Amphibious plane which is based from aero-hydroplane is a kind of fixed-wing plane and it can take off from both water and land.Not only landing gear but also hull is assembled in it's fuselage, so the plane is useful in adjacent sea, alongshore, rivers, lakes, basins and so on.But complex water load also exist during taking off and landing.By preliminary analysis, the amphibious plane contact with water surface and wave will generate complex impact load and planing load when taking off planing and landing.This paper discuss water load test methods based on a certain amphibious plane, and analysis the effect of three degree of freedom test method and six degree of freedom test method to test results.The effect of different landing attitude、 landing speed and wave parameters to water load is analyzed by towing tank tests.The results provide some information for design of plane structural strength and research of high-speed marine wave impact load. |
