摘要
安全、稳定、高效是当前飞机机翼设计领域重点关注的问题。机翼是提供升力的主要部件之一,可变形机翼在改善飞机整体性能方面有巨大潜力。以智能材料为代表的新材料的发展对机翼柔性蒙皮、驱动装置、控制技术以及轻量化结构产生了革命性的变革,拓展了手性拓扑结构的应用范围。基于手性拓扑结构、飞机机翼的气动性能分析、先进的制备工艺等技术而设计的变形机翼,可在不同飞行速度、飞行坡度以及周围流场改变其机翼形状,从而提高飞行效率,这是飞机机翼结构设计的前沿领域,也是未来重要的发展方向。本文介绍了手性超结构的设计方法及当前的研究现状,总结阐述了当前国内外基于手性拓扑结构设计的可变形机翼的研究进展,为我国可变形飞机机翼的设计提供参考。
Safety,stability and efficiency are the key issues in the field of aircraft wing structure design.Wing is one of the main components to provide lift,and deformable wing has great potential in improving the overall performance of aircraft.The development of new materials represented by smart materials has revolutionized the wing flexible skin,driving device,control technology and lightweight structure,and expanded the application range of chiral superstructures.The deformable wing designed based on chiral structure,aerodynamic performance analysis of aircraft wing and advanced preparation technology can change its wing shape at different flight speeds,flight slopes and surrounding flow fields,so as to improve flight efficiency,which is not only the frontier field of aircraft wing structure design,but also an important development direction in the future.This paper introduces the design method and theoretical method of chiral superstructures,and summarizes the research progress of deformable aircraft wing at home and abroad so as to provide reference for the domestic design of deformable aircraft wing.
