Rolls-Royce in Germany has a significant involvement in German and European technology programmes to develop even more environmentally friendly engines.
Rolls-Royce continues to invest in core technologies, products, people and capabilities with the aim of broadening and strengthening its product and service portfolio, improving efficiency and enhancing the environmental performance of its products.
Sixty per cent of research and development investment and 40 per cent of new product development spending over the past five years has been outside the UK. Research and development are carried out at facilities in the UK, Germany, Italy, Singapore, Japan, the USA and Scandinavia. Relationships with the 28 universities where there are Rolls-Royce University Technology Centres are particularly strong.
Over the past ten years Rolls-Royce has invested £7.5bn in research and development. In 2011 alone we invested £908 million in R&D. Globally the company employs over 11,000 engineers approaching 30 per cent of the total workforce.
Rolls-Royce has significant involvement in both German and European technology programmes to develop even more environmentally friendly engines.
Rolls-Royce cooperates with numerous German research institutions, such as universities and the GermanAerospace Research Establishment (DLR). Brandenburg University of Technology (BTU) at Cottbus, the Technical University of Dresden, the Technical University of Darmstadt and Karlsruhe University have already joined the Rolls-Royce University Technology Centre (UTC) network. The UTCs operate on a long-term, funded basis, which ensures continuity of research work.
The following is a small selection of the projects which Rolls-Royce is currently working on in Germany;
Engines with counter-rotating propellers (Open Rotor) have the prospect of reducing CO2 reductions by approximately 25% or more in short-haul and medium-haul operations, compared with current production engines. Considerable technological effort will be necessary to achieve the potential of the Open Rotor. Rolls-Royce is taking up these challenges by initiating an engine technology programme.
Only through lean combustion technology will it be possible to significantly reduce the NOx emissions of future aero engines. To do this it is necessary to surmount problems inherent in lean combustion, such as the propensity for thermoacoustic vibration and reduced combustion efficiency in the partial-load range.
