摘　　要：针对主动气动弹性机翼(active aeroelastic wing,简称AAW),基于遗传算法发展一种可以同步考虑结构优化和配平关系优化的综合设计方法,并在采用了AAW技术的战斗机的设计中得到了应用。以结构质量最小化为目标,以控制面偏转、铰链力矩、翼根载荷和临界颤振速度为约束条件,在多种平飞滚转机动状态下对战斗机机翼进行优化设计,并与传统的单控制面设计方法进行了比较。结果表明,AAW技术通过多控制面之间的协调偏转,能够充分利用结构柔性,在提高机动性能和减少结构质量方面有明显的优势。An integrated design methodology considering the simultaneous optimization of structure and trim is developed for the active aeroelastic wing（AAW）,based on the genetic algorithm.This method is applied to the design of fighter configuration employing AAW technology.The optimization design for the wing of fighter aircraft is conducted in multiple maneuver conditions of level-flight with roll.The objective is to minimize the structural mass subjected to the constraints of deflections of control surfaces,hinge moments,aerodynamic loads acting on wing root and critical flutter speed.A comparison between the new method and traditional method which utilizes a single control surface,is also presented.The results demonstrate that AAW technology takes the full advantages of structural flexibility by the coordinated deflections of multiple control surfaces,and has significant merits in improving maneuverability and reducing structural mass.
