Rim-Driven Thrusters are emerging as a viable replacement for conventional propulsion systems due to the forecasted advantages that include a simplified powertrain system, reduced complexity, as well as eliminates the need for thru-hull penetration of the shaft. However, large-scaled commercial solutions exist of rim-driven thrusters, the availability of such systems for the propulsion of model ships are found to be absent from the open-source knowledge domain. This knowledge gap motivated the investigation reported herein, which focuses on the design, integration, and testing of a steerable rim-driven thruster for the Short Takeoff Aviation Support Ship (STASS) model. Due to the time and resource limitations, an off-the-shelf design approach was adopted. The finalized system included a Hydromea rim-driven thruster connected to a steering mechanism through a vertical steering column. An open-loop control system was developed in the LabView-2014 to facilitate the control and data acquisition through the same interface. Except for the thruster and the steering stepper motor, the in-house designed system used additive manufacturing techniques to fabricate components and structures used in model testing. This allowed a more rapid transfer of design details from the development site to the manufacturing, integration and testing facility. The designed Steerable Hub-less Integrated Propulsion System (SHIPS) was integrated onto previously optimized STASS model and tested in the 140-foot tow basin under varying Froude numbers. The testing matrix consisted of four configurations to assess the effect of the newly designed and integrated system on the drag force observed. These model configurations include bare hull, appended with SHIPS, bollard pull, and self-powered phases. The drag force was found to increase by 20% after integration of the motor cage for SHIPS due to the increased wetted surface area and the blockage effect induced by the presence of the motor-cage and steering column normal to the flow direction. Further increase in drag force was reported after the integration of the thruster. Nonetheless, the power of the selected thruster was able to propel the STASS model up to a speed of 1.78 knots. Overall, the reported results demonstrate the technical feasibility of SHIPS to efficiently propel model ships for basin testing.
