Abstract

A self-cooled orifice structure, for example a dilution hole structure for a combustor of a gas turbine engine, includes a cold side panel spaced from a hot side panel, and a continuous inner wall extending between the hot and cold side panels and defining an orifice communicating through the hot and cold side panels. A plurality of end walls of the structure are in a cooling cavity that is defined in-part by the hot and cold side panels and the inner wall. Each end wall extends between and are engaged to the hot and cold side panels and are circumferentially spaced from the next adjacent end wall. A plurality of inlet apertures extend through the cold side panel, in fluid communication with the cavity, and proximate to a first side of the end walls. A plurality of outlet apertures extend through the hot side panel, in fluid communication with the cavity, and associated with an opposite second side of the end walls.
