MTU Friedrichshafen GmbH is a manufacturer of commercial internal combustion engines founded by Wilhelm Maybach and his son Karl Maybach in 1909. Wilhelm Maybach was the technical director of Daimler-Motoren-Gesellschaft - a predecessor company of the German multinational automotive corporation Daimler AG until he left in 1907. On 23 March 1909, he founded the new company, Luftfahrzeug-Motorenbau GmbH , with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH , which originally developed and manufactured diesel and petrol engines for Zeppelins, and then rail cars. The Maybach Mb.IVa was used in aircraft and airships of World War I.The company first built an experimental car in 1919, with the first production model introduced two years later at the Berlin Motor Show. Between 1921 and 1940, the company produced various classic opulent vehicles. The company also continued to build heavy duty diesel engines for marine and rail purposes. During the second world war, Maybach produced the engines for Germany's medium and heavy tanks. The company was renamed MTU Friedrichshafen in the 1960s.MTU derives from Motoren- und Turbinen-Union meaning "Motor and Turbine Union".MTU Friedrichshafen remained a subsidiary of DaimlerChrysler until 2006 when it was sold off to the EQT IV private equity fund, becoming a part of the Tognum Corporation.The company manufactures diesel engines for trains, ships, oil and gas installations, military vehicles, agriculture, mining and construction equipment, as well as diesel generators and very new Molten carbonate fuel cells.In March 2011, it was announced that Rolls-Royce Holdings and Daimler AG were launching a takeover for Tognum. The acquisition of Tognum by the two companies was completed in September 2011.On 9 January 2014, Tognum was renamed Rolls-Royce Power Systems. The decision was made to reflect the industrial ties to Daimler AG and Rolls-Royce Holdings for the large engines, propulsion systems and distributed energy systems. Wikipedia.

With the ULTIMATE project five experienced research groups and four major European engine manufacturers will develop innovative propulsion systems to fulfill the SRIA 2050 key challenges. One of the most challenging targets is the 75% reduction in energy consumption and CO2-emissions. Technologies currently at TRL 3-5, cannot achieve this aim. It is estimated that around a 30% reduction must come from radical innovations now being at lower TRL. Thus, European industry needs synergetic breakthrough technologies for every part of the air transport system, including the airframe, propulsion and power. The ULTIMATE project singles out the major loss sources in a state of the art turbofan (combustor irreversibility, core exhaust heat, bypass exhaust kinetic energy). These are then used to categorize breakthrough technologies (e.g. piston topping, intercooling & exhaust heat exchangers, and advanced propulsor & integration concepts). This classification approach gives a structured way to combine and explore synergies between the technologies in the search for ultralow CO2, NOx and noise emissions. The most promising combinations of radical technologies will then be developed for a short range European and a long range intercontinental advanced tube and wing aircraft. Through the EU projects VITAL, NEWAC, DREAM, LEMCOTEC, E-BREAK and ENOVAL, the ULTIMATE partners have gained the most comprehensive experience in Europe on conception and evaluation of advanced aero engine architectures. Existing tools, knowledge and models will be used to perform optimization and evaluation against the SRIA targets to mature the technologies to TRL 2. Road maps will be set up to outline the steps to develop the technologies into products and bring them onto the market. These road maps will also provide a way forward for future European propulsion and aviation research.


A roller bearing, particularly a needle bearing, for arranging on a pivot pin of a variable guide vane of a turbomachine, is disclosed. The roller bearing includes at least one radially elastic needle which has two opposing end regions and at least one roller region arranged between the end regions and constructed in a cross-sectionally thickened manner. The end regions roll off at associated raceways of a bearing housing of the roller bearing and the roller region is arranged in the region of an associated groove of the bearing housing. A variable guide vane with at least one such roller bearing, a housing of a turbomachine with such a guide vane, as well as a turbomachine, is also disclosed.
