Wind tunnel and structural model of the Next Generation Train
Wind tunnel and structural model of the Next Generation Train
The trains of the future need to be efficient, safe and cost-effective. To this end, DLR combines skills in, among other things, aerodynamics, lightweight construction, energy management and communications.
Using wind tunnel models (coloured silver in the illustration), crosswind stability and possibilities for drag optimisation are investigated. A draft design has been prepared (light lattice structure) for the topological optimisation of the train structure, from which conclusions about the main load paths in the carriage body can be drawn. This gives important information for the selection of the manufacturing and assembly technologies to be used for the Next Generation Train.
