Abstract: A method of securing two components under this disclosure could be said to include receiving an input including a commanded pressure for achieving a pre-stretch on a shaft housed within a fixture. The shaft is coupled to a first component and extending through a second component. In response to receiving the input, causing hydraulic fluid to be provided to the fixture at a pressure based on the commanded pressure, to initiate the pre-stretch on the shaft. A measured stretch of the shaft is received from a sensor. Determining if the measured stretch is within a range of acceptable stretch; and based on a determination that the measured stretch is within the range of acceptable stretch, causing an indication of acceptability. The indication of acceptability being an instruction to tighten a nut to secure the shaft to the second component. A system and a controller are also disclosed.

Abstract: A hybrid shroud impeller including a hub having a first and a second axial end; the hub including an outer surface formed radially opposite a hub bore; a full blade extending radially from the outer surface; a splitter blade extending radially from the outer surface adjacent to the full blade; a bleed feature formed in a casing; a partial shroud integrally formed with a portion of the full blade and the splitter blade opposite the outer surface of the hub; a flow path formed between the outer surface of the hub, a shroud inner surface of the partial shroud and a blade surface of each of the full blade and the splitter blade; and the flow path extending from an inlet proximate the first axial end and an outlet proximate the second axial end; the partial shroud extends from the inlet to the bleed feature.

Abstract: An apparatus is provided for a gas turbine engine. This engine apparatus includes a shroud, and the shroud includes a wall and a bleed passage. The wall includes an interior surface and an exterior surface. The wall extends circumferentially about an axis. The wall extends depthwise between the interior surface and the exterior surface. The interior surface forms a peripheral boundary of a flowpath that extends along the shroud. The bleed passage includes an inlet orifice and an outlet orifice. The bleed passage extends through the shroud between the inlet orifice and the outlet orifice. The inlet orifice is disposed in the interior surface and fluidly couples the flowpath to the bleed passage. At least a downstream section of the bleed passage circumferentially tapers as the downstream section of the bleed passage extends within the wall towards the outlet orifice.

Abstract: An air conditioning unit is provided including a base pan having at least one hole surrounded by a first embossment including a first inclined sidewall and a first top wall. A mounting plate is positioned adjacent a portion of the base pan. The mounting plate has at least one opening surrounded by a second embossment including a second inclined sidewall and a second top wall. The at least one opening is generally aligned with the at least one hole. The second embossment overlays the first embossment such that a gap exists between the second inclined sidewall and the first inclined sidewall.

Abstract: A compressor includes a shell, a compression mechanism, a motor, a base member, and a mounting foot. The compression mechanism is disposed within the shell and the motor is drivingly engaged with the compression mechanism. The base member is coupled to the shell and a mounting foot is fixed to the base member. The mounting foot includes a mounting aperture extending therethrough and a slot intersecting the aperture that attenuates vibrations within an operating frequency range of the compressor.
