| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Wind Turbine Blade 7 parts | 3× | Long composite aerofoil that captures wind energy on a turbine rotor. Two fiberglass shells bonded over internal spar caps and shear webs form a hollow beam that twists from a thick circular root to a thin tip, transferring aerodynamic load into the hub through a bolted root joint. |
| 2 | Cast Hub | 1× | |
| 3 | Spinner (Nose Cone) | 1× | |
| 4 | Wind Turbine Pitch System 6 parts | 3× | One per blade |
