Test pilots needed

A nationwide recruitment drive is starting now and will last until mid-2019 to find test pilots who are keen to use a cargo bike model that suits the transport needs in their organisation.

Accompanying research during the test phase

Transportation researchers will accompany the pilot project during the first two years to analyse user acceptance and to estimate its impact on the environment and transport as a whole.

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.

Next Generation Train – 50 percent energy savings in future

At 400 kilometres per hour, a silent double-decker – the Next Generation Train (NGT) – will travel into the future and in doing so will realise energy savings of 50 percent. In this project, the German Aerospace Center (DLR) is combining its skills in the field of railway vehicle research. DLR researchers are working to make the trains of tomorrow lighter, more energy efficient, more comfortable, safer and, at the same time, faster.

One-of-a-kind – the performance of high-speed trains is tested under unprecedentedly realistic conditions in the new tunnel simulation facility at the German Aerospace Center (DLR) in Göttingen.

With this double-deck train model made from carbon-fibre-reinforced composite, DLR researchers measure, among other things, the noise emitted by a high-speed train.

In ‘conversation’ with the traffic lights

Innovative communications and positioning technologies make it possible – cars and transport infrastructure exchange information.

Highly automated: One the touch of a button is enough

With the touch of a button, the driver can select the level of automation. Road traffic accidents are often the result of errors made by inattentive, overstressed or tired drivers. The objective of the EU project HAVEit (Highly Automated Vehicles for Intelligent Transport), in which the German Aerospace Center (Deutsches Zentrum fuer Luft- und Raumfahrt; DLR) played an active role, was to minimise the number of this kind of accidents.

The car of the future

Different DLR vehicle technologies, such as new propulsion concepts or lightweight construction, are evaluated and compared with a computer model. Scientific evaluation makes recommendations for policy and economics.

Schlörwagen flow image

The Schlörwagen was an experimental car, which caused a stir in 1939. It had an amazingly low drag coefficient of 0.186. Measurements carried out in the seventies by Volkswagen confirmed that the drag coefficient of the Schlörwagen was a mere 0.15. Today's passenger cars have a drag coefficient ranging from .24 to 0.3; they cannot match the favourable aerodynamic shape of the Schlörwagen. This image shows a model Schlörwagen in the wind tunnel. The tight airflow is clearly visible.

The free-piston linear generator (FKLG) – a new kind of range extender for electrically powered vehicles

DLR researchers in Stuttgart have become the first team in the world to demonstrate the feasibility of the free-piston linear generator, which they accomplished using a test bench developed specifically for this purpose.

DLR conducts research into the transport sector. With its extensive programme, DLR is Europe’s second largest institutionally funded transport research institution. Here, the challenges for tomorrow's mobility are identified and concrete interdisciplinary solutions are developed. The results contribute to a sustainable transport system in Germany and Europe that benefit both the economy and society.
