Experience of CT Testing of Cooled Turbine Blades

I. A. Vainberg, E. I. Vainberg, S. G. Tsyganov

Conformity of the main problems of quantitative non-destructive testing of cooled turbine blades to information opportunities of CT inspection is shown. Numerous experimental examples of application of home CT systems of the ВТ series to certificating the sizes of internal structures and technology improvement of cooled blades turbine made of high-temperature alloys are given. It is shown that accuracy of the noncontact CT size measurements is not worse than 20 microns.
