ANACO – Advanced Nacelle Aerodynamic Optimisation

The ANACO project recently completed the main test entry in the ARA Transonic Wind Tunnel (TWT). This testing comprised detailed drag measurements coupled with discrete surface pressure and shear stress measurements, Pressure-Sensitive Paint (PSP), and culminated in the first deployment of Particle Image Velocimetry (PIV) for boundary layer measurement in the TWT.

Over the course of the test entry, the drag and surface pressure characteristics of 4 different nacelle geometries were investigated. This generated a large database which will be used to validate CFD and related design tools developed within the programme by Cranfield. ARA wishes to thank the consortium for their efforts during the test entry and looks to continued collaboration for the data analysis and dissemination stages. 

This project has received funding from the Clean Sky 2 Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 820997. For further information please contact
