Rotor blade having passive bleed path

摘要

A rotor blade (14) includes a bleed path (30) opening to a suction surface (28) eg. via inlet (32), extending through the blade (14), eg. via conduit (34), and exiting, eg. via outlet (36), to at least one of the suction surface (28) or a trailing surface (24). Working fluid flows through the bleed path (30) under centrifugal pumping forces when the blade rotates to passively bleed working fluid from the suction surface (28).
