Reversing Design Methodology of Ceramic Core for Hollow Turbine Blade Based on Measured Data

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 …
