| Abstract: | The helicopter bottom shape was simplified as a rectangular plate. Based on the classical hydrodynamic impact theory, the simplified rigid motion equations were established, and the estima- tion of impcat loads and pressure distribution were developed. The results were compared with for- eign references, and the accuracy could satisfy the requirements of engineering. |
