Assessment of LOw NOise COnfigurations

Objective

ALONOCO will investigate the aerodynamic wing efficiency and the emitted noise from four different low-noise high-lift concepts of a regional aircraft. The concepts will be compared to a baseline configuration and ranked for down-selection. The analysis will be based on numerical simulations with high fidelity tools. The aerodynamic calculations will be based on steady and unsteady RANS, hybrid RANS/LES calculations at specified conditions up to maximum lift with the CFD solver Edge. Aerodynamic data will be supplied to the aero-acoustic analysis for which two different approaches will be used and compared. The proposed technical work is divided in three work packages over one year. The aerodynamic assessment will be carried out in WP1, the aero-acoustic analysis in WP2 and the overall synthesis in WP3. The maximum total budget is estimated to 300,000 Euro. The consortium consists of two Swedish partners, the research organisation FOI being the coordinator, and one university, Chalmers. Both partners are highly capable, well known and very active in national and European collaborative programs related to aerodynamic and aero-acoustic simulations.
