| Abstract | The Institute for Ocean Technology specializes in researching and testing models of ships. The Department of National Defence has contracted IOT to develop a stern appendage that will reduce hydrodynamic resistance on the Halifax Class frigate. This appendage will also improve speed and propeller cavitation performance, and reduce the stern wave. The model used for testing contains sensitive electrical equipment which is vulnerable to forces induced by the stern wave impacting the model at the end of high-speed runs. There is also a risk of the stern wave washing over the transom and causing further damage to equipment. Researchers at the Institute have proposed a method to solve these problems through the development of a device called the Wave Suppressor. This device would be used to dissipate the wave energy, and thereby reduce the impact force of the wave on the stern of the model and prevent the stern wave from washing over the transom. This report details the design considerations used in the development of the proposed mechanism and describes its various components. It covers the design criteria that the Wave Suppressor must meet, and how the Wave Suppressor fulfills these requirements. The report first sets the design criteria and then proceeds to describe the Suppressor's connection to the tow tank carriage, the design factors involved in ensuring the wave will be fully suppressed, and the control of the suppressor. It also includes calculations that were used in the design process and provides assembly drawings of the wave suppressor. |
