An air cooled integrally bladed rotor with bore entry cooling holes for a small gas turbine engine cast using a ceramic core having an axial bore forming piece with a plurality of radial extending spokes that end in an annular ring to form cooling air supply passages for air cooled turbine blades. Bulbous chambers are formed in a circumferential cooling air supply channel formed below each blade, where cooling air holes are drilled from a tip of each blade and into the bulbous chambers. The radial spokes have an elliptical cross sectional shape with a major axis perpendicular to a rotational axis of the central bore of the IBR. A spacing of the inlet openings in the bore are minimized to reduce stress.

A layer system having a metallic substrate, in particular made of a >=9% by weight chromium steel, in particular with roughness of the substrate <=2 m and optionally an intervening chromium layer directly on the substrate, in particular made of Cr/CrN, an underlayer or middle layer of AlCr, and an outer layer, in particular outermost layer, of AlCrO, where the AlCr and AlCrO layers in particular are PVD coatings wherein a shark skin effect is achieved with a simple geometric arrangement, and can be used particularly for compressor blades.

A bearing support structure for a gas turbine engine located within an internal portion of the engine. The bearing support structure has a plurality of stators, a first section, a second section, a first bearing assembly, and a second bearing assembly. The first section depends forwardly from the plurality of stators relative to the longitudinal axis. The section second depends rearwardly from the plurality of stators relative to the longitudinal axis and is detachably mounted to the plurality of stators. The first bearing assembly is supported relative to the plurality of stators by the first section. The second bearing assembly is supported relative to the plurality of stators by the second section. The second section is detachably mounted to the plurality of stators.

A turbine housing for a turbocharger includes an inlet passage and an outlet passage connected to a turbine housing body. The outlet passage has a longitudinal axis and comprises a first section and a second section downstream of the first section. The first section includes a first inlet opening having a first cross-sectional area, a first outlet opening downstream of the first inlet opening, and a first length between the first inlet opening and the first outlet opening, wherein the first section has an opening angle between 0 and 10 relative to the longitudinal axis along the first length. The second section downstream of the first section includes a second inlet opening, a second outlet opening downstream of the second inlet opening, a second cross-sectional area at least 1.8 times greater than the first cross-sectional area, and a second length between the second inlet opening and the second outlet opening that is less than 50% of the first length.

A compressor rotor includes a first disk and a conical section connected to the first disk. The conical section includes at least one flow hole. A bore cavity is defined between the conical section and the first disk. The bore cavity is arranged in fluid communication with the at least one flow hole. An anti-vortex tube is disposed within the at least one flow hole of the conical section and includes at least one feature arranged in contact with a surface of the conical section to restrict movement of the anti-vortex tube out of engagement with the conical section.

A method and apparatus for minimizing engine weight for a turbine engine by utilizing one or more discrete protuberances disposed on an engine component wall. The wall can have a nominal thickness to decrease engine weight while the protuberances can provide increased discrete thicknesses for providing one or more cooling holes. The increased thickness at the protuberances provides for an increased thickness to provide sufficient length to increase cooling hole effectiveness.
