Water-impact force analysis for Over-sea aircraft impacting water

When modern aircrafts above water flying over sea in a very low height, the flight height is limited by the sea state. Bad sea state can not only cause the attitude overturning and dropping into the water. In this paper, a impacting water flight mode of Over-sea aircraft is proposed. Based on the analysis on the water-impact force of the aircraft impacting water, how to choose proper configuration parameters and water-entry attitude angles of the wave protection slide in order to limit the water-impact overload to be acceptable and realize the over-sea flight in bad sea state, is researched.
