Definitions

  • the disclosed invention relates to a system and method for actuating variable position guide vanes in a turbine engine. More specifically the invention relates to actuating the variable position guide vanes by moving a structure in operable communication with a plurality of the variable position guide vanes.
  • Aerodynamic efficiency of the vanes of a turbine engine is an important factor in the overall operational efficiency of the engine. Operators rotate the vanes in an attempt to improve the aerodynamic performance at different power settings of the turbine. Systems and methods to improve precision and control of rotation of the multitude of vanes in a turbine engine is of value to operators in the industry.
  • a turbine variable position guide vane actuation system includes, a plurality of variable position guide vanes, a plurality of actuators and each actuator is in operable communication with one of the plurality of variable position guide vanes, and at least one structure in operable communication with a plurality of the plurality of actuators and movable parallel to an axis of the turbine.
  • the method includes, moving a structure in a direction parallel to an axis of a turbine and rotating a plurality of turbine variable position guide vanes in operable communication with the structure.
  • Turbine engines such as, gas turbine engines for power generation, for example, have stationary guide vanes and rotating guide vanes. Compressed air flows past both types of guide vanes during operation of the turbine. Performance of the turbine can vary depending upon, among other things, angles of the stationary guide vanes. During different operating conditions, however, different guide vane angles may be preferred. As such, having guide vanes, wherein angles of the vanes are variable, has benefits to the turbine operator. Systems and methods for adjusting the variable guide vanes are described in detail below.
  • the system 10 includes, a plurality of variable position guide vanes 14 with an actuator 18, depicted herein as a lever, attached to each one of the variable position guide vanes 14, and at least one structure 22, depicted herein as a plate, engaged with a plurality of the levers 18.
  • the plate 22 is configured to be moved in a direction parallel to an axis of the turbine 26 to cause rotational motion of each of the levers 18, engaged therewith, and consequently to rotate the variable position guide vanes 14 attached thereto.
  • FIG. 2 a cross sectional view through one of the variable position guide vanes 14, the lever 18 and the plate 22, of FIG. 1 , along arrows 2-2, is shown.
  • a bearing 30 rotationally mounts each of the variable position guide vanes 14 to a casing 34 of the turbine 26.
  • a pin 38 extends from each of the levers 18 to engage with a slot 42 of the plate 22.
  • a sleeve 46 can be rotationally engaged with each of the pins 38 to reduce frictional engagement between the pins 38 and walls 50 of the slots 42.
  • the lateral or radial instability (as the case may be), that occurs in typical systems that have the plate 22 move circumferentially with respect to the turbine 26, can be reduced.
  • embodiments disclosed herein can more easily control the precision of the rotational motion of the variable position guide vanes 14. This ease of control is due to a reduced offset between the linear motion of the plate 22 and the rotational motion of the variable position guide vanes 14, as compared to a circumferential motion of a plate. This control precision can be maintained in alternate embodiments as will be described below.
  • FIG. 3 an alternate embodiment of a turbine variable position guide vane actuation system 210 with a plate 222 disclosed herein is illustrated.
  • the plate 222 forms a ring perimetrically around a significant portion of the turbine 26.
  • the plate 222 can be a continuous ring that encircles the casing 34 and actuates all of the levers 18, or be segmented to actuate any selected number of levers 18 desired.
  • FIG. 4 yet another alternate embodiment of a turbine variable position guide vane actuation system 310 with plates 322 disclosed herein is illustrated.
  • the plates 322 are a variation of the structures 22.
  • the plates 322 are configured to actuate levers 18 on multiple stages simultaneously.
  • the plates 322, actuate variable position guide vanes 14 from different stages 312A, 312B and 312C of the turbine 26.
  • Such a "ganged” system can significantly simplify the linkages required to actuate a multitude of the variable position guide vanes 14 at once. Two or more stages can be “ganged” together forming one or more "gangs,” for example. This variation of the "ganged” system can also be used for the plates 222.
