In this paper, based on the experimental data of shooting range, the typical fragment damage forms of the wing with high fidelity are established under the water hammer damage principle of the thin-walled structure, and the flutter boundaries of different damage forms are studied based on the CFD&CSD two-way coupling method, and the survivability of the typical fragments of the wing is evaluated.
