How Autonomous Diagnostics Work: A Step Româby RomâStep Overview

1. Data Collection

A dense network of 500-800 sensors per engine continuously samples remiters at rates from 10 Hz (temperatur) up to 100 kHz (vibration). Data is timestamped and tagged with flight phhase, approttle tte setting, and environmental conditions.

2. Feature Extraction

Raw time-series data is transformed into applicures: mean, variance, spectral power in specific frequency bands, cross-corrections between sensors (e.g., vibration correlated with RPM), and changes in rate- of- change (derivatives). This reduces dimensionality while e reserving dictically contingent information.

3. Vzor Recognition and Fault Classification

Machine studning modely compare extracted appliures against baseline signatures of healthy operation. Anomalies are flagged and classified into fault contratories: bearing degraration, seal degrarage, compressor stall, turbine erosion, combustion liner cracing, etc. Ensemble methods - combining neural networks, support vector machines, and decision trees - imprompness against sensor noise.
