The work represents the approaches for designing the digital casting process of turbine blades. The development of the mathematical model for determining the non-stationary temperature distribution in the "furnace-moulding-flask-filler-metal-stopper" process system has appeared to be the core of the digital blade manufacturing process considering particular structural, geometry and thermal-physical features of this system. The approbation of the developed mathematical model as well as the computer designing methods under the pilot production conditions through manufacturing of the GTE turbine blades has demonstrated the decreased amount of defects in the macrostructure of blanks of turbine blades with the longitudinally-oriented and single-crystal structure by 30% in total. |
