A Software Framework for IVHM Based on Fault Injection across Various Subsystems

2011-2014

This project aims to develop software platform for simulating faults in aircraft systems with a focus on airframe structure and associated primary structural subsystems. Flight load data is modeled by incorporating six-degrees of freedom model of aircraft. Flight load estimation schemes allow load transfer on structural components for finite element analysis by integrating various standard software tools. Fatigue and damage analysis is performed on finite element representation and also by extracting reduced-order model of the full system description. Landing gear and engine subsystems as specific cases are modeled with reduced order modeling techniques and various diagnostics and prognostics tasks are simulated. The framework and the process can be specialized to applications where that actual sensor data are to be used along with simulation data to perform root cause analysis, timing based prediction of future events.
