Variations in The Distance Between Hulls that Affect the Resistance of The Floating Pontoon N219

Abstract

An amphibious plane is an aircraft to carry out cargo delivery and an aircraft for emergencies to reach remote islands in the archipelago. A pontoon or buoy is a hull that is useful as a bearing for landings in water areas. This is done to assist aircraft landing without using an airplane runway. This research aims to create a new configuration of the distance between one pontoon and another. Numerical calculations and analysis are useful for seeing the characteristics of the floating pontoon design's resistance. An investigation of interference waves was also carried out in this study to validate the experimental data generated by the pontoon hull. Numerical calculations are carried out on the CFDSOF application to predict hull resistance with three variations to the floating pontoon's separation distance. The simulation is carried out at the Operating Empty Weight condition on the Indonesian Aerospace aircraft with the IAe N219 model. The results show that the Froude Number speed is between 0.3 to 0.8. There is a reduction in drag on the hull so which makes takeoff operations easier.
