项目摘要

Instream Energy Systems Corp. is a Canadian based company active in the field of hydrokinetic systems for tidal streams and inland applications. Given the minimal environmental impact, the use of hydrokinetic systems has become an attractive alternative to small and midsize internal combustion power generators. The company's vertical axis hydrokinetic turbines convert the kinetic energy of flowing water into electricity in a sustainable fashion. In this project the feasibility of replacing a stainless steel rotor shaft in a hydrokinetic turbine with a fiber reinforced polymer composite (FRPC) shaft will be examined. In the industrial partner's current hydrokinetic turbine design, stainless steel is used for the vertical turbine rotor shaft, which is cantilevered from the top end where it attaches to the above-water generator system. The shaft carries the turbine blades, all of which are immersed in the water flow. Drawbacks associated with this arrangement include high material and manufacturing costs and the heavy weight of the system. In the proposed study, the university researchers will contribute their expertise in design, simulation and modeling of cost-effective and lightweight FRPC components toward an improved shaft design for the hydrokinetic turbine. To investigate design solutions, existing FRPC shaft technologies will be researched and analyzed to assess capabilities and future research needs for the target applications. Technical specifications will be developed by investigating the existing hydrokinetic turbine shaft and comparable FRPC structures, e.g. FRPC drive shafts for industrial and transportation equipment as well as wind turbine systems. The industrial partner is instrumental in this process due to their perspective and expertise in the field of designing and developing hydrokinetic power generation systems. By combining the expertise and capabilities of the industrial partner and the university researchers an expert team is thus created enabling effective and timely research. Following the engagement phase, it is anticipated that future collaborative work will lead to detailed research toward an optimized design and prototype development for a suitable FRPC shaft solution.
