Slat-Inspired Reversible Wing for Stopped-Rotor Vehicles

Reversible morphing wings, which can exchange the leading and trailing edges, expand architectural possibilities for aerial robotics (e.g., stopped-rotor configurations). However, few designs are scaled for uncrewed aerial vehicle (UAV) applications or effectively address the coupled aerodynamic and structural challenges of morphing. As such, we present a novel reversible wing design that uses rigid parallelogram slats mounted on a flexible substrate, creating a compliant yet aerodynamically robust structure. One-way fluid-structure interaction simulations validate the wing's structural performance under airflow. Compared to other reversed-flow wings, the proposed configuration doubles reverse-flow performance relative to a Clark-Y wing and improves upon the 0° angle of attack performance compared to other reversible morphing wings.
