Abstract

A combustor wall (76) includes a panel (88), a boss (86), a wall aperture (90) and multiple cooling apertures (118A, 118B). The panel (88) extends axially along and circumferentially about an axial centerline (22). The panel (88) extends radially between a first panel surface (128) and a second panel surface (130). The first panel surface (128) forms a peripheral boundary of a combustion chamber (58). The boss (86) projects out from the second panel surface (130). The boss (86) extends circumferentially around and forms an outer peripheral boundary of the wall aperture (90). The wall aperture (90) extends along a wall aperture centerline (148) through the combustor wall (76) to the first panel surface (128). The cooling apertures (118A, 118B) are arranged circumferentially about the wall aperture (90). Each of the cooling apertures (118A, 118B) extends along a cooling aperture centerline (180, 192) through the panel (88) and/or the boss (86) to the wall aperture (90). The cooling aperture centerline (180) of a first of the cooling apertures (118A) is angularly offset from the wall aperture centerline (148) by a first acute angle (190).
