Tidal and wind turbines, due to instabilities in their operating flows, often experience uneven loading. The resulting fatigue, accumulating over the device’s operational life, can lead to component failure, system downtime, and lost revenue. Kuba's work focuses on a system that can effectively reduce loading fluctuations experienced by offshore renewable devices by allowing turbine blades to pitch when experiencing changes in flow passively. His use of numerical tools (blade-element-momentum-theory) paired with experiments demonstrates that low-order models can accurately capture the physics of passive pitch in a hydro-kinetic turbine, serving as a reliable tool for the preliminary design of load mitigation systems. The competitiveness of an adaptive system functional at turbulent and tidal-cycle timescales makes passive pitch a compelling alternative to modern active systems.
