In order to conform to the dimensional tolerances of wax pattern die-profile for turbine blade in investment casting process, an optimization method of geometric parameter for turbine blades based on inverse adjustment was proposed. The geometric parameters for optimizing were extracted, and the bending and torsional deformation can be compensation. Therefore the nonlinear deformation compensation during solidification and cooling procedure can be efficiently realized. This method finally exhibits its advantage over the traditional linear scaling method. It set the theoretical foundation on optimization method of die-cavity for turbine blade. The die-profile optimization system which was developed in this paper proves better effect for the die-cavity design.

The precision of complex ceramic core is one of the essential factors for hollow turbine blade manufacturing, which has a significant impact on the development of the modern aircraft engine. In terms of the low precision of ceramic core formation, this paper proposes an approach through measuring the data from a group of ceramic cores, to study the computational methods for displacement field, deformational feature decoupling, and structural shrinkage ratio. Based on modeling and analysis of decoupled deformational features and the uneven structural shrinkage ratio, this paper proposes an inverse design method and optimizes the design of the die profile for ceramic core. The applicability of this method is validated using numerical simulation data and experimental results.
