Abstract

A rotor blade (72) includes an airfoil (86), a root (90), a cooling air passage (122) and a cooling air deflector (94). The root (90) extends axially along an axis (24) between a first end (114) and a second end (116). The root (90) extends laterally between a first side (118A) and a second side (118B). The root (90) projects radially inward and away from the airfoil (86) to an inner end (112) of the root (90). The cooling air passage (122) includes a passage inlet (124) disposed at the inner end (112). The cooling air passage (122) projects radially into the rotor blade (72) from the passage inlet (124). The cooling air deflector (94) projects radially inward from the inner end (112) of the root (90) to an inner end (130) of the cooling air deflector (94). The cooling air deflector (94) is disposed at the second side (118B) and is spaced laterally from the first side (118A). The cooling air deflector (94) includes a cooling air aperture (150).
