Analytical and experimental studies have been made to determine the impact accelerations of axially symmetric bodies during landing on water surface. The formulas for the maximum impact accelerations are derived and the history of the acceleration can be calculated easily by the present analytical results. Spherical and conical models were used for the present experiments. The water impact accelerations of these models were measured by accelerometers. The agreements between the experimental and the theoretical results are satisfactory.
