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.

Abstract: A tool for removal of a bushing (such as a bushing of a variable stator vane assembly of a compressor) is provided. The tool includes a cylindrical housing, a lead screw, a threaded nut, and a pulling module with puller arms to engage the bushing. The housing defines a longitudinal axis along which the lead screw extends. The lead screw is rotatably secured within the cylindrical housing by a threaded nut engaged with the lead screw. The pulling module is removably attached to the threaded nut, such that the lead screw passes through the threaded nut before passing through the pulling module. The pulling module is provided with a pair of oppositely disposed puller arms, and each puller arm is provided with a hook portion having an engagement tab configured to engage a respective notch on the bushing. A method of removing the bushing using the tool is also disclosed.

IPC: F01D9/04
Abstract: A stator vane includes an airfoil having an airfoil shape. The airfoil shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in one of Table I, Table II, Table III, Table IV, Table V, Table VI, Table VII, or Table VIII. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values are joined smoothly with one another to form a complete airfoil shape.
