Kurzfassung

Aerodynamic measurements – transient surface-pressure and environmental monitoring – have been performed on operational freight-trains in Europe with the DLR FR8-LAB measurement-platform. The FR8-LAB is a self-contained swap-body container, equipped with an on-board power supply – self-charging with solar panels on the roof, data acquisition system and remote-access communication capability that can been transported on normal operating freight-trains. Initial measurements have demonstrated the ability for the on-board systems to function in challenging industrial conditions: remote operation and exposure to vibrations, heat/cold, moisture etc. Surface pressure measurements, as well as LiDAR and thermal imaging have demonstrated the FR8-LAB can be used to characterize the aerodynamic conditions a typical container is exposed to in real-world operation and couple them with the specific operating scenario. Generic, representative conditions that a container on a typical freight-train would experience can be characterized. Further, specific operating scenarios such as: entering/exiting tunnels, travelling over bridges, or passing other rail vehicles - that could exhibit aerodynamic characteristics with increased aerodynamic drag (low operating efficiency) or reduced crosswind stability (potential safety concern) - can be identified and characterized in detail. This work will provide scope and direction for aerodynamic optimization, and validate future numerical and experimental research and development that can aerodynamically optimize freight-trains of the future for improved energy efficiency and safety of operation.
