Abstract

This work presents a multi-objective optimization framework based on a genetic algorithm (GA) for aircraft morphing wing trailing sections made of shape memory polymer composites (SMPCs) based varying height corrugated structure. A morphing wing trailing section is attached to the main wing without any external discontinuity. It offers smooth operation of the aft section repeatedly over the entirety of the flight envelope. The primary variables for the optimization method considered in this work are SMPC ply orientations, number of plies, and number of corrugation elements. The constraint imposed on the structure is the deflection of the trailing section under maximum air pressure load. These variables affect shape memory behavior, structural integrity, and weight of the morphing wing trailing section, and they, in return, provide constraints on the SMPC-based corrugated structure. An equivalent plate formulation has been used to obtain effective corrugation properties of variable amplitude corrugated structure. Optimization work has been carried out on two different NACA 6 series airfoils to draw comparisons and ascertain the effectiveness of the framework.

优化基于形状记忆聚合物复合材料的波纹变形翼襟翼结构

本文提出了一种基于遗传算法的多目标优化框架，用于基于变高度波纹结构的形状记忆聚合物复合材料（SMPCs）飞机变形机翼后截面。变形翼尾段附着在主翼上，没有任何外部间断。它在整个飞行包线上提供了尾部部分的平稳操作。本工作中考虑的优化方法的主要变量是SMPC层向、层数和波纹元件的数量。施加在结构上的约束是最大气压载荷下尾段的挠度。这些变量会影响变形翼尾段的形状记忆行为、结构完整性和重量，反过来，它们也会对基于smpc的波纹结构提供约束。采用等效板公式计算了变幅波纹结构的有效波纹特性。对两种不同的NACA 6系列翼型进行了优化工作，以进行比较并确定该框架的有效性。
