PRELIMINARY DESIGN OF DUCTED NOZZLE PROPELLER IN PROPULSION SYSTEM OF CATAMARAN FLAT PLATE BOAT WITH THRUST VECTORING VARIATION

ABSTRACT

The tourism sector is one of the economic supports in Banyuwangi Regency. So with Covid-19 pandemic, tourist visits decreased drastically. To help the problem, they need an innovation that can attract visitors to visit. One solution is a Flat Plate Bottom Glass designed with safety, comfortable, efficient and sophisticated for underwater panoramic tourism facilities. This paper shows the Ducted Nozzle Propeller thrust vectoring ship propulsion innovation. This can be a solution for the thrust to focus and be used entirely to move the ship. Then the propulsion system on the ship becomes effective. The method used in this study used CFDs (Computational Fluid Dynamic). From the simulation results of 12 it's models we know the average thrust increase is as large as 47%. © 2021, Royal Institution of Naval Architects. All rights reserved.
