Folding tidal turbine as an innovative concept toward the new era of turbines

摘要: Abstract Research and development of tidal current turbines has undergone significant growth since the past decades. The trials errors have led to improvements for various aspects turbines. One remaining problems is difficulties in transportation installation. concept folding turbine was proposed provide a solution ease installation 2010. Folding foldable parts blades, shaft, connecting rods outer box compared rigid structure conventional turbine. study discusses components turbine, rigidity structure, performance, working concept, efficiency, material, electrical aspects, environmental impacts prevention marine corrosion. Previous works costs were 30% total cost. estimated reduce 20% cost with shorter time.
