Well Aerodynamicists, is it really fluttering after the anhederal?
Peter Heath -
It looks like he had landing flap deployed then went to negative. In
the Schleicher gliders the landing flap transfers the lift to the
inner part of the wing and the tips then hang down or at higher
speeds could even lift downwards, hence the anhedral.
Sure looks like flutter to me, initiated by the impulse of moving the
lift outboard suddenly. This probably isn't a test condition that the
designer envisaged.
Fortunately the flutter was damped and ceased after a few oscillations.
