Indicator for qualification of a turbine vane condition

摘要

Indicator (10) to qualify turbine blade condition,containing a longitudinal element,running essentially straight,with the first end and the second end,the first anchorage area,which is foreseen at the first end,second anchorage area (1b),which is foreseen at the other end,first measurement part (2),which is placed at the first fixing area,second measurement part (3),which is located in the second fixing area and runs essentially parallel to the first measuring part (2),each part of the measurement shall have one measuring surface each time,between which a turbine blade can be inserted in the measurement setting,the distance between the measuring surfaces corresponds to the minimum permissible width of the turbine blade in the measurement setting.
