System Advances in Nacelle Technology Aerodynamics (SANTANA)
SANTANA is a collaborative programme focused on the development of aerodynamic technologies for the design of advanced, Ultra High Bypass Ratio (UHBR) power plant nacelles.
The nacelle on a modern high bypass ratio engine is a significant contributor to power weight, and owing to its size, can also have a marked impact on aircraft fuel burn performance. Targeting nacelle components for next generation aircraft, this programme exploits new lower weight structural designs, to reduce performance losses associated with installed nacelle systems. The programme also develops advanced aerodynamic testing methods, improvements to laminar-turbulence modelling and improves testing facilities within the UK.
These advancements are essential to achieve the global ACARE (Advisory Council for Aeronautics Research in Europe) 2020 and 2030 entry-into-service emissions targets for noise and fuel burn.
SANTANA’s partners comprise UK industrial organisations: Bombardier, Belfast; Aircraft Research Association Ltd (ARA), Bedford; and S&C Thermofluids Ltd, Bath; and aerodynamics research teams at City University, London and Imperial College, London.Download the System Advances in Nacelle Technology Aerodynamics (SANTANA) case study
