A: the mean speed increases and the friction drag decreases.
B: the boundary layer gets thinner and the speed increases.
C: the mean speed and friction drag increases.
D: the boundary layer gets thicker and the speed decreases.
A: first appearance of a shock wave at the upper side of the wing.
B: attachment of the shock wave on the trailing edge of the wing.
C: separation of the boundary layer at the shock waves.
