The paper presents an integral core/shell fabrication of ceramic casting mould for hollow turbine blades by combining SL (Stereolithography) with gelcasting. This method could guarantee the positional accuracy between ceramic cores and shell, thus achieving the rapid fabrication of complex turbine blade castings. The paper focuses on the design of resin mould for gelcasting, the preparation of ceramic slurry, the pyrolysis of resin prototype and the sintering of ceramic green body. The feasibility and effectiveness of above mentioned method were verified through successful manufacturing of hollow turbine blades with double-walled structure.

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.
