Towards Digital Twins for Research Aircraft of the German Aerospace Center#
Michael Baessler (DLR)
Abstract#
The German Aerospace Center (DLR) operates a fleet of thirteen research aircraft which record many thousand parameters within each flight. To make this valuable and constantly growing data source available to scientists and being able to analyze it efficiently requires a tailored solution. The digital twin storage and application service hub (twinstash) is a software system developed within the DLR to address this topic. It supports the upload, download, and search for flight sensor data both programmatically via python and graphically via a browser-based user interface. The web GUI additionally allows to quickly and intuitively navigate through and inspect the content. It provides possibilities to visualize and compare flight trajectories as well as recorded parameters. Besides the actual flight data, a variety of additional information such as project documents, 3D-scans, 3D-models, components, measurement system configurations along with simulations have to be stored adequately within the scope of a digital twin with hierarchical and time references. This talk will summarize the use case, describe the system architecture, show current capabilities and provide an outlook on future developments.
