Framework and Platform for Next Generation Aircraft Health Management System

UTC Aerospace Systems-Ashutosh Kumar Jha, Gaurav Sahay, Adishesha Sivaramasastry
Published 2017-09-19 by SAE International in United States
In aerospace industry, the concept of Integrated Vehicle Health Management (IVHM) has gained momentum and is becoming need of the hour for entire value chain in the industry. The expected benefits of lesser time for maintenance reduced operating cost and ever busy airports are motivating aircraft manufacturers to come up with tools, techniques and technologies to enable advanced diagnostic and prognostic systems in aircrafts.At present, various groups are working on different systems and platforms for health monitoring of an aircraft e.g. SHM (Structural Health Monitoring), PHM (Prognostics Health Monitoring), AHM (Aircraft Health Monitoring), and EHM (Engine Health Monitoring) and so on. However, these approaches are mostly restricted to federated architecture where faults and failures for standalone line replaceable units (LRUs) are logged inside the unit in fault storage area and are retrieved explicitly using maintenance based applications for fault and failure diagnostics. With the transformational growth in computing technology, one can easily visualize the possibilities of moving from present federated architecture to integrated architecture for health monitoring of aircraft in near future.The advanced analytical methods…
