A shock wave is a sudden discontinuity in air temperature and pressure, in which
there is a considerable increase in density, pressure and temperature that
causes the boundary layer to separate into a shockstall. The shock wave acts as
if you ...

In the shock wave there is a considerable increase in density, pressure and
temperature which causes the boundary layer to separate into a shockstall. The
energy required for this comes from forward speed, so it is the equivalent of a
drag ...

He thought that doing a stall turn at that particular point was asking for a
shockstall, and he was not at all surprised that we had had one. In his opinion the
schedule should be changed andtheaerobatic put somewhere else. All well

Donaldson, Wilson, Waterton and other English pilots with plenty of shockstall
experience say the effect is that the air has turned into lead shot, the aircraft
shakes violently, there is often a roaring sound. ' The fact of the matter is that, at

At about Mach 0.65 a phenomenon, sometimes referred to as shockstall or
shockdrag, starts to occur. At this velocity, drag (inefficiency) will increase sharply
resulting in 300% to 400% increase in drag at around Mach 0.80. The term
shockstall ...
