Abstract
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 localized reinforcement to the area which is prone to damage by cleaning.
Claims11
A vane for a turbocharger stator, comprising:
- the vane being of generally hollow construction with a convex wall and a concave wall meeting at a leading edge and a trailing edge of the vane;
- said convex wall being thickened over a portion of an inner surface thereof by a reinforcing plate secured to said inner surface of said convex wall;
- said convex wall and said concave wall defining a region of maximum spacing between said convex and concave walls between said leading edge and said trailing edge, of the vane;
- and
- said reinforcing plate extending from said trailing edge to a point in said region of the maximum spacing between said convex and concave walls to serve as a reinforcement to an area of the vane prone to damage during cleaning by impacting cleaning material.
