WHAT GIVES US IMPETUS - Turbomachinery involves some of the most effective energy converters ever designed by engineers. With a high level of efficiency they are an essential part of the transformation of the energy system and modern air travel wouldn't be possible without them.
IN MOTION – Engineers and scientists have been conducting research into efficient and clean combustion engines since 1956. The responsibility of system suppliers for modern development has grown steadily ever since. The more sophisticated and efficient the engines are, the more important the interaction between the components and the lubricants becomes.
WHAT DRIVES US – The combustion engine has become increasingly more efficient since it was invented. It has thus become the engine that drives the global economy. The focus of engine research, however, is shifting from inventing individual solutions to examining the entire engine – the electrification of the drive system included.
HOW WE DEVELOP – It has been a long time since developers have only used the test bed or actual applications to try out new powertrains. The life of a new combustion engine begins on the computer screen nowadays. All components are calculated and simulated by highly sophisticated programmes long before the first prototype has to prove itself.

The Moving Power of Engine and Turbomachinery Research

The FVV (Forschungsvereinigung Verbrennungskraftmaschinen | Research Association for Combustion Engines ) is a worldwide innovation network of companies, research & technology performers (RTD) and funding bodies. In the context of pre-competitive Industrial Collective Research (IGF), manufacturers of automotive engines, industrial engines and turbomachinery as well as their suppliers and service providers work together with universities and other research establishments on cutting-edge technologies. The aim is to make prime movers - internal combustion engines, hybrids, turbomachines and fuel cells - cleaner, more efficient and sustainable – for the benefit of society, industry and the environment. The FVV has invested more than 500 million euros in 1,200 research projects since it was founded in 1956.

Sharing new ideas to generate innovations

Europe is the world's largest factory of knowledge, ideas and innovation: Around one-third of the global production of know-how and innovative products comes from EU engineers and researchers. Cross-border cooperation unites the best minds and ideas. It makes the difference: globalisation - climate-neutral economy - energy transition in transport - mobility of tomorrow. These are just a few examples of the tasks of the future that need to be adressed - together with our members and partners in Europe and the world.

Impact of Biogenic Fuels on the Fatigue Behavior of Steels

Bioethanol-containing fuels from regenerative sources, such as wheat straw and sugar cane, are used to blend fossil fuels in order to reduce climate-damaging greenhouse gas emissions. The hygroscopic properties of ethanol in such fuels represent new requirements for the materials used in fuel-carrying components with regard to corrosion. Within the framework of a Research Association for Internal Combustion Engines and German Research Foundation-funded research project, the corrosive influence of biogenic fuels on the fatigue behavior of application-relevant steels was investigated in a cooperation of the research group for System Reliability, Adaptive Structures and Machine Acoustics (SAM) as well as the Center of Structural Materials (MPA-IfW) of the Technical University of Darmstadt and the Leibniz Institute for Materials Engineering (IWT) in Bremen.

Mistuning and Damping of Turbine and Compressor Impellers

Turbocharging is known to be a well-established technology for an engine’s efficiency and power output by forcing extra compressed air into the combustion chamber. The centrifugal loads, necessary flow deflections, unsteady pressure fluctuations, and structural temperature gradients put a high strain on rotating components. Additionally, those components are prone to high-cycle fatigue. The Chair of Structural Mechanics and Vehicle Vibrational Technology at the BTU Cottbus-Senftenberg investigated the impact of manufacturing tolerances on the vibrational behavior of several turbine and compressor impellers. Finally, it is shown that intentional mistuning can lead to significantly lower stresses.
