航空推进系统仿真数据
收藏资源简介:
美国国家航空航天局的商用模块化航空推进仿真系统(CMAPSS)所模拟出的涡扇发动机性能退化数据,包含有风扇、涡轮、压气机等组件参数。数据集可以模拟出从海平面到42千英尺的高度,从0到0.9马赫的速度以及从60到100的油门杆角度。同时在每次循环的某一时间点开始会设置指定故障,并且故障在剩余循环继续存在,从而可以确定故障出现在哪一时刻。该数据集被普遍用作预测涡扇发动机剩余使用寿命预测问题的基准数据集。
Turbofan engine performance degradation data simulated by the National Aeronautics and Space Administration’s Commercial Modular Aero-Propulsion System Simulation (CMAPSS). This dataset incorporates component parameters including fans, turbines, compressors, and other core modules. It supports simulation of operating conditions ranging from sea level to 42,000 feet altitude, 0 to 0.9 Mach speed, and 60 to 100 throttle lever angles. Furthermore, a predefined fault is activated at a specific time point within each operational run, and the fault persists across all remaining cycles, enabling precise determination of the exact timing of fault occurrence. This dataset is widely recognized as a standard benchmark for remaining useful life (RUL) prediction of turbofan engines.
