The Influence of Azimuth Orientation of Crystallographic Axes on Thermoelastic State of a Gte Blade with a Vortex Cooling System.

The paper addresses the temperature and thermoelastic states of a single-crystal blade with a complex vortex cooling system and passages for cooling air outflow. The problem of determination of stress-strain state of the blade at hand under the action of temperature fields and centrifugal forces is solved by the finite element method. The authors study the influence of azimuth orientation of crystallographic axes on the distribution and magnitude of thermoelastic stresses in the blade volume. [ABSTRACT FROM AUTHOR]
