It is well known that especially on the top side of open wagons, like hopper wagons, even at low speeds air flows are created that counteract to the forces that accelerate the wagon. Current approaches to enhance the aerodynamic behaviour of wagons are solid closed covers or tarps. But such solutions entail several disadvantages, particularly the complications while loading bulk cargo, but also the disadvantage that the fastening system requires a higher maintenance effort.
To solve the above-mentioned problems, scientists at a German university have developed - in cooperation with a regional company - a hopper wagon that shows big aerodynamic advantages, despite a permanent opening on its top side, and independent from the loading level. The main advantage of this solution is the enhanced aerodynamic efficiency during transport. The novel construction of the wagon functions simultaneously as a strengthening element for the wagon structure. It thereby enlarges the profile of the wagon and reduces its weight. Both aspects finally increase the vehicle’s load capacity. Moreover, the new wagon design protects fine-grained bulk cargo from drifting away, due to the airstream even at low transportation speeds.
This new type of freight car can be used in freight transport, transport, the railway industry or logistics and is more energy-efficient than conventional models due to its aerodynamically advantageous design.
The university is interested in a cooperation in the framework of a license agreement or a research cooperation agreement. A future licensee would have the authorization to use the technology in return for a fee or a share of royalties. The client is also open to agree to a research cooperation agreement that aims at the joint further development of the technology.
