Aerothermal Investigations on Turbine Endwalls and Blades

---

Project Summary

• a 20% reduction in turbine weight due to high-lift technology and shorter intermediate turbine ducts,
• a 1% reduction in CO₂ emissions due to an increase in turbine efficiency,
• a 20% reduction in time-to-market due to more efficient CFD approaches,
• a 10% reduction of aero engine costs.

• Decrease the amount of coolant flow required by establishing advanced cooling concepts in regions of separated flow, as well as in trailing edge, rotor tip and platform regions.
• Decrease specific fuel consumption for the entire engine via higher turbine efficiency obtained due to a combination of higher turbine entry temperatures and lower coolant consumption.
• Develop novel techniques to measure heat transfer in rotating systems and in unsteady flow.
• Establish a validation database, correlations and “CFD Best Practice Guidelines” for designing the entire annulus of a turbine component.
• Accelerate industrial design by developing CAD-to-Mesh tools for speeding up CFD processes.

Project Consortium and Partners

The AITEB-2 consortium is established by a total of 19 companies, universities and research institutions. It consists of seven leading European aero engine manufacturers and one major industrial gas turbine manufacturer, three leading European research institutions, one additional SME, five universities as partners and two universities as subcontractors. All partners in AITEB-2 were selected for the excellent capabilities in their respective areas and their experience gathered and documented already in the previous AITEB project. The project and consortium structure has been planned in order to take into account the complementarity of the partners experience and resources on the following levels: between industry and research institutions: Joining technical expertise and sharing test facilities; between universities: Cross-fertilisation due to co-operation and exchange of knowledge; between all partners: Sharing cost for conducting high quality research.

Project Status

Turin, Italy - March 4th-5th 2009 After 48 months of intensive scientific work, the project is almost finished. Since some experimental and numerical tasks are still in progress, the project is now going into extention. The meeting, which primarily would have been the project's final meeting, was kindly hosted by Avio, subsidiary company of the Fiat group. Thanks for the hospitality and the organisation to Stefano Zecchi, Avio's representative in the project.     Previous meetings...
