FIELD: measuring.
SUBSTANCE: invention relates to the technology of controlling accuracy in production of shrouded working blades of turbomachines. When implementing the method of controlling the accuracy of making shrouded blades of turbomachines by swirling the blade in order to measure its torsional rigidity, the twisting moment is applied by means of a fork through the radius conjugations of the shroud. Dependence of the feather twist angle on the applied moment is automatically determined and fixed by a strain gauge in which the shank is fixed.
EFFECT: increasing the accuracy and reliability of assessing the performance quality of blades, ensuring the identity of blades in terms of performance properties.
