摘要

在这项研究中,研究了自主变形翼概念的设计和开发。这种变形机翼是在Smart-X项目的范围内开发的,旨在展示飞行性能优化。该研究提出了一种新颖的分布式变形概念,采用6个可变形后缘模块,由弹性体材料连接的相互连接的三角形皮段,允许沿翼展的局部升力分布无缝变化。开发了FSI结构优化工具,以实现这种优化设计,并产生最佳的玻璃纤维编织材料层压板设计,能够达到目标形状并最小化驱动负载。对嵌入式作动器的运动学模型进行了分析,选择了一种传统的作动器设计,使其在要求的负载下连续工作,并在带宽、作动力和行程方面满足静态和动态要求。本研究为Smart-X下一阶段的设计做准备,完善变形机构设计,建立风洞测试的功能演示器。

Design of a Smart Morphing Wing Using Integrated and Distributed Trailing Edge Camber Morphing
In this study, the design and development of an autonomous morphing wing concept were investigated. This morphing wing was developed in the scope of, the Smart-X project, aiming to demonstrate in-flight performance optimisation. This study proposed a novel distributed morphing concept, with six Translation Induced Camber (TRIC) morphing trailing edge modules, inter-connected triangular skin segments joined by an elastomer material to allow seamless variation of local lift distribution along the wingspan. An FSI structural optimisation tool was developed, to achieve this optimised design, and to produce an optimal laminate design of fibre Glass weave material, capable of reaching target shapes and minimise actuation loads. Analysis of the kinematic model of the embedded actuator was performed, and a conventional actuator design was selected to continuously operate at the required load and fulfil both static and dynamic requirements in terms of bandwidth, actuation force and stroke. Preparations were made in this study for the next stage of the Smart-X design, to refine the morphing mechanism design and build a functional demonstrator for wind tunnel testing.
