Thermophysical measurements during thermal cycling of gas turbine engine blades with ceramic coatings
Annotation
A design-experiment method is proposed for high-frequency induction heating of turbine blades and models of combustion chamber flame tubes of gas turbine engines with heat-resistant ceramic coatings. The proposed method has been developed taking into account the electrophysical and thermophysical properties exhibited by the materials in thermal cycling tests. The results of thermophysical measurements, design-experiment studies of the nonstationary thermal state of the parts with coatings with the use of a thermal vision system, and thermal cycling tests of rotating blades and models of flame tubes with heat-resistant ceramic coatings are presented.
