Blade of a turbo machine

Abstract

The invention relates to a blade for a turbo machine with a blade; the outer surface of the blade in contact with fluid is formed of an elastic cover which surrounds a supporting structure; a flowable inflating medium is located between the elastic cover and the supporting structure; measures are taken in order to facilitate an overflowing of the inflating medium from the one side of the blade to the other side.
