    Abstract: ANGLED TRIPPED AIRFOIL PEANUT CAVITY A turbine airfoil comprises a wall portion, a cooling channel, an impingement rib, impingement rib nozzles, turbulators and leading edge cooling holes. The wall portion comprises a leading edge, a trailing edge, an outer diameter end, and an inner diameter end. The cooling channel receives cooling air and extends through an interior of the wall portion between the inner diameter end and the outer diameter end. The impingement rib is positioned within the wall portion forward of the cooling channel and between the outer diameter end and the inner diameter end to define a peanut cavity. The impingement rib nozzles extend through the impingement rib for receiving cooling air from the cooling channel. The turbulators are positioned within the peanut cavity to locally influence the flow of the cooling air. The leading edge cooling holes discharge the cooling air from the peanut cavity to an exterior of the wall portion.

    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.

    Abstract translation: 自冷却孔口结构（例如用于燃气涡轮发动机的燃烧器的稀释孔结构）包括与热侧面板间隔开的冷侧面板以及在热侧面板和冷侧面板之间延伸的连续内壁， 小孔通过冷热侧板连通。 该结构的多个端壁处于由冷热侧板和内壁部分地限定的冷却腔中。 每个端壁在热侧板和冷侧板之间延伸并与其接合，并与下一个相邻端壁周向间隔开。 多个入口孔延伸穿过冷侧板，与腔体流体连通并靠近端壁的第一侧。 多个出口孔延伸穿过热侧板，与腔体流体连通并且与端壁的相对的第二侧相关联。
