Study, design and manufacture of different propellers as paddle wheel, ducted and torpedo for underwater thrusters applying NC and additive technology

The human being is inquisitive by nature, it is an instinct that drives us to discover the environment that surrounds us, especially those that humanity cannot access, like the ocean, creating the need to implement submersible technologies. This research studies underwater thrusters, as they are one of the main components of submersible technology. The study presents three different thrusters designed in SolidWorks, these are subjected to flow studies, geometry analysis and were manufactured in a 3D printer. Through the different elements that helps prevent water filtration inside the system, the thrusters can operate smoothly underwater. The propeller with the better flow velocity and pressure resistance is made in a pocket NC which is a 5-axis milling machine.
