Numerical simulation for floater design on the 17 passengers capacity of N219 amphibian in static and dynamic condition

Abstract

The sea toll allows the formation of marine tourism transportation, such as a floatplane to be developed in the Indonesian Archipelago Region. This research develops a floater design for a floatplane with a capacity of 17 passengers of N219 Amphibian. Design configurations were coded by LPDP-01 to LPDP-09. The step study where was (a). the weight of main and nose landing gear (365.56 kg) were smaller than twin floater (2 x 369 kg); (b). the method numerical analysis was by using trim even keel condition for Savitsky method to known the draft, volume and displacement of 9.8 meters and 11.8 meters length as first iteration of analysis for static condition; (c). and the porpoising effect was included in the figure of results as second iteration of analysis for dynamic condition. The final result of numerical simulation shows that the best design was the Floater LPDP-09 with dimension: Length = 9.8 m, Beam max extend = 5.476 m, Height = 1.356 m, and Displacement = 7,018 kg.
