Abstract (en)
An aerofoil (10) for a turbocharger stator for a large diesel engine has a convex, upper wall (12) and a concave, lower wall (14) with a leading edge (16) and a trailing edge (18). A wiggle strip (22) extends the length of the aerofoil and is brazed to the walls to provide added strength. The inner surface of the wall (12) is reinforced by a plate (20) extending from the trailing edge to a point in the region of the maximum spacing between the walls (12, 14). The plate is a shaped reinforcement piece and gives added strength to the area of the wall (12) which is impacted by cleaning medium. It provides a localised reinforcement to the area which is prone to damage by cleaning. <IMAGE>
