Aircraft Engine Run-to-Failure Dataset under Real Flight Conditions for Prognostics and Diagnostics
International Conference on Data Technologies and Applications, 2021 A key enabler of intelligent maintenance systems is the ability to predict the remaining useful lifetime (RUL) of its components, i.e., prognostics. The development of data-driven prognostics models requires datasets with run-to-failure trajectories ...
