| Abstract | Factorial design is a method of experimental design that can be used to increase the value of multi-factor experiments. The method estimates the effects of the individual factors tested on the overall result to determine which factors most influence the outcome of the experiment. This allows the experimenter to run an additional test series that studies in detail the primary factors while legitimately treating insignificant factors as negligible. Podded propulsors are a relatively recent addition to propulsion options for the shipping industry and are a popular alternative to traditional propulsors with ship designers. The geometry of the pod that encases the motor and shaft of the podded propulsor has been primarily guided by the size of available motors. As motor design becomes more refined and flexible, the relationship of the various parameters (diameter, length, position of strut) with respect to performance becomes a more important design consideration. There are a number of geometric parameters that can be used to optimize the design of the pod and five were chosen for the test series. The results that are presented in this paper are the first set of results obtained from a new pod test apparatus at Memorial University. Numerical results that validate the experimental values are presented. The preliminary results show that some of the design factors are significant at certain J values. |
