Abstract
A disclosed stator vane assembly includes a plurality of stator vane elements supported within a case about an axis. Each of the plurality of stator vane elements includes a platform having a recess on a first side and a tongue on a second side. The tongue overlaps a recess of an adjacent one of the plurality of stator vane elements with at least one of the recess and the tongue includes a crowned surface forming a seal.
Claims16
A compressor assembly comprising:
- a case disposed about an axis;
- and
- a stator vane supported within the case and including a platform with a first side including a recess and a second side including a tongue for overlapping a recess on a platform of an adjacent stator vane, wherein both the first side and the second side are disposed at an angle relative to the axis.
A stator vane stage comprising:
- a plurality of stator vanes supported within a case about an axis, wherein each of the plurality of stator vanes includes a platform having a recess on a first side and a tongue on a second side, wherein the tongue overlaps a recess of an adjacent one of the plurality of stator vanes, wherein at least one of the recess and the tongue includes a crowned surface forming a seal.
A stator vane comprising:
- a platform including a first side having a recess, a second side having a tongue, and first and second ends having hooks, wherein the tongue overlaps a recess on an adjacent stator vane;
- and an airfoil extending from the platform, wherein first and second sides are disposed at a non-normal angle relative to the first and second ends, including a crowned surface on one of the recess and the tongue for forming a seal at the interface between a recess and a tongue of adjacent stator vanes.
