ACUHRA Advanced Cavities Using High Resolution Additive
Around 15% of total losses in turbine efficiency can be linked to leakage flows through seals that are installed in the flow paths of the turbine. New manufacturing processes based on additive manufacturing offer a great opportunity to improve both the sealing capability and the control of the swirl factor during re-ingestion of the combusted products.
The ACUHRA project plans to produce lightweight components for swirl control using additive manufacturing. The ultimate aim is to promote the design of more efficient low-pressure turbines. The project will combine high-fidelity computational fluid dynamics tools and experimental tests to evaluate the design of the new components.
The ACUHRA stakeholders are the University of Nottingham, the University of Bath and Added Scientific Limited.
