Components built using 3D composite manufacturing methods developed by Cranfield are now flying on the Boeing 787 Dreamliner aircraft. This is the first use of structural composites in commercial aircraft landing gear. The prototypes were assembled and reinforced using robot automated technology developed at Cranfield.
Cranfield's work has extended the use of composite materials into critical landing-gear systems, allowing Messier-Bugatti-Dowty to contribute to the use of 50% composite materials for the airframe of the new 787, delivering weight reduction and better fuel economy.
The automotive and aerospace industries are keen to reduce their environmental impact and so have looked to move to lightweight materials. This creates issues in terms of joining, using and disposing of dissimilar materials. Oxford Brookes has therefore worked with national and multi-national companies in the adhesive, materials, automotive and aerospace industries to try to solve these problems. This has resulted in high quality research publications, innovative test equipment, improved numerical methods, novel designs, design guidelines, manufacturing procedures, British Standards, patents, commercial products and further funding. The impact of the work has global safety, environmental and economic benefits with multi-national aerospace and automotive companies implementing the results in current developments.
Following the North Sea Piper Alpha oil rig accident in 1988 and subsequent Cullen inquiry, new and safer maintenance procedures were introduced. One of the most significant changes was the restriction in the use of welding repairs (hot work) in the maintenance of plant and pipework due to the risk of fire and explosion. Research at Newcastle provided a novel engineering model that formed the basis for implementation of a new repair technology. This used fibre reinforced polymer wraps to restore the integrity of pipes without `hot work' or any interruption of production, thus minimising operational costs and increasing worker safety. This new technology has now become industry standard with new ISO and ASME standards for pipeline repair established as mandatory standards in 2006 and 2008 respectively (ISO/TS 24817 — Composite repairs for pipework; and ASME PCC-2, Repair of pressure vessels and piping). The period 2008-2013 has seen considerable expansion, worldwide, of an industry offering materials and support services to enable composite repairs to be designed and carried out.
For aerospace vehicles, the development of new materials and structural configurations are key tools in the relentless drive to reduce weight and increase performance (in terms of, for example, speed and flight characteristics). The economic drivers are clear — it is widely recognised that it is worth approximately $10k to save one pound of weight in a spacecraft per launch and $500 per pound for an aircraft over its lifetime. The environmental drivers (ACARE 2050) are also clear — reduced aircraft weight leads to lower fuel burn and, in turn, to lower CO2 and NOx emissions. With such high cost-to-weight ratios, there is intense industrial interest in the development of new structural configurations/concepts and enhanced structural models that allow better use of existing or new materials. Analytical structural mechanics models of novel anisotropic structures, developed at the University's Advanced Composites Centre for Innovation and Science (ACCIS), are now used in the industrial design of aircraft and spacecraft. Based on this research, a new, unique anisotropic composite blade, designed to meet an Urgent Operational Requirement for the MoD, is now flying on AgustaWestland EH101 helicopters that are deployed in Theatre. In addition, the new modelling tools and techniques have been adopted by Airbus, AgustaWestland, Cassidian and NASA and incorporated into LUSAS's finite element analysis software. These tools have, for example, been used to inform Airbus's decision to use a largely aluminium wing design rather than a hybrid CFRP/aluminium wing for the A380.
Research into vibration damping has had a major economic and operational impact on Rolls- Royce resulting in a new design for [text removed for publication] engines used on [text removed for publication] wide body airliners. This has saved [text removed for publication] engine refit costs. The team has also designed a particle damper to reduce vibrations and significantly increase the life of the fuel system [text removed for publication].
Dr Richard Brooks and his team at the University of Nottingham have been investigating the high strain rate behaviour of composite materials since 2003. This has led to the development of two products that are being installed in streets in the UK and Ireland by East Midlands SME Frangible Safety Posts Ltd. The direct benefits to the company have been: the installation of 900 products in the UK and Ireland; saving of £17k capital cost and 2 months in terms of time to market per product developed and; raising of £1.8M investment to bring the products to market At least one life has already been saved in the Shetland Islands as a direct consequence of the product behaving in the way it was designed to.
A significant body of research in ultrasonics at the University of Strathclyde led to the formation of Alba Ultrasound Limited in 2000. This successful UK engineering manufacturing company designs and manufactures high quality wideband ultrasonic array transducers for sonar applications to a worldwide client base, delivering benefits ranging from naval and maritime security through to safer ocean environments and informed exploitation of marine resources. Alba Ultrasound's unique array transducers constitute the sensor front-end in many leading sonar systems, and its innovative products are incorporated in a range of sonar devices used by the military and commercial companies. Through application of Strathclyde research, the company has experienced a significant period of growth during 2008-2013, with a three-fold increase in employees and turnover rising from £750k to £3.8M.
Research into a number of different aspects of rubber has fed into a series of extremely successful collaborations between Queen Mary and a large number of industrial partners. This has led to significant economic impacts, ranging from enhancing the performance of teams in the multi-billion dollar sport of Formula 1 Racing, to helping develop new UK designed and manufactured radial tyres for large civil aircraft. Rubber research has been undertaken continuously at QMUL for over five decades. Prof. James Busfield has led the activity since 1994, working with more than 30 major industrial collaborators, including Bridgestone, Dunlop, Red Bull Racing F1 and TARRC, who have applied our research and employed our researchers to achieve commercial and competitive advantage.
Research at University of Cambridge Department of Engineering (DoEng) has created a new fundamental understanding of the static, dynamic and blast performance of lattice sandwich structures (a repeating pattern of metal struts between two sheets of metal). Ship builders in the Netherlands and the USA have built over 19 ships worth approximately GB200M using this technology since 1/1/2008 with many more planned. These ships are:
Research carried out by Prof. Ton Peijs and colleagues has led to significant breakthroughs in engineering plastics: PURE® and its licensed Tegris® technology, which are lightweight self- reinforced alternatives to traditional polypropylene (PP) composites such as glass-fibre or natural- fibre-reinforced PP. Environmentally friendly and 100% recyclable, these strong and ultra-light self- reinforced plastics have been successfully used across a number of applications, from suitcases and sports gear to protective armour and automotive panels, with impressive results. When used for car, truck and van components, they have been shown to help lower exhaust emission levels and increase fuel economy.
