Aggregate vane assembly

摘要

An aggregate vane assembly is disclosed herein. The aggregate vane assembly includes a core vane assembly encircling a central longitudinal axis. The core vane assembly has a plurality of core vanes each extending radially between an inner hub and an outer band. The core vane assembly extends along the central longitudinal axis between a first forward end and a first aft end. The aggregate vane assembly also includes a bypass vane assembly disposed on a radially opposite side of the outer band relative to the plurality of core vanes. The bypass vane assembly includes at least one bypass vane extending radially outward from a platform. The bypass vane assembly extends along the central longitudinal axis between a second forward end and a second aft end. The aggregate vane assembly also includes at least one boss fixed with the outer band and operable to engage the bypass vane assembly proximate to the second forward end.

1. An aggregate vane assembly comprising:
a core vane assembly encircling a central longitudinal axis and having a plurality of core vanes each extending radially between an inner hub and an outer band wherein said core vane assembly extends along said central longitudinal axis between a first forward end and a first aft end; a bypass vane assembly disposed on a radially opposite side of said outer band relative to said plurality of core vanes, said bypass vane assembly including at least one bypass vane extending radially outward from a platform and said bypass vane assembly extending along said central longitudinal axis between a second forward end and a second aft end, and said bypass vane assembly including a lip extending from the platform; a ring formed of a plurality of ring segments; and a plurality of bosses fixed with said outer band and operable to engage said bypass vane assembly proximate to said second forward end wherein said plurality of bosses includes a first set of bosses and a second set of bosses; wherein said ring segments are secured to said first set of bosses; wherein engagement between said lip and said first set of bosses limits movement of the bypass vane assembly about the central longitudinal axis; and wherein engagement between said lip and said second set of bosses limits movement of the bypass vane assembly along the central longitudinal axis.
