Short abstract: The aerodynamic performance of a novel Fishbone Skin-Actuated-Camber (SAC) morphing wing design, which actuates its skin to change its effective camber, was studied both experimentally and numerically. Force-based experiments were conducted at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) to compare the performance of four morphing wing designs with different hinge locations, two ideal trailing edge flap wings, and one conventional trailing edge flap wing.

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.

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.

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.

Short abstract: Active flow control (AFC) devices can be utilized for stall mitigation, enhancing aerodynamic performance, and performing efficient maneuvers by altering the localized flow around different regions of a vehicle. A blown jet was installed along the upper surface of a flat plate delta wing half-span model with a 60° sweep angle in the University of Dayton Water Tunnel (UDWT).
