Short abstract: The disappearance of the tip vortex in the near wake of a wing challenges conventional aerodynamic theories and presents new opportunities for drag reduction. Recent computational studies suggested that the PRANDTL-D3C wing—a swept, multi-element, and tapered wing with a bell-shaped lift distribution—exhibits this tip vortex disappearance.
Variations in the Wake Structure of Non-Elliptical Lift Distributions Near Wingtip

Short abstract: Non-elliptical lift distributions, particularly bell-shaped distributions with extended spans, have shown potential to disrupt conventional tip vortex roll-up, even eliminating trailing vortices in the near wake. This study investigates the aerodynamic performance and near-wake characteristics of four wing configurations: a baseline untwisted wing, an elliptically loaded wing, and two nonelliptical lift distributions.
Experimental Investigations of a Dual-Mode Skin-Actuated-Camber with Embedded Twist (SACET) Morphing Wing
Citation: 77. Schreyer, Grace A., Grace N. Selm, Julian A. Pabon, and Sidaard Gunasekaran. "Experimental Investigations of a Dual-Mode Skin-Actuated-Camber with Embedded Twist (SACET) Morphing Wing." In AIAA SciTech 2026 Forum, p. 0256. 2026. https://doi.org/10.2514/6.2026-0256
Short abstract: A dual mode Skin Actuated Camber with Embedded Twist morphing wing is developed to approximate a bell-shaped lift distribution and the associated tip vortex free wake. Three morphing concepts are conceived for a rectangular wing using simple geometric models that link actuator motion to local rib twist.
