Studies on Structural Health Utility Management System for Transport Aircraft
摘要
The architecture of the Structural Health Utility Management System is studied and presented in this paper. The proposed architecture includes the type of sensors, data acquisition system, structural health monitoring methodologies, and data handling algorithms. In a first step, principal strain angle-based concept is developed using MFC sensors to monitor the event and impact location identification as part of S-HUMS. This technique can be extended to bird impact studies on a more realistic structure, like a leading edge. As part of the proposed architecture, it is planned to measure the strains at critical locations, and the component level damage index will be accordingly estimated. Also, data handling algorithms will be developed to estimate the normalized operational fatigue load spectrum from the quasi-static acceleration loads measured at the aircraft CG. The proposed architecture is adaptable for real-time measurements with new instrumentation or capturing the data from onboard instrumentation and flight data recorders.
