The consultancy company AeroTex makes use of UCL research findings to design new and improved ice protection systems for fixed wing or rotor aircraft. These new designs enable AeroTex's customers (aircraft manufacturers and Tier 1 equipment suppliers) to comply with upcoming changes that are raising aircraft certification standards and to operate aircraft more safely in icing conditions. The increase in income to AeroTex resulting from this work was approximately [text removed for publication] per year between 2010 and 2013, representing around 15% of AeroTex's annual turnover.
Aircraft icing is a significant factor in many aircraft accidents and incidents. Ice accretion on the wings has adverse aerodynamic effects, such as loss of lift and control, and ice can also block inlets into key flight sensors. Work by Richard Purvis and his Research Associate, Peter Hicks at UEA, in collaboration with AeroTex UK and QinetiQ, led to better understanding of how the impacts and splashing of water droplets influence the ice that forms on aircraft wings. This led to improved computer prediction codes, which are used by industry to improve design and help satisfy certification requirements.
As a direct result of University of Glasgow research, there have been no deaths in a gyroplane accident in the UK since 2009. Previously, gyroplanes (also known as autogyros) had a questionable safety record. Following fifteen years of comprehensive studies, researchers recommended innovative new design standards to the Civil Aviation Authority. These recommendations led to the introduction of new civil airworthiness requirements in the UK, subsequently adopted by Australia and Canada. The implementation of these revised regulations has forced gyroplane manufacturers to change their designs. Close to 2000 machines have been produced since this design change, revolutionising gyroplane safety worldwide.
Evaluating the ground-based manoeuvrability of large aircraft is time consuming and costly if explored though industry-developed complete models of ground dynamics. Research by Krauskopf and colleagues from the University of Bristol has shown that applying methods from dynamical systems allow these dynamics to be investigated efficiently and with considerable precision. This approach, and the related purpose-developed software, Dynamical Systems Toolbox, have been adopted by Airbus. It is now fully incorporated in the Airbus Methods and Tools portfolio as a supported tool for the evaluation of proposed works and new designs. The research delivers considerable savings in time and costs for the company. Additionally, this programme of research has delivered research training for Airbus employees and one, who studied for PhD with Krauskopf, now leads the Airbus development and implementation of these mathematical techniques which are being disseminated more widely within the company. There continue to be Bristol EPSRC CASE PhD studentships in collaboration with Airbus co-supervised by Krauskopf (7 in the assessment period).
Runway stones thrown up by aircraft undercarriage wheels can cause considerable damage to the aircraft structure. A model of runway debris lofting developed at Imperial College has been used for the new A400M military transport aircraft, which Airbus reported was `absolutely needed' during the successful development of a nose wheel debris deflector [5. A]. This deflector dramatically reduces the incidence and severity of the runway debris impacts and the associated maintenance costs and downtime of the new aircraft. Airbus has received 174 orders to date for the A400M. An indication of the cost savings comes from the Hercules C130K, the predecessor of the A400M, which incurred costs of up to £1M for each aircraft on active service in Afghanistan for the repair of runway debris damage. This cost is now eliminated for the Airbus A400M aircraft.
In the 1990s Dr D Moore, who has extensive experience in fluid dynamics, worked with collaborators at the US Naval Research Laboratory (NRL) on parallelising an ocean modelling code. This resulted in the Navy Layered Ocean Model (NLOM) and later the Hybrid Coordinate Ocean Model (HYCOM). NLOM and HYCOM, which were/are distributed through the NRL and HYCOM consortium, are open access ocean modelling codes that are used to forecast ocean currents. They have proved particularly impactful for the forecasting of ocean oil spills and the corresponding management of the environmental risk. NLOM and/or HYCOM have been used extensively in the Deepwater Horizon oil spill in 2010 as well as the Montara Well Release oil spill in Australia in 2009, providing valuable forecasts to assist with the response to the disasters.
As research led by Professor Martin Siegert at the University of Bristol between 2001 and 2006 has shown, a complex, dynamic and living world exists beneath the thick ice sheets of Antarctica. These pristine aquatic environments are likely to be subject to international exploration and study for decades to come. Siegert and his team not only furthered scientific understanding of subglacial lake systems but also highlighted the potential damage to these environments during direct exploration and demonstrated the need for a formal code of conduct to protect them from contamination or undue disturbance during such work. The research was instrumental in achieving the adoption by the Antarctic Treaty Consultative Meeting in 2011 of a code of conduct presented by the Scientific Committee on Antarctic Research. The code, which is binding on the 50 nations that are signatories to the Treaty, identifies subglacial environments as being of special scientific interest and provides clear guidance to scientists on accessing these fragile ecosystems responsibly. Prior to this agreement, given that traditional deep-ice drilling techniques involve kerosene-based antifreezes, the ecosystems within subglacial lakes and their downstream catchments were in danger of being seriously compromised.
As a consequence of his research on subglacial lakes and in recognition of the impact of his work, Siegert was awarded the 2013 Martha T. Muse Prize by the Tinker Foundation (value $100,000).
Our flow modelling and process optimisation research has improved significantly the scientific understanding of key industrial coating, printing and droplet flow systems. We have implemented our research findings in software tools for staff training and process optimisation which have enabled: (i) the worldwide coating industry to improve the productivity and sustainability of their manufacturing processes; (ii) [text removed for publication]; (iii) a major automotive supply company to develop an award-winning droplet filtration system for diesel engines.

This case study details the impact of current glaciological research at the University of Aberdeen on the Earth's polar ice sheets on practitioners and services in the non-academic science community, specifically the British Antarctic Survey (BAS) and European Space Agency (ESA). In addition, the research has informed public understanding of the stability of the polar ice caps under the influence of climate change. The beneficiaries of our research are professional scientists in Environmental and Earth Sciences working at BAS and ESA who have used our findings to constrain computer modelling of ice sheet dynamics and to calibrate and validate measurements of ice sheet mass change. We have been involved in major international collaborative field research on the Antarctic and Greenland Ice Sheets to better define the current basal and surface boundaries of the ice sheets and to improve the understanding of the sensitivity of the ice sheets' boundaries to climate change over a range of timescales.
NASA's Cassini mission to Saturn's icy moon Enceladus in 2009-10 investigated the presence of explosive ice geysers towering over the south pole of the planet. The geysers consist of vapour and ice particles which rise up to 1,000 kilometres above Enceladus' surface. The source of these jets has been hotly contested. Cassini's mission was to fly as close as possible to the plumes to search for evidence of sub-surface water containing the building blocks of life.
Mathematical modelling, conducted at Leicester, allowed the mission designers to calculate the possibility of the Cassini Spacecraft colliding with dust from the Enceladus jets, with potentially catastrophic results, enabling the craft to be manoeuvred as close as safely possible to the moon's surface to capture the images it required.
The mission, with an estimated $3.26 billion cost, was successful — gathering evidence that the research team's hypothesis of a subterranean sea on Enceladus was correct — a revelation which has inspired public interest around the world.
