Abstract

A system and methods for real-time model based vehicle structural anomaly detection are disclosed. A real-time measurement corresponding to a location on a vehicle structure during an operation of the vehicle is received, and the real-time measurement is compared to expected operation data for the location to provide a modeling error signal. A statistical significance of the modeling error signal to provide an error significance is calculated, and a persistence of the error significance is determined. A structural anomaly is indicated, if the persistence exceeds a persistence threshold value.

Description

technical field [0001] In general, embodiments of the present disclosure relate to structural anomaly detection. More specifically, embodiments of the present disclosure relate to real-time structural anomaly detection. Background technique [0002] A vehicle or aircraft structure is typically subjected to various external forces throughout its service life: both predictable operational forces and unpredictable forces. The operational health of such structures can be adversely affected by abnormal structural responses to operational and unforeseen forces. Operating forces such as changes in aerodynamic loads and unpredictable forces such as wind gusts can lead to non-optimal structural conditions. Contents of the invention [0003] Systems and methods for real-time model-based vehicle structural anomaly detection are disclosed. Real-time measurements corresponding to locations on the vehicle structure are received during operation of the vehicle and compared to expected...
