预测维护时序包（CMAPSS）
真实开源数据集封装（SKU-05）：NASA C-MAPSS 涡扇发动机退化时序（FD001–FD004）。含 train/test/RUL 多文件；训练表附计算 RUL。交付 package.zip + sample.csv。
提供商： 平台自营
交付形态：文件包
适用场景
1 / 5场景说明
适用于：
1
剩余寿命（RUL）回归基线与特征工程
2
多传感器时序 / 按 unit 滑窗建模教学
3
FD001–FD004 工况与故障模式对比
不适用于：直接替代真实产线预测维护标定数据。
使用指南
2 / 5通过统一 API 拉取数据（全站接口相同，仅替换 slug）。
