Networked aero-engine control faces delay/packet loss, yielding non-Gaussian time-varying noise that degrades Gaussian-based diagnosis. We build an augmented fault-propagation model and propose an adaptive minimum-entropy UKF detector plus a reduced-order filter for node isolation/estimation. At 75% loss: >98% detection, >99% isolation, ~99.8% estimation.
