Digital Twin Concept for Aircraft System Failure Detection and Correction

摘要

The air data system estimates vital flight parameters for correct and safe aircraft operation. One of the main components in this system is the Pitot tube sensor for measuring the total pressure and static pressure to estimate altitude, air speed, vertical speed and Mach number. The Pitot tube can supply incorrect measurement readings when its orifices are blocked by ice, dust or even insects. This paper describes the results of an ongoing research project to develop a solution to aircraft loss of control caused by an unreliable airspeed indication by incorporating the concept of an aircraft digital twin.
