Evaluation of the durability of composite tidal turbine blades.
The long-term reliability of tidal turbines is critical if these structures are to be cost effective. Optimized design requires a combination of material durability models and structural analyses. Composites are a natural choice for turbine blades, but there are few data available to predict material behaviour under coupled environmental and cycling loading. The present study addresses this pro...
متن کاملPerformance Prediction of a Free Stream Tidal Turbine with Composite Bend-Twist Coupled Blades
Free stream tidal turbines are a source of growing interest in the marine renewable energy field. Some designs that use an actuated mechanism to control individual blade pitch, as the tidal current varies and even during a revolutionary cycle, face the challenge of ensuring high reliability under the loads imposed on the device in the harsh sub sea environment. Adaptive materials have been used...
متن کاملDamping Wind and Wave Loads on a Floating Wind Turbine
Offshore wind energy capitalizes on the higher and less turbulent wind speeds at sea. To enable deployment of wind turbines in deep-water locations, structures are being explored, where wind turbines are placed on a floating platform. This combined structure presents a new control problem, due to the partly unconstrained movement of the platform and ocean wave excitation. If this additional com...
متن کاملDevelopment of High Performance Composite Bend-twist Coupled Blades for a Horizontal Axis Tidal Turbine
An adaptive textile composite, sometimes referred to as a smart material or intelligent material, is a structure tailored to exhibit desirable elastic deformation behaviour not necessarily proportional to the imposed load. An example of such a structure would be a box beam so tailored that an imposed cantilever load results in twisting as well as bending, although no torsional load was imposed,...
