Flutter model with active flexible front edge

The invention relates to a flutter model with an active flexible front edge and belongs to the technical field of aeroelasticity tests. The flutter model comprises a wing beam (1), the front edge, a main box section and alloy wires (9). The wing beam penetrates and is fixedly connected with the interior of the main box section. The front edge is hinged to a butt joint board of the main box section. The front edge is connected with the main box section through the multiple alloy wires (9). The alloy wires are made of a shape memory alloy. Retraction of the alloy wires is controlled to control the front edge to turn over relative to the main box section. Through temperature control over the shape memory alloy, the shape of the front edge of a wing is changed, and therefore the wing profile and the attack angle of the wing are changed. Through the unique shape memory characteristic of the shape memory alloy, control of an operation system over the deflection of the front edge in the prior art is replaced, and th
