method for measuring the thickness of hohlschaufeln turbines

摘要

P the invention relates to a method for measuring the thickness of the walls of the hollow parts. / p & & p & according to this process, a probe 11 constituted by an electrical winding whose impedance is modified by the characteristics genesis of a fluid introduced into the cavities 2 formed to the inside of the workpiece 1 is moved, to the outside of the workpiece 1, the variation in impedance of said probe 11 being measured and comparative to those obtained with the pieces of reference. / p & & p & the process according to the invention makes it possible to measure the thicknesses of the walls of the cooling channels households in the turbine blades of turbojets. / p
