aerodynamic wind turbine blade model

Design a single aerodynamic wind turbine blade optimized for efficient energy generation. Specifications: Total length: 18 cm Maximum width: 3 cm Gradual taper from root to tip Smooth aerodynamic curvature inspired by airfoil profiles (e.g., NACA airfoil) Slight twist along the blade (angle of attack variation from base to tip) to maximize efficiency Thin trailing edge and rounded leading edge Reinforced root/base for mounting to a small generator hub Lightweight but structurally stable design Technical requirements: Optimize for low wind speed performance Ensure smooth airflow and minimal drag Avoid sharp transitions; maintain continuous curvature Suitable for 3D printing (FDM or resin) with no unnecessary supports Export as solid, watertight STL model Style: Clean, realistic engineering design Functional over decorative Optional improvements: Add subtle internal rib structure for strength (if hollow) Ensure balance for rotational stability
