<p>ACTUATING LEVER FOR VARIABLE STATOR VANES According to the present invention, there is provided an actuating lever for effecting concurrent vanes rotation in tandem rows of variable stator vanes in a gas turbine engine. The actuating lever is interconnected between and operates to activate one vane in each of two axially adjacent vane rows with one free end of the lever being rotatably attached to an actuation ring and the other free end being secured to one of the vane spindles. The second vane spindle is attached at an intermediate position of the lever, and a flexible link section of the lever is provided between the two spindles to accommodate differential movements in the lever experienced during movement of the actuation ring.</p> |
