Anotace
The proposed project is focused on the development and subsequent implementation of advanced precision casting technology of cast wheels for new aircraft engines and axial turbocharger wheels. These engines are currently under development in PBS Velká Bíteš, a.s., and higher engine efficiency as well as significantly higher durability of key components is required. These design requirements lead to the need for the introduction of improved temperature-resistant materials and also place great emphasis on the mechanical properties of these materials, especially interaction of the fatigue and creep. In the production of the ceramic shell moulds in most new types of castings water based binding agent will be applied in comparison to the binding agent currently used, which is mainly alcohol based. This will reduce the amount of alcohol vapors released to the atmosphere and thus significantly improve the environmental situation.
