With the help of the developed 3D CFD-model calculated thermal state (full three-dimensional temperature field) cooled blades gas turbine engine accounting conjugate heat transfer between the working gas, the blade body and the cooling air allows you to calculate the thermal stress state of the blade (Fig. 1).
Fig. 1 Model of the blade, interscapular channel and temperature field
The developed model allows to identify local hot spots.
