Chapter 1 Introduction In ewfoundland and Labrador, ocean technology is an important sector with many public and private finns involved in designing new or morc efficient technologies. One of the main components ofmany ofthese developments is the marine propeller. Designing high efficiency and low cost propellers for ships, AUV's, ROV's and other marine applications is therefore a critical research topic. At the same time, the tcchnologies of Computer-Aided Design (CAD) and Computcr-Aid
