Different engineering-disciplines are involved during the design and optimization of turbine blades, to ensure that the blades
However, only after all theses criterias are met, it's checked, if the blades is manufacturable at all. Often, the blade design has to be revised essentially.
The objective of the project Titanium Aluminide Turbine Toolbox TATT is to reduce the time-to-production for new blades by considering the manufacturing restrictions already at early design stages (e.g. during the aerodynamic design). A new, network-based design and optimization tool will be developed. Exemplarily, low pressure turbine blades of the high-performance material Titanium-Aluminide are regarded, because of the increasing usage in next generation aircraft engines. Based on the optimization program AutoOpti, developed by the Institute of Propulsion Technology, the complete design process chain - from aerodynamic shape optimization via structural design and blade reliability through to simulation of the blades' casting process - is integrated.
The participating project partners
pool and connect their core expertises in the new tool with specialized simulation programs. Eventually, a new TiAl-turbine blade is designed and optimized in its entirety. For validation, the blades are casted and experimentally investigated in the turbine test rig RGG.
