Abstract
The digital twins storage and application service hub, in short twinstash, is a software system aiming to provide a basis for Digital Twins of DLR research aircraft. Initialized in the context of the DigTwin project and its successor project DigECAT, its current stable prototype supports the upload, download, and search for flight sensor data and metadata both programmatically via python and graphically via a browser-based user interface. The latter additionally allows to quickly and intuitively navigate through the data. It provides rich possibilities to visualize and filter flight trajectories as well as sensor data. In this paper, we give an in-depth view on the twinstash software system. We provide details on its architecture, continuous integration and deployment, authentication mechanisms, data model, search, main features of its graphical user interface, and its python client
