Corrugated Winglets Efficiency: A Numerical Study
Year: 2025
Type: article
Abstract: This research compares the efficiency of raked and blended wingtip devices performance by modifying the winglet tip. The study validates these modifications against the baseline wing's aerodynamic properties. The simulations reveal a strong correlation between the size of the tip vortex and the wing's lift, drag and pitching moment. According to the study, winglet tip optimisation is crucial for maximising lift and reducing drag. Corrugated tips demonstrated the best aerodynamic performance, enhancing both flight range and endurance. The number of winglet research papers has shown the best of raked and blended winglet gives 5% more lift coefficient than the conventional wing. According to the present research, it is noted that the winglet with corrugation gives 2% more than the exiting raked and blended. Comparatively the corrugation winglets give totally 7% than the conventional wing. By using corrugated winglets will reduce the drag in the flight range without affecting the lift.
