METHOD OF DETECTING TORQUE AND BENDING DISPLACEMENTS OF FACES OF BLADES OF COMPRESSOR WHEEL Russian patent published in 2008 - IPC G01B7/14 

FIELD: measuring technique.

SUBSTANCE: method comprises setting a single-turn vortex current converter with three sensors made of a section of conductor, arranging the sensors so that the conductors form a equilateral triangle, simultaneous pulse sampling of measuring circuits one time for a revolution of the rotor of the compressor at a moment when the center of the lock of the blade is located under the point of the origin of the coordinate system corresponding to the center of the triangle formed by sensors, recording the numerical codes of the measured signals of the converter. The codes are supplemented by the result of modeling of the radial space between the blade faces and stator by calculating deformations of working wheel and stator under the action of centrifugal forces and temperature with the use of information on the speed of rotation of the rotor of the turbine matching and temperatures of fluid (gas) and stator.

EFFECT: enhanced precision.
