The development of a novel 3D inverse design method for turbomachinery aerodynamic design at UCL has led to important design breakthroughs for pump and compressor applications. The resulting IP and software has been commercialised by a UCL spinout company Advanced Design Technology Ltd (ADT), which is now considered a global leader in advanced turbomachinery design software. Since 2008, the 3D inverse design codes embedded within ADT's TURBOdesign™ suite of software have been adopted by many of the leading turbomachinery equipment manufacturers in Europe, Japan and the US. These companies are using the TURBOdesign suite to achieve significant improvements in the time taken to design their turbomachinery components. It has also helped them unlock major efficiency gains and hence achieve a reduction in CO2 emissions. [text removed for publication]
Research in the University of Cambridge Department of Engineering (DoEng) between 2003 and 2010 investigated the technical feasibility and efficiency benefits of an innovative design for the S-shaped ducts linking the two compressors in a modern civil aero engine. Rolls-Royce incorporated this technology in its latest generation of engines (Trent XWB); the benefits in terms of increased fuel efficiency which the new design of S-duct brings are a significant selling-point for what is marketed as "the world's most efficient engine". As at 31 July 2013 Rolls-Royce has an order book of more than 1400 such engines (worth, at list price, approximately GBP 20 billion), of which 832 orders were received within the assessment period.
Cost savings in the order of £130M over the REF period have been achieved by Rolls-Royce through the improvement of engine reliability of civil and military aero-engines, industrial machines used for electricity generation and gas/oil pumping applications through the use of techniques and processes developed by the Vibration University Technology Centre (UTC) at Imperial College London.
Research from the Sheffield Department of Mechanical Engineering has led to major improvements in engineering analysis and design software for aerospace companies such as Rolls-Royce and Airbus. As a result of introducing new practices based on our research, the organisations have reported significantly reduced time input to design components as well as related economic benefits. For example: Rolls-Royce has reported an order of magnitude improvement in the time needed to mesh components. Similarly, by adopting our highly efficient computational aerodynamics solvers, Defence Science & Technology Laboratory has reduced the time its engineers spent evaluating concepts from many days to a few hours.
Research carried out at the University of Southampton has enabled major players in the aerospace industry — among them Rolls-Royce, Airbus, and Boeing — to produce more fuel efficient, longer lasting engines and aircraft at reduced cost. The research has provided the aerospace industry with modelling tools and software enabling companies to explore complex new designs quickly whilst managing product risk in a competitive market. The research team has also developed new design processes for unmanned aircraft, which — as a result of strong media interest - improved public understanding of such new technologies through worldwide coverage. A spin-out company has achieved strong technological and economic impacts in its own right.
Compressors developed at the Department of Engineering Science have formed a key component of the cryocoolers used to cool the infra-red sensors on satellites. Their low mass has trimmed almost $250k from the cost of individual satellite missions. Sixty seven have been sold to date, with sales totalling £2.8M between January 2008 and July 2013; three units are currently in Earth orbit with another nine planned to follow in 2014. A specialised version has been developed to achieve extremely low temperatures, with prototypes already built for the Mid Infra-Red Instrument (MIRI) that will form part of the James Webb Space Telescope.
University of Huddersfield research into the optimal design of flow-handling systems has been credited with "transforming" the development strategies and global market sales of an industrial partner. Weir Valves and Control Ltd has enjoyed a 75% saving in design lead time and a 1,800% increase in annual sales - from several thousand before its collaboration to millions in 2013 - through the structured integration of researchers' computational fluid dynamics expertise in its design process. The success of this collaboration, which has been described as an exemplar of a Knowledge Transfer Partnership, has also led to further research contracts.
Rolls-Royce uses the HYDRA computational fluid dynamics (CFD) code for the design of all of its new gas turbine engines. The HYDRA CFD package, including the mathematical theory behind it, was developed by Professor Mike Giles and his research team in the period 1998-2004 at the University of Oxford, and subsequently transferred to Rolls-Royce, forming the basis of the RR corporate CFD strategy with an investment of over 100 person years in development.
Since 2009, HYDRA has become the standard aerodynamic design tool across Rolls-Royce, and has been used to design Rolls-Royce's Trent 1000 engine and the newer Trent XWB. HYDRA has enabled Rolls-Royce to save over [text removed for publication] in test rig expenses, provides superior accuracy compared to its competitors such as FLUENT, and has contributed to increases in engine efficiency of up to [text removed for publication], which in turn has led to higher sales and increased revenue for Rolls-Royce.
A unified design methodology for tuning gas turbine engine controllers, developed by researchers in the Department of Automatic Control and Systems Engineering (ACSE), is being used by Rolls- Royce across its latest fleet of Civil Aero Trent engines. Trent engines are used to power, for example, Boeing 787 Dreamliner and Airbus A350 aircraft that have been adopted by the world's leading airlines.
This new methodology has made economic impact through the introduction of a new process for tuning gas turbine engine controllers leading to the adoption of a significantly changed technology. Indicators of impact are:
i) a new control law and design practice, resulting in a unified approach for different projects;
ii) reduced development effort by shortening and simplifying the design exercise and rendering it suitable for modular insertion; and
iii) streamlined verification requirements.
This impact is the improvement of aircraft engine efficiency by the application of profiled endwalls to turbine blades. The technology was researched by Durham University and exploited by Rolls-Royce by deploying the technology on airframes. Engines with profiled endwalls include the Trent 900 (A380 airframe), Trent 1000 (787 Airframe) and Trent XWB (A350 airframe). This (as of April 2013) totals around 2000 aircraft engine orders with profiled endwall technology applied. A saving of 1750 litres of fuel per flight from Zurich to Singapore was estimated when profiled endwalls are applied. This gives a 4400 kg reduction in carbon dioxide emissions for such a journey with a fuel cost saving of over $1100. In addition to the environmental benefit and the obvious cash savings for airlines an economic benefit for UK industry has arisen as Rolls-Royce is able to sell engines with a reduced fuel burn as well.
