Abstract

A turbine engine rotor blade (76) is provided that has an airfoil (78) that includes a side wall (98) with exterior and interior wall surfaces. The airfoil (78) includes a first wall channel (104) that is defined by a base surface (110) that is a portion of the side wall interior surface and first and second interior wall surfaces (112, 114). A first interface surface (116) extends between the base surface (110) and the first interior wall surface (112). A second interface surface (118) extends between the base surface (110) and the second interior wall surface (114). A third interface surface (120) extends between the first interior wall surface (112) and the second interior wall surface (114). The base surface (110) includes base surface first and second segments (110A, 110B), and a peak interface surface (122) extending between the base surface first and second segments (110A, 110B). The first interface surface (116) is disposed closer to the side wall exterior surface (92) than both the second interface surface (118) and the peak interface surface (122).
