A numerical study of lift-enhancing tabs on three-dimensional high-lift systems was performed. Lift-enhancing tabs have been computationally shown to improve the lifting capability of high-lift systems at three leading-edge sweep angles, 0, 15, and 30 deg. The lift coefficient at 10-deg angle of attack is increased by 5, 27, and 36%, respectively. The results for the unswept case were compared with experimental data and the lift increments caused by the tabs agreed closely.
