Microstructured Surfaces in Transport and Mobility

Since the invention of the aeroplane, there is a new understanding of mobility. In a short time, freights and persons can be transported over several continents. The aeronautics industry is subject to continued financial pressure. To meet all ambitious future plans regarding CO2 reductionefficiency improvementcost savings and at the same time increased profitability, new innovative technical solutions will have to be realized.

We are experts in the geometrical design of riblet structures to reduce drag and we can specifically design them for any particular aircraft type. This makes it possible to calculate savings in advance – without testing.

By designing the exact Riblet geometry at various operating points, an aerodynamic evaluation is possible using 1:1 3D CFD simulation. This means a maximum increase in efficiency as a result. The evaluation of the advantages of Riblets on different surfaces of the aircraft and the offered profitability calculation help with the trade-off of the respective application. Several simulations have been carried out for both the general aviation and the commercial aviation. 
You can see the hard facts here: 

  • Up to 5% fuel saving and thus a reduction in Co2
  • Significant reduction in noise emissions
  • Cabin noise reduction 
  • Better flight stability in turbulent flight conditions
  • Optimization of the properties of individual components (e.g. wingtips, flaps, engine…)

Rolling stock has a similar importance in transport and mobility as airplanes. Especially high-speed trains get more and more popular. From 2008 to 2012 there was an increase of 60% in the number of high-speed trains worldwide. In the design of the high-speed trains it is a major aim to achieve even higher economic operating speeds. The higher the speed, the higher is the proportion of drag and thus the potential of the use of riblets. First analyses have shown a potential of 5% energy savings at a speed of 300 km/h. Energy efficiency is gained as well as cost reduction in transporting freight and individuals. Furthermore our skilled engineers calculate the riblet geometries with the maximum benefit for your application as well as making a profitability analysis for the use of riblets.

Water is one of the highly productive means of transport, because a high amount of freights can be shipped with little staff and little effort. 90% of the global trade and 95% of the foreign trade of the European Union is carried out on sea. Efficiency is very important for the shipping industry. A very efficient seaborne transportation is achieved through the use of riblets. With the application of riblets on the ship the drag reducing effects of the microstructured surfaces reduce the overall fuel consumption. Furthermore the CO2 emissions are reduced and shipping is made more eco-friendly. All in all costs are cut down and the cost effectiveness is increased.

Autonomous under water vehicles (AUV/UUV) nowadays become more and more important. The unmanned under water vehicles contribute to interesting research programms in geology and biology and help in discovering new areas. The application of riblets results in a lot of advantages in this field of use. Through the microstructured surfaces a drag reduction of 8% is achieved and the energy consumption of the vehicle is lowered. Thereby the operation time is extended and the efficiency is increased about 5%. Moreover several costs are reduced with the use of the shark skin. For the ideal geometric use of the riblets, all active forces are evaluated and the ideal area for the application of riblets is identified. The evalution of the streamlines of the object helps in the right application of the riblets and leads to greater effects.
