Design and Analysis of Variable Wing Twist via Adaptive Morphing Skin
摘要
This paper investigates a novel concept for enhancing aircraft control and performance through a morphing wing-twist mechanism. The proposed system incorporates adaptive geometry with a flexible skin, showcasing advancements in morphing technology. Initial research involved finite-element analysis to demonstrate the viability of this concept. Subsequent to this studies, the concept was compared to a fully rigid model tested in a wind tunnel. Moreover, baseline models were manufactured with traditional ailerons at deflections of ± 10, ± 20, and ± 30 degrees to compare roll control moments. In addition, the concept was integrated into a small-scale remotely controlled aircraft for flight testing. The findings suggest that the morphing wing concept is both practical and effective, offering a promising platform for improving advanced aircraft control. Results showed that the design outperformed traditional approaches under certain test conditions, demonstrating sufficient flexibility in twist, resistance to aerodynamic forces, and minimal surface distortion during flight.
