Investigations of the thermal state of the GTE blades using a thermal vision system for tests with thermal management

Abstract

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.

Induction heating is the most effective heating method for thermocyclic tests and investigations of turbine blades and parts with a thermal barrier ceramic coatings. A new method is proposed for high-frequency induction heating of turbine blades and parts of gas turbine engines with thermal barrier ceramic coatings. The proposed method has been developed taking into account the electrophysical and thermophysical properties of materials in thermal cycling tests. There have been carried out thermophysical measurements, obtained the results of investigations of the nonstationary thermal state of the turbine blades and parts GTE with coatings using a thermal vision system for thermocyclic tests with thermal management. Also there have been carried investigations of the thermal state of the fan blade with the use of a thermal vision system and blade releasing method with thermal management for fan casing containment tests.
