Abstract

Abstract

The effect of hydrodynamic impact on the amphibious seaplane is an important consideration in its structural designing and intensity checking. In addition, such impact is a major factor affecting its structural weight. By varying two parameters: drop height and drop weight in the experiment, the pressure and the change of the free surface of liquid for three different wedges are dynamically measured. In the present work, the local pressure distribution, the impact pressure changing with time and the variety of the free surface on several free-falling wedges have been investigated. These wedges have been chosen from the representative cross section of amphibious seaplanes commonly used worldwide. By comparing the experimental results, the conclusion is reached that the wedge with a flared cross section reduces the impact pressure effectively when the amphibious seaplanes land on intricate waves. This study is expected to offer valuable reference for the hull designing of the amphibious seaplane.
