FACILITY TO TEST GEOMETRICAL PARAMETERS OF BLADES OF VANE CASCADE OF MACHINE Russian patent published in 2001 - IPC

FIELD: instrumentation. SUBSTANCE: invention can be used to test geometrical parameters of blades and interblade ducts of vane cascade (impellers and guiding apparatuses) of machine. Proposed facility includes functionally coupled base, supporting unit for tested cascade mounted for rotation about vertical axis and movable with reference to base, measurement unit and unit converting and presenting information coupled to it, linear translation transducer mounted for reciprocal movement along longitudinal axis of base and for angular deviation with regard to vertical axis in plane perpendicular to plane of tested impeller. Unit converting and presenting information incorporates electron processing unit. Measurement unit has source and detector of laser radiation optically intercoupled. EFFECT: increased precision and objectivity of information reading, reduced labor input to process of test. 1 dwg
