FIELD: machine building.
SUBSTANCE: present group of inventions relates to devices for measuring dimensions of component parts in turbomachines. Disclosed method of measuring deformation of a component part in a turbomachine comprises inspecting profile of a core in three dimensions using a 3D model of profile of part of a reference component part; inserting rod into endoscopic hole of turbomachine housing; positioning and fixing profiled part of rod on part of inspected component part corresponding to part of reference component part; inserting endoscope into housing of turbomachine; measuring deformation of part of the inspected component part by means of endoscope, retrieving rod from turbomachine and reinspecting profile of rod in three dimensions to make sure that it was not deformed in housing of turbomachine. Device for measuring deformation of a component part in a turbomachine comprises a rod, part of which has a profile corresponding to profile of part of reference component part of same type as analysed part, wherein said part of rod additionally contains a visual mark for measurement of distance made along its length. Further, said device comprises means of fastening and positioning said part of rod in a fixed position and aligned with part of analysed component part corresponding to part of reference component part.
EFFECT: present group of inventions provides higher accuracy and simplifies procedure of determining initial deformation of an inspected component part of a turbomachine.
