COOLING PASSAGE WITH SURFACE FEATURES

摘要

A gas turbine engine component (61) includes at least one cooling passage (76). The at least one cooling passage (76) includes a first wall (86) and a second wall (87) bounding the at least one cooling passage (76), the first wall (86) having a plurality of first surface features (88) and the second wall (87) having a plurality of second surface features (89). The plurality of first surface features (88) and the plurality of second surface features (89) are arranged such that a width of the cooling passage (76) varies along a length of the cooling passage (76) defined by the plurality of first surface features (88) and the plurality of second surface features (89). The plurality of first surface features (88) has a first profile, and the plurality of second surface features (89) has a second, different profile.
