<p>With a turbo machine comprises a trunnion portion and an airfoil portion, the airfoil portion is defined by a leading edge, a trailing edge, and a pair of side edges. One or more of the side edges comprises a fin which extends from proximate to the trunnion portion toward the trailing edge of the airfoil portion. The fin tapers in thickness from the trunnion portion to the trailing edge portion. The fin may extend above and/or below the top and bottom surfaces of the airfoil. The fin may be formed on a portion of one or both of the side edges.</p> |
