The Additively-Manufactured, System-Integrated Tip (AMSIT) project is
leveraging the flexibility of 3D printing to integrate several
technologies in a wind turbine blade tip, while reducing the levelized
cost of electricity (LCOE) produced. The design integration is
demonstrated for a 200 kilowatt-scale turbine with 13-meter blades, with
the outer 15% of the blade replaced with a 3D-printed design.
Aerodynamic performance is enhanced through inclusion of a winglet and
surface texturing, both challenging for traditional manufacturing.
Longevity and durability is improved through integrated lightning and
leading edge erosion protection. Increased power, reduced repair
frequency, and ease of repair through blade modularity all contribute to
reduced LCOE. Cost models are are extended to modern megawatt-scale
designs to estimate the impact of the technology at scale, demonstrating
the potential to reduce LCOE very significantly for modern onshore
turbines, with even higher potential savings offshore.
