Compressor Blade With Flexible Tip Elements And Process Therefor
Abstract: A compressor blade (22) and process for inhibiting rub encounters between a blade tip (26) of the blade (22) and an interior surface (42) of a case (24) that surrounds the rotating hardware within a compressor section (20) of a turbomachine. The compressor blade (22) includes a cap (28) that defines the blade tip (26) at a radially outermost end of the blade (22), and a plurality of flexible elements (30) extending from a surface (26) of the cap (28) that defines the blade tip (26). The flexible elements (30) extend from the surface (26) in a span-wise direction of the blade (22), and are operable to become rigid due to centrifugal stiffening at compressor operating speeds and, optionally, cut a groove (44) the interior surface (42) of the case (24).
