    Abstract: A turbine exhaust diffuser (12) for a gas turbine engine having a turbine section, the exhaust diffuser (12) includes a flowpath (14) downstream of the turbine section. The flowpath (14) is defined at least in part by a turbine casing (16) having an inner casing (18) forming an ID flowpath boundary (20) and an outer casing (22) forming an OD flowpath boundary (24). A least one strut (26) is positioned within the flowpath (14) and spans between the inner casing (18) and the outer casing (22). The exhaust diffuser (12) includes an undulating portion (32) located along at least one of the inner casing (18) and the outer casing (22) along the exhaust diffuser (12). The undulating portion (32) includes at least a first point (34) upstream of the at least one strut (26) and a second point (36) approximate to a halfway span of the at least one strut (26). The undulating portion (32) includes radially and axially extending crests (42) and troughs (44).

    Abstract: A gas turbine engine component includes an outer diameter endwall, an inner diameter endwall spaced radially inward of the outer diameter endwall, and at least one body supported between the outer and inner endwalls for rotation about an axis. The body includes an outer diameter surface spaced from the outer diameter endwall by a first gap and an inner diameter surface spaced from the inner diameter endwall by a second gap. The outer and inner diameter surfaces and the outer and inner diameter endwalls are configured such that the first and second gaps remain generally constant in size as the body rotates about the axis.

    Abstract: Turbine component with an interior coating surface comprising multi- scale turbulation features, including first turbulators (46, 48) formed on a cooling surface (44), and smaller turbulators (52, 54, 58, 62) formed on the first turbulators. The first turbulators may be formed between larger turbulators (50). The first turbulators may be alternating ridges (46) and valleys (48). The smaller turbulators may be concave surface features such as dimples (62) and grooves (54), and/or convex surface features such as bumps (58) and smaller ridges (52). An arrangement with convex turbulators (52, 58) in the valleys (48) and concave turbulators (54, 62) on the ridges (46) increases the cooling surface area, reduces boundary layer separation, avoids coolant shadowing and stagnation, and reduces component mass.
