FIELD: measurement technology; check of profile and position of turbine working blades.
SUBSTANCE: check of blade profile form is effected by matching the templet with blade surface in preset section. Templet is moved in plane perpendicular to theoretical axis of blade. Position of blade profile in preset section is checked relative to theoretical axis of blade in tangential and radial directions. Thus deviation of real axis of blade from theoretical axis is checked. Blade is secured in retainer slot for turning around theoretical axis. Templet is moved in tangential and radial directions and blade is turned till they are matched completely. Deviation of templet from initial position as well as angle of turn of blade are noted in both directions.
EFFECT: enhanced reliability and increased informative capacity; extended functional capabilities; avoidance of reject.
