| description | PROBLEM TO BE SOLVED: To provide a turbine that overcomes a problem of suboptimal control of adverse effects of windage on a last stage blade distal region resulting in a reduced blade life.SOLUTION: There are provided an axial flow turbine 10 and a method of operating the same. The turbine includes a last stage of rotating blades 12 located near a downstream end of the turbine 10 having a distal region 19 in an end of an airfoil 13 of the blades 12. A monitoring control system includes at least one sensor 22 in the distal region 19 of at least one last stage blade 12 for measuring at least one physical property of the airfoil 13, and a control element 24 capable of influencing at least one physical property of the distal region 19. The control system further includes a controller 20 for adjusting the control element 24 based on at least a measured physical property, and thus at least one physical property is controlled. |
