AI Technical Summary
Traditional metal flutter models have a large mass, leading to excessive weight issues and making it difficult to design high-speed flutter models for small aspect ratio wings while ensuring stiffness.
A flutter model of a small aspect ratio wing stacked structure was designed using composite materials. The stiffness of the wing was simulated by stiffness equivalence and variable thickness plate structure. Combined with lightweight foam structure and counterweight, the stiffness and modal characteristics of the model were ensured to match those of the real wing.
While reducing the model weight, it accurately simulates wing stiffness and modal characteristics, solving the problem of excessive weight in traditional models and achieving accurate simulation of flutter models.
