    摘要: An improved heat transfer assembly includes a textured impingement surface and means for impinging cooling air directly upon the textured surface. A component includes a surface textured to increase convective heat transfer with minimal increase in resistance to conductive heat transfer through the component. The textured surface can comprise an array of closely spaced hemispherically shaped protuberances. A method is disclosed for texturing a surface with discrete laser welds.

    摘要: Assembly of the combustor dome in a gas turbine engine is facilitated by providing a self-fixturing configuration. The combustor dome assembly is made up of a dome plate having a plurality of swirler assemblies mounted therein. Each swirler assembly is provided with a locating pin that extends between the dome plate and the swirler assembly for positioning the swirler assembly with respect to the dome plate without the use of fixturing tools. Preferably, the swirler assembly includes a swirl cup and an outlet sleeve mounted in the dome plate. The locating pin is pressed into a hole formed in the swirl cup. One end of the pin is received in a slot formed in the dome plate, and the other end of the pin is received in a slot formed in the outlet sleeve. Thus, the locating pin sets the circumferential orientation of the swirler assembly in relation to the dome plate. A shoulder on the swirl cup sets the cup axially with respect to the dome plate, and a shoulder on the outlet sleeve sets the sleeve axially with respect to the swirl cup.

    摘要: A double annular combustor having concentrically disposed inner and outer annular combustors is provided with inner and outer dome plates. Each dome plate has an inner portion and an outer portion. A cowl structure having an inner portion, an outer portion and a middle portion is also provided. The cowl outer portion is connected to the outer dome plate outer portion, the cowl inner portion is connected to the inner dome plate inner portion, and the cowl middle portion is connected to the outer dome plate inner portion and the inner dome plate outer portion. at an outer end, an inner end, and a middle portion. Additionally, the inner and outer annular combustors may lie in distinct radial planes, whereby the dome plate of the downstream annular combustor includes a section extending upstream to the cowl middle portion.
