Combustor liner

A combustor liner (20) includes a wall (20a) having an outboard surface (40) and an opposite inboard surface (42). A plurality of first holes (44) are inclined through the wall in a multihole pattern to channel cooling fluid (16) therethrough to form a cooling film layer (16b) along the inboard surf...

Zusammenfassung:	A combustor liner (20) includes a wall (20a) having an outboard surface (40) and an opposite inboard surface (42). A plurality of first holes (44) are inclined through the wall in a multihole pattern to channel cooling fluid (16) therethrough to form a cooling film layer (16b) along the inboard surface. A second hole (46) extends perpendicularly through the wall within the multihole pattern to form a shadow (48) along the inboard surface devoid of the first holes. A transition hole (50) extends through the wall in the shadow at a greater inclination than the first holes for cooling the wall at the shadow.
