Abstract
A turbine engine is provided. The turbine engine includes a plurality of first stator vanes, a plurality of second stator vanes, and a pitch adjustment system coupled to the first stator vanes and the second stator vanes. The pitch adjustment system includes a pivot shaft, a first linkage, and a second linkage. The pivot shaft has a first side and a second side opposite the first side. The first linkage is coupled to the first stator vanes on the first side of the pivot shaft. The second linkage coupled to the second stator vanes on the second side of the pivot shaft.
Claims20
A turbine engine comprising:
- a plurality of first stator vanes;
- a plurality of second stator vanes;
- and
- a pitch adjustment system coupled to said first stator vanes and said second stator vanes, said pitch adjustment system comprising a pivot shaft, a first linkage, and a second linkage, wherein said pivot shaft has a first side and a second side opposite said first side, said first linkage coupled to said first stator vanes on said first side of said pivot shaft, said second linkage coupled to said second stator vanes on said second side of said pivot shaft.
A pitch adjustment system for a turbine engine having a plurality of first stator vanes and a plurality of second stator vanes, said pitch adjustment system comprising:
- a pivot shaft having a first side and a second side opposite said first side;
- a first linkage coupled to said pivot shaft for coupling said first linkage to the first stator vanes on said first side of said pivot shaft;
- and
- a second linkage coupled to said pivot shaft for coupling said second linkage to the second stator vanes on said second side of said pivot shaft.
A method for setting a pitch adjustment system of a turbine engine, said method comprising:
- decoupling a foot of a linkage from a stator vane ring at a first datum feature of the stator vane ring;
- and
- recoupling the foot to the stator vane ring at a second datum feature of the stator vane ring, wherein the second datum feature is circumferentially spaced apart from the first datum feature.
