1
Q
Which aerofoil design can increase Mcrit ?
A
Thin aerofoil
Sweepback wings
(vortex generators)
2
Q
Is there a shockwave on lower surface of an aerofoil?
A
Yes when Mfs continues to increase above Mcrit
3
Q
How many shockwaves are there around an aerofoil?
A
Upper and lower surface and bow shockwaves
4
Q
What is the range of Mach number for transonic flight?
A
Mcrit - Mdet
5
Q
How does the pressure distribution over an aerofoil change when a normal shockwave formed on the aerofoil?
A
The change of pressure distribution will change suddenly
