从结构设计角度看,机翼的柔性越大,结构重量可降低的幅度也越大,但是,柔性结构通常会带来一系列的耦合效应,给飞机飞行性能带来不利的影响。随着主动控制技术(ACT)在航空技术领域的发展,逐步使人们认识到结构的柔性在主动控制技术的支持下可以发挥更大的潜力。 From the perspective of structural design, the larger the flexibility of the wing, the lower the weight of the structure. However, the flexible structure usually brings a series of coupling effects, which adversely affect the flight performance of the aircraft. With the development of active control technology (ACT) in the field of aviation technology, it is gradually realized that the flexibility of the structure can exert more potential with the support of active control technology.
