Abstract:
A locking member for a flow directing assembly and a shield for use in processing an airfoil of the flow directing assembly which is removable thereafter before operative use of the flow directing assembly, the flow directing assembly having a leading edge and a trailing edge, having an airfoil suction surface and an airfoil pressure surface, and having openings for passing cooling air from the flow directing assembly which include cooling air holes, the shield extending spanwisely and chordwisely about a portion of at least one of said airfoil surfaces, over at least a pair of the cooling air holes, over the airfoil surface between the pair of cooling air holes and chordwisely beyond the pair of cooling air holes toward the leading edge and the trailing edge, the locking member having an installed condition for blocking movement of the shield during processing, the locking member comprising a projection which is adapted to extend chordwisely between the assembly and the shield and which adapts the locking member to engage an opening for cooling air in the flow directing assembly and to block movement of the shield with respect to the flow directing assembly in the installed condition.
