Abstract: The design method of the hull of the huge amphibious seaplane for fire extinguishing and rescue is illustrated firstly, then the aircraft's water resistance, planning stability and motion response to rough water are investigated. The results show that the spray configuration is the main factor that affects the second hydro-resistance hump, and the precondition for the second hump is put forward. The characteristic of the trim response to different zones in the trim-speed figure is analyzed, and the stable boundary is also confirmed. By analyzing the effect of the wave length and the speed on the trim, heaving and vertical overload, the range of wave length corresponding to the strenuous exercise response of the plane on wave is confirmed.

Key words: amphibious aircraft, hull, hydro-resistance, planning stability, motion response on rough water
