Method and system for producing blades of a machine interacting with a fluid

A method for producing blades of a fluid-driven machine, the method comprising:

• providing or specifying one or more blades that are shaped, geometric deviations from a target shape are determined in an examination step for one or more shaped blades, a respective first deviation evaluation is assigned to one or more determined geometric deviations from the target shape for each blade with respect to at least one of an aerodynamic or mechanical consequence thereof,
• one or more corrective measures, each including an expenditure evaluation, are assigned to one or more determined geometric deviations from the target shape for each blade, wherein the one or more determined geometric deviations are in a form of at least one of:
• an elevation, a depression, or a recess, a respective second deviation evaluation is assigned to determined geometric deviations for each blade with respect to the aerodynamic and/or mechanical consequences thereof, taking the one or more corrective measures into consideration, and
• for one or more of the determined geometric deviations the second deviation evaluation is, or the first and second deviation evaluations are, linked to the expenditure evaluation, and the one or more corrective measures to be carried out are determined from the result of the linkage.

A method for producing blades of a fluid-driven machine, the method comprising:

• providing or specifying multiple blades that are shaped, geometric deviations from a target shape are determined in an examination step for multiple shaped blades, a respective first deviation evaluation is assigned to one or more determined geometric deviations from the target shape for each blade with respect to at least one of an aerodynamic or a mechanical consequence thereof,
• one or more corrective measures, each including an expenditure evaluation, are assigned to one or more determined geometric deviations from the target shape for each blade, wherein the one or more determined geometric deviations are in a form of at least one of:
• an elevation, a depression, or a recess, and
• for one or more of the determined geometric deviations the deviation evaluation is linked to the expenditure evaluation, and groups of two or more blades, for which the expenditure evaluation exceeds an established threshold and for which the deviation evaluations differ from one another by less than an established value, are assigned to one another for a shared use in a wind turbine based on the result of the linkage.

A system for producing blades of a fluid-driven machine, comprising

• an examination device for determining one or more geometric deviations from a target shape for one or more shaped blades,
• a device for determining a deviation evaluation of one or more determined geometric deviations from the target shape for each blade with respect to one or more of an aerodynamic or a mechanical consequence thereof,
• a device for assigning one or more corrective measures, each including an expenditure evaluation, to one or more determined geometric deviations from the target shape for each blade, wherein the one or more determined geometric deviations are in a form of at least one of:
• an elevation, a depression, or a recess, and
• a linking device for linking a deviation evaluation of one or more of the determined geometric deviations to the expenditure evaluation for one or more determined corrective measures and for determining the one or more corrective measures to be carried out from the result of the linkage.
