摘要

提出了一种利用光纤光学探头确定飞机发动机旋转叶片到达和离开时间戳的有效算法。这种方法利用光波形的双稳特性来优化状态估计器，计算中层交叉的到达和离开时间。这消除了对耗时的信号处理技术的需要。为了验证该方法，在一台工业风扇和两台不同的发动机上进行了几次台架试验。结果表明，该方法适合于实时实施，在估计叶尖间隙和振动分析定时方面非常有效，计算时间远低于采集时间的40%。

Real-time bilevel algorithm for blade tip clearance and tip timing estimation in aircraft engines

An efficient algorithm is presented for determining the arrival and departure timestamps of rotating blades in aircraft engines using fiber-based optical probes. This approach leverages the bistable characteristics of optical waveforms to optimize a state-level estimator, computing arrival and departure times from mid-level crossings. This eliminates the need for time-consuming signal processing techniques. To validate this method, several bench tests have been conducted on an industrial fan and two different engines. The results demonstrate its suitability for real-time implementation and its effectiveness in estimating blade tip clearance and timing for vibrational analysis, achieving computational times well below 40% of the acquisition times.
