Pathfinder Optics：在风机叶片内部进行无人机检查，每天四台风机
美国公司 Pathfinder Optics 用带保护笼的无人机检查风力机叶片内部。人员不再需要爬进叶片，据称日处理量从1–2台提高到4台。风力机仍须停机，且仍需有人爬到轮毂，100万美元的节省只是笼统估算。
| 业主 | Wind farm operator (not named) |
| 服务商 | Pathfinder Optics |
| 地点 | US West Coast, United States |
| 机型 | Flyability Elios 3 with LiDAR payload |
| 传感器 | visual camera, LiDAR |
引入前
检查员爬到轮毂处，经检修口爬入每片叶片；每天 1–2 台风力机。
引入无人机后
风力机停机后，将无人机带到轮毂处，沿每片叶片内部向下飞行约 220 ft。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| throughput | 4 turbines per day vs 1–2 | 报告值 |
| time per tower | climb, inspection and descent within 3 hours | 报告值 |
| avoided cost | over US$1 million per blade replacement avoided by early detection | 估算 |
注意事项与局限
- Manufacturer case study; owner, site and year not named.
- The $1 million figure is a general claim about blade replacement, not a measured saving.
- Turbines must be shut down; an inspector still climbs to the cramped hub with the drone (or it is winched up).
一天能以多少成本检查多少台风机，是一个路径规划问题，配送研究探讨的是同样的结构。见物流指南的论文卡片On the min-cost traveling salesman problem with drone。
