Amphibious aircraft are needed in many areas in Indonesia that are difficult to reach by air transportation. With this amphibious aircraft, an amphiport is needed for aircraft to land on water. This amphiport requires a lower cost when compared to airport infrastructure. Due to the different landing sites, the load response that occurs on the seaplane structure at the time of landing will be different. In this paper, we will try to predict the pressure that occurs on the surface of the float when the aircraft lands on the water. The prediction is carried out by numerical simulation using software. Numerical simulations were carried out with several variations of angle of attack and several heeling conditions, namely 0, 5, and 10 degrees for trim by bow and trim by stern and 0, 5, 10, and 18 degrees for heeling conditions. This modeling has been verified by sensitivity meshing analysis. From the results of this study, it is obtained that the greater the angle of trim, the greater the maximum pressure that occurs on the surface of the float. Likewise with the heeling condition, the greater the angle of heeling, the greater the maximum pressure that occurs on the surface of the float. A structural assessment using the Finite Element Method (FEM) is recommended to determine whether the float structures are strong enough. The load or pressure obtained from the above research will be applied to the FEM. [ABSTRACT FROM AUTHOR] |
