As mentioned, they have the ability to feather the blades, apply
brakes and/or locking mechanisms and also the ability to rotate the
entire thing to a position which either stops the blades or puts a
different force on them.
However, that's not always successful. A direct hit with a tornado (of
any size) will likely do significant damage to the blades and/or hubs.
After a hit, they have to be hand inspected before being returned to
service. This requires a visual inspection that literally involves
rapelling down each blade (they rotate them into place) looking for
cracks. Depending on the damage, they can be fixed with a fiberglass
repair kit.
