The prompt
From-scratch high-performance mini wind turbine for a Bambu P1P: 400 mm three-blade rotor with twisted NACA 44xx blades sized by Schmitz optimum chord and twist, NEMA 17 stepper as a direct-drive generator, streamlined nacelle with spinner and red beacon, printed 6 mm BB slewing-ring yaw bearing with a slip ring, tail vane, three-section tapered tower clamped by two M8 rods, and a ballast and electronics base holding an 18650 battery, CN3791 MPPT charger and a light-switched 1 W LED.
Parameters
| Name | Value | Range |
|---|---|---|
| Rotor radius (blade tip) | 200 mm | 150 – 200 |
| Design tip speed ratio | 5 | 3 – 7 |
| Design angle of attack | 5 deg | 3 – 8 |
| Design lift coefficient | 0.9 | 0.6 – 1.1 |
| Maximum blade chord (root) | 48 mm | 35 – 60 |
| Tower height (3 sections, keep under 345 so the M8 rods fit) | 340 mm | 240 – 345 |
| Tower diameter at the bottom | 60 mm | 55 – 70 |
| Tower diameter at the top | 46 mm | 46 – 50 |
| Tower wall thickness | 3 mm | 2.4 – 4 |
| Yaw bearing ball diameter (6 mm airsoft BBs) | 6 mm | 5.5 – 6.5 |
| LED body seat diameter (8 mm body) | 8.4 mm | 5 – 14 |
| LED solder tab slot length (15 mm across tabs) | 15.6 mm | 10 – 20 |
