Abstract

An investigation of marine UAV performance with various designs have done successfully. The analysis was based on resistance criteria identification both aerodynamically and hydrodynamic. The calculations were conducted with the assistance of image processing as the experimental attempt and High-Fidelity Computational Fluid Dynamics (CFD) software code to simulate the fluid flow on the fuselage designs, pontoons, and image processing. Both methods compared to acquire the silver line in which way they can collaborate to create new way of testing. Furthermore, mathematical calculations and Image processing works refereeing were also performed as the attempt for validations and conclusion

Abstract

An investigation into the hydrodynamic force and seakeeping of single-to-twin after ship hull (STASH) and multi-hull geometry was done successfully. STASH is characterized by its monohull-shaped design in the fore part and twin hull in the rear part creating unique performance, especially seakeeping which being the focus study to provide seaworthiness. The method of accomplishing this study was through computer simulation using Maxsurf: Motion for seakeeping and hydrodynamic force analysis. The overall results were compared with published data and mathematical models for validation purposes. The results are believed to be useful for the development of the ship design and performance.
