Digital Twin Technology for Gas Turbines

A digital twin is a computer model which mirrors and simulates the operation of an asset or its individual components or a system of assets and their surrounding environment. Digital twin models can also be used for asset life cycle management, anomaly detection and performance optimization. Two types of technologies have emerged for gas turbines; (1) data driven approach and (2) physical model based approach.

In gas turbine industry, data driven approach for engine performance and health monitoring has been around since the 1980s. The generic approach to creating a data driven system is shown below
