the shockwave increases significantly due to compression.
Question 3
What is the primary reason for incorporating wing sweepback on high-speed jet transport aircraft?
To increase the lift coefficient at low speeds and improve short-field takeoff performance.
To eliminate spanwise flow and prevent wing tip stall at high angles of attack.
To delay the onset of compressibility effects and increase the critical Mach number.
To reduce structural weight by allowing for a narrower wing root spar.
Question 4
What aerodynamic phenomenon is primarily responsible for the rapid increase in drag at Mach numbers above the critical Mach number?
Induced drag due to high lift coefficients.
Skin friction drag due to turbulent boundary layers.
Interference drag between the fuselage and the wing root.
Wave drag caused by the energy loss across shockwaves.
Question 5
In high-speed flight, what does the term 'Mach Tuck' refer to?
An automatic nose-down pitching moment caused by the rearward movement of the center of pressure as shockwaves form.
A sudden nose-up pitch caused by the wing tips stalling first on a swept-wing aircraft.
The loss of elevator effectiveness due to the shockwave attaching to the trailing edge.
A lateral oscillation (yaw/roll coupling) experienced when flying near the maximum operating Mach number.
