The project involves development of a comprehensive diagnostic system of various parts of Aero Gas Turbine Engine (AGTE), leading to increased operational reliability and longevity of the engine. The system is built on stronger foundation of modern Artificial Intelligence/ Machine Learning (AI/ML) technologies. It efficiently handles large scale data, and conducts operational assessments rapidly with a high degree of accuracy. The Virtual sensor framework, a critical component in the health monitoring of the aero gas turbine, is being developed indigenously. This is a significant step towards developing a digital twin of AGTE.
