NON-UNIFORM VARIABLE VANES |
摘要 |
Non-uniform variable stator vanes for a single stage of a gas turbine engine stage include non-uniform airfoils with a non-uniformity between airfoils of first and second portions of the stator vanes. The variable stator vanes may further include all outer buttons, from which the airfoils inwardly extend, in all of the variable stator vanes being equally sized and shaped and the same all inner buttons if used. The airfoils in the first and second portions may be counter--clockwise and clockwise biased respectively with respect to a nominal airfoil position. The airfoils in the first and second portions may be counter-clockwise and clockwise leaned respectively with respect to the nominal airfoil position. Outer ends of the airfoils in the first and second portions may be counter--clockwise and clockwise shifted respectively with respect to the nominal airfoil position. |
