摘要： A radial turbine impeller includes a hub having a substantially conical shape and multiple turbine blades provided on an outer peripheral surface of the hub at intervals in a rotational direction. In a meridian cross section, a hub line formed by the outer peripheral surface of the hub has a diameter that monotonically decreases from an upstream end on a radially outer side to a downstream end on a radially inner side, and includes a convex part that is convex toward a radially outer side.

摘要： The rotor comprises a plurality of rotor segments arranged axially adjacent to one another. A tie rod extends through the rotor segments. Opposed first and second locking members arranged at the axial ends of the tie rod lock the rotor segments to one another and to the tie rod. At least one intermediate support member is arranged in an intermediate position between the two axial ends of the tie rod and between the tie rod and one of the rotor segments.

摘要： A method for manufacturing a component of a rotary machine, the component extends in an axial direction and a radial direction vertical thereto, and has an inner channel, extending from a first end in a center of the component to a second end at a radial limiting surface of the component and which is partially closed. A blank includes the center of the component and is limited by an outer surface in the radial direction. The maximum dimension of the outer surface in the radial direction is smaller than the dimension of the limiting surface in the radial direction. A first subtractive process step is performed such that a part of the channel is manufactured by a machining process, with the part extending from the first end of the channel to the outer surface of the blank. Afterwards the channel is finished by a build-up process on the blank.

摘要： An assembly is provided for a turbine engine. This assembly includes a static structure and an impeller rotor housed within the static structure. The impeller rotor includes a vane structure and a shroud. The vane structure includes a first sidewall, a second sidewall and a plurality of vanes arranged circumferentially about a rotational axis. The vanes include a first vane. The first vane includes a first portion, a second portion and a third portion. The first portion is axially between the first sidewall and the second sidewall. The second portion is radially between the first sidewall and the shroud. The third portion is radially between the second sidewall and the shroud. The shroud circumscribes the vane structure. A gap is formed by and extends between the shroud and the static structure. A dimension of the gap changes as the gap extends along the shroud.
