Design, analyse and manufacture propeller blade for remotely underwater vehicle

摘要

This thesis contains details on the designing a propeller for the Remotely Underwater Vehicle. Remote Operated Vehicles (ROV) is a technology which is frequently used to service the military, ocean engineering activities and also commercial activities such as oil and gas industry. Propulsion plays a significant role in the manoeuvrability of the ROV. The objective of this paper is to conduct simulation studies to design and modelling the ROV propeller blade, and then manufacture the prototype by using Fused Deposition Modeling machine. OpenProp, an open-sourcedprogram developed at Massachusetts Institute of Technology is used to design the propeller and analyse the on-design performance of it. It is found that there is a deviation of 14% to 19% on the experimental results compared to the theoretical results. This might cause by wall effects that occurs on the tank, and surface roughness and blunt trailing edge of the blade prototype. In conclusion, improvement on the experimental setup is needed in order to obtain a much accurate results.
