Claims17
A vane for a gas turbine engine comprising:
- a radially inner platform,
- a radially outer platform,
- at least two airfoils extending between the radially inner platform and the radially outer platform, and
- at least two anti-rotation tabs extending axially from a leading edge of the radially outer platform, wherein a vane hook is spaced radially outward from the at least two anti-rotation tabs for engaging a recess formed in an engine static structure.
1 more element
A gas turbine engine comprising:
- an engine static structure including a plurality anti-rotation protrusions;
- and
- at least one vane including at least two anti-rotation tabs along a leading edge of a radially outer platform of the at least one vane, at least one of the at least two anti-rotation tabs engages one of the plurality anti-rotation protrusions and a vane hook spaced radially outward from the pair of anti-rotation tabs for engaging a recess formed in the engine static structure.
A method of assembling a gas turbine engine comprising:
- locating at least one vane adjacent an engine static structure, wherein the at least one vane includes a primary anti-rotation tab and a secondary anti-rotation tab along a leading edge of a radially outer platform of the at least one vane and a vane hook spaced radially outward from the primary anti-rotation tab and the secondary anti-rotation tab for engaging a recess formed in the engine static structure;
- and
- engaging the primary anti-rotation tab with at least one anti-rotation protrusion on the engine static structure.
