Composite materials with integrated hinge zones – bio-inspired lightweight actuators for panel elements
This bio-inspired lightweight technology makes it possible for the first time to integrate actuators in surface elements made of composite materials and thus open up completely new design possibilities - not only for architecture.
Exhaust tract for combustion engines – turbocharger
The novel MEDUSA technology for turbocharging combustion engines fits the current trend to downsize engines perfectly. The optimal inflow into the turbine, particularly at low speeds of revolution, makes the engine very responsive, with maximum torque developing in the lower range of rotatory speed. Additionally the exhaust tract that forms part of the invention is extremely robust, in particular at high combustion temperatures. Thus the technology is particularly suited for use in small gasoline engines: the efficiency is greater than for wastegate turbochargers; however, unlike the Variable Turbine Geometry (VTG) turbocharger, this charger does not require adjustable guide vanes.
Innovative nozzle design with homogeneous flow profile usable as divergent long-range nozzle with high penetration depth
A novel divergent nozzle design, which provides for a homogeneous flow profile even at long distances from the nozzle exit, was developed at the University of Stuttgart. The flow profile is optimized by a central body, shaped and placed in the flow channel in such a manner as to achieve a uniform flow and temperature distribution at the target object. Based on these characteristics, the invention is particularly suited to be used as a long range nozzle for large penetration distances in drying and ventilation applications.
Lightweight design for multilayer composites with damping properties
The newly developed sheet metal composite material can be used for a wide range of applications in the automotive sector as well as in the field of mechanical engineering and manufacturing of deep-drawn part. In relation to its weight, the material possesses a high level of rigidity which can be adjusted to meet specific requirements.
The new hybrid material consists of two individual panels bonded via a viscoelastic layer, which has damping properties. Because the material has one plane outer surface paint finish can be applied and flow properties can be enhanced by adding nanostructures, for example.
Correction of angular errors in optical encoder readings prior to sensor signal generation
The purely optical compensation of errors in encoder readings allows for robust sensor design with alignment-free assembly of the encoder disc. Due to a diffractive compensation track the beam spot on the measuring track can be compensated prior to sensor signal generation.
