Remaining Useful Life digital shadow for an eVTOL Powertrain

This study introduces a real-time digital shadow representation for an electric Vertical Takeoff and Landing (eVTOL) powertrain, aimed at estimating the Remaining Useful Life (RUL) of key components. Leveraging real-time operational data, the digital shadow dynamically updates RUL estimates. The objective of this digital shadow is to enhance the reliability and maintenance strategies for eVTOL systems. The implementation encompasses critical components, including DC link capacitors, the motor, and the battery. Experimental results demonstrate the capability of the digital shadow to adjust RUL estimates in real-time in response to operational condition changes.
