Abstract
A method for determining the outlet cross-section of a component including one or more turbine blades, in particular of a turbine blade twin, of a gas turbine, in which at least one closed outlet cross-section is measured between the turbine blades, and/or respective open outlet cross-sections are measured on the side of the at least one turbine blade, using a measurement device, wherein in order to determine the corresponding outlet cross-section its respective bounding walls are traversed by the measurement device along a measurement line.
Claims18
A method for determining an outlet cross-section of a component comprising two turbine blades extending between an inner and an outer platform, the method comprising:
- measuring at least one closed outlet cross-section between the two turbine blades using a measurement device;
- measuring an open outlet cross-section between a side of each of the two turbine blades and a side of one of the inner and outer platforms using the measurement device;
- and
- determining a corresponding outlet cross-section by traversing one of an open and a closed measurement line along respective bounding walls.
A device for determining the outlet cross-section of a component including at least two turbine blades of a gas turbine extending between an inner and an outer platform, the device comprising:
- a measurement device including an arm with a sensing device, said measurement device configured to move said sensing device over the blades and the inner and outer platforms and measure at least one closed outlet cross-section between the turbine blades and respective open outlet cross-sections between a side of one of said at least two turbine blades and a side of one of the inner and outer platforms, wherein bounding walls of the respective outlet cross-section are traversed by said sensing device along a measurement line;
- and
- a computer unit programmed to evaluate the measurement line and determine a corresponding outlet cross-section.
