The influence of single-crystal structure material azimuthal orientation on stress strain state and strength of high-temperature gas turbine blades
The application of single-crystal structure material for cooled turbine blades makes it possible to increase of gas turbine engines' life to a considerable extent. The current Ni-base single-crystal structure materials have anisotropic properties. These characteristics are must be taken into account for stress strain state (SSS) and strength calculations. The influence of single-crystal structure material azimuthal orientation on SSS, strength and low cycle fatigue of turbine blades is investigated by finite element method.
