According to the abstract released by the Intellectual Property India: "This innovative Boron Carbide (reinforced) Morphing Wind Turbine Blade is intended to provide maximum aerodynamic efficiency and durability in varying wind conditions. The conventional wind turbine blades have fixed shapes that restrict the performance in varying wind conditions. The present invention overcomes the shortcomings of the conventional wind turbine blades by incorporating the Morphing Wind Turbine Blade with an advanced material system. The material system is formulated with a combination of glass fiber-reinforced epoxy with boron carbide particles ranging between 1-5%. The material system is prepared using the precision hand lay-up method. The material system is found to enhance the tensile strength, bending stiffness, and surface hardness of the blade while providing the required flexibility using the material composition. The material composition is found to be optimal at 3% concentration with the required rigidity and ductility. The Morphing Wind Turbine Blade is provided with the required functionality using the camber twist mechanism. The morphing mechanism uses camber and twist variations to adapt the blade's geometry in real time. Computational Fluid Dynamics (CFD) simulations conducted demonstrate that this adaptive profile improves the lift-to-drag ratio, delays the onset of aerodynamic stall, and reduces wake intensity. Furthermore, the reinforcement offers superior fatigue life and wear resistance, protecting the blade against environmental degradation. This synergy of smart structural adaptation and advanced material science provides a scalable framework for next-generation wind energy systems, resulting in higher power coefficients and extended operational lifespans compared to conventional fixed-geometry blades."
