Abstract

The water load of amphibious aircraft is one of the main factors influencing the structure design. The water load of the hull were studied by numerical simulation and model experimental approach. The finite element model contains the air field. The local pressure variation and distribution were calculated with different sections of the bottom, structural weight and the speeds of entry water, and results were compared with tests. The results show that the numerical results are in good agreement with the model experimental value. Pressure distribution of two sections were obtained. It can provide reference for amphibious aircraft hull configuration design.
