Sustainable Hybrid Renewable Energy System
Lightweight, low-cost, durable and environmentally friendly blade for vertical-axis wind turbines.
Wind turbines are subject to torsional loads that can cause deformation, cracks, and fatigue failure. Ting Tan and his team of researchers have addressed this issue by creating a lightweight, low-cost, durable and environmentally friendly blade for vertical-axis wind turbines.
The blade is a composite helicoidal structure composed of a novel honeycombed plastic or fiberglass core covered with laminated bamboo. The core of this design helps reduce or stop traveling stress fractures, and bamboo is known for its resistance to wind erosion.
The end result is a lightweight, thinner, highly aerodynamic blade that minimizes stress and deformations that lead to failure in conventional designs.
