摘要： A propulsor fan and drive system having reduced noise emission is disclosed. The propulsor fan includes a blade fan having a plurality of blades. The blade fan is tensioned at the tips of the plurality of blades. By tensioning the tips of the blades, an angle of the blades is maintained during operation of the propulsor fan thereby reducing noise that may result from changes in the angle of the blades.

摘要： A turbine wheel may include an inner hub having a central axis, an outer ring concentric with the inner hub, and an intermediate ring concentrically disposed between the inner hub and the outer ring, and a plurality of turbine blades extending between the intermediate ring and the outer ring. The turbine blades may be oriented to be driven by a fluid stream flowing through the turbine wheel to rotate the turbine wheel in a first direction about the central axis. In addition, the turbine wheel may further include a plurality of compressor blades extending between the inner hub and the intermediate ring. Also, the compressor blades may be oriented to propel a fluid in a downstream direction when the turbine wheel is rotated in the first direction.

摘要： A bypass turbomachine is disclosed. The turbomachine includes a longitudinal axis having an upstream blower impeller and a downstream air-flow straightening assembly of a secondary annular passage delimited radially on the inside by a radially inner shroud and radially on the outside by a radially outer shroud, blades extending between the radially inner and outer shrouds and being attached at a first end portion to the radially inner shroud and at a second end portion to the radially outer shroud, the blades including a useful portion extending between the first and second end portions and defining a lower face and an upper face. For each blade, in a plane perpendicular to the longitudinal axis, each aerodynamically useful portion is bent into a C-shape in the circumferential direction.

摘要： A system includes a casing alignment system configured to align an inner wall with an outer wall of a multi-wall casing of a turbomachine having a rotor. The casing alignment system includes a first alignment positioner configured to bias a first lip of the inner wall in a direction of rotation of the rotor disposed within the multi-wall casing. The alignment positioner may include a spring, a fluid-driven alignment positioner, an electric-driven alignment positioner, or a combination thereof. The alignment positioner may be configured to bias the first lip within a first recess adjacent a first flanged coupling between first and second wall sections of the outer wall.

摘要： In a method for estimating flange displacement amount, effective three-dimensional coordinate data at a lower first position on a surface continuous with a lower flange surface of a first supported portion and at an upper first position coincident with the lower first position in the horizontal direction on a surface continuous with an upper flange surface are determined. The effective three-dimensional coordinate data at the respective positions are changed such that the effective three-dimensional coordinate data at the lower first position and the effective three-dimensional coordinate data at the upper first position are coincident with each other. In accordance with a difference between a position in a vertical direction indicated by the effective three-dimensional coordinate data at an upper target position on the upper flange surface after a coordinate change and a position in the vertical direction indicated by the effective three-dimensional coordinate data at a lower target position on the lower flange surface after a coordinate change, displacement amounts of the upper target position and the lower target position in the vertical direction when a state changes from an open state to a fastened state are obtained.

摘要： A turbine housing that includes: a body part including a scroll passage wall surface, an exhaust gas discharge path wall surface, and a wastegate passage wall surface provided inside the body part, the scroll passage wall surface forming a scroll passage having a scroll shape, the wastegate passage wall surface forming a wastegate passage connecting the scroll passage and the exhaust gas discharge path to each other while bypassing the turbine wheel; and an entrance flange part provided at an upstream end of the scroll passage in the body part, the entrance flange part including an exhaust gas inlet leading to the scroll passage. The wastegate passage has an entrance-side opening edge formed at the scroll passage wall surface and provided at a position where the entrance-side opening edge is visually recognizable at least partially from outside the turbine housing through the exhaust gas inlet.
