Abstract

A new method for low-drag high-lift system design based on viscous flow solvers was developed for Supersonic Commercial Transport wings within the EC research project EPISTLE. Two high-lift systems were manufactured for a large-scale wind tunnel model. The numerically predicted drag reductions (20% compared to a datum system) were fully confirmed by high Reynolds number tests. These drag reductions lower the low-speed noise for future SCT configurations by more than 4 EPNDB.
