AbstractMost of the current seaplanes don't consider seaworthiness. Therefore, it is difficult to use conventional seaplanes in islands. For example many small seaplanes have seaworthiness of only 0.3 meter height wave. This level of seaworthiness realizes only 35% of operating rate. LSA class seaplane that we are developing has the seaworthiness of about 0.6-0.7 meter height wave which is about 10 percent of body length. With this capability we able to achieve achieves the operating rate of about 70-75 percent. We able to fly it at almost all Fine day always can use. To meet this specification we optimize the hull shape to decrease the water running resistance and landing shock from the water impact. We have tested flexible float leg structre by FEM Simulation, water tank test on scale model and glide test of ultra-light-seaplanes.
