| Abstract: | In order to investigate the water entry mechanism of typical components of helicopter and provide measured data to simulation modeling and verification, we carry out a series of research on vertical water entry tests of the helicopter typical components with different construction. Test design method and its process are presented, and test results are analyzed. It is shown that the structural elastic effect is obvious and the effect of air cushion cannot be neglected. There is a significant difference between the two effects on the peak pressure at different speeds. |
