    摘要: Part-span shrouds for pitch controlled aircrafts are disclosed herein. An example apparatus includes a first portion extending from a first airfoil, the first portion including a first surface, the first surface being convex, a second portion extending from a second airfoil towards the first airfoil, the second portion including a second surface the first airfoil circumferentially adjacent to the second airfoil, the second surface being concave, and an interface formed by the first surface and the second surface, the interface reacting circumferential loads between the first airfoil and the second airfoil.

    摘要: Assembly comprising a body extending around a central axis, the body having an outer surface from which a plurality of blades extend, each of said blades having a blade root and a blade tip, defining an inner radial end and an outer radial end of the blade relative to the central axis, said blades having the same blade height measured radially relative to the central axis, characterized in that each of the blades is connected to the body by its blade root via a connection having a nonzero connection height, so that for the plurality of said blades, the connection height of two successive blades is different.

    摘要: A blade set of the present disclosure is exposed to a working fluid, which includes a blade main bodies which are disposed at intervals in a circumferential direction about an axis and each extending in a radial direction with respect to the axis wherein a tip end surface is formed on an outer circumferential side of each blade main body and the tip end surface of the blade main body includes a leading edge side region positioned on an upstream side in a flow direction of the working fluid along the axis and a trailing edge side region positioned on a downstream side in the flow direction, and a shroud which is provided on an outer circumferential side of the blade main bodies and covering either the leading edge side regions or the trailing edge side regions of the blade main bodies.
