Innovative short and slim nacelle design
The ultra-high bypass ratio (UHBPR) aero engines approach represents a viable technological pathway, delivering increased propulsive efficiency through operation at reduced specific thrust, enabled by increased engine diameter. However, this poses significant challenges concerning the aerodynamic drag of the isolated nacelle and the potential for interference effects. The EU-funded ANACO project will enable the multi-objective optimisation of short and slim nacelle designs for the next generation of UHBPR aero engines, minimising overall drag. The project will use advanced numerical methods before downselection for isolated and high-speed wind tunnel tests to optimise these designs, improve experimental data quality by developing innovative measurement techniques and provide design rules and guidelines.
