Advanced turbulence simulation for aerodynamic application challenges (ATAAC)

The ATAAC project aims at improvements to Computational Fluid Dynamics (CFD) methods for aerodynamic flows used in today's aeronautical industry. The accuracy of these is limited by insufficient capabilities of the turbulence modelling / simulation approaches available, especially at the high Reynolds numbers typical of real-life flows. As LES will not be affordable for such flows in the next 4 decades, ATAAC focuses on approaches below the LES level, namely Differential Reynolds Stress Models (DRSM), advanced Unsteady RANS models (URANS), including Scale-Adaptive Simulation (SAS), Wall-Modelled LES, and different hybrid RANS-LES coupling schemes, including the latest versions of DES and Embedded LES. The resources of the project will be concentrated exclusively on flows for which the current models fail to provide sufficient accuracy, e.g. in stalled flows, high lift applications, swirling flows (delta wings, trailing vortices), buffet etc. The assessment and improvement process will follow thoroughly conceived roadmaps linking practical goals with corresponding industrial application challenges and with modelling/simulation issues through stepping stones represented by appropriate generic test cases. The final goals of ATAAC are: - to recommend one or at most two best DRSM for conventional RANS and URANS- to provide a small set of hybrid RANS-LES and SAS methods that can be used as reference turbulence-resolving approaches in future CFD design tools - to formulate clear indications of areas of applicability and uncertainty of the proposed approaches for aerodynamic applications in industrial CFD - Contributing to reliable industrial CFD tools, ATAAC will have a direct impact on the predictive capabilities in design and optimisation, and directly contribute to the development of Greener Aircraft.

Holistic and sustainable abatement of noise by optimized combinations of natural and artificial means (HOSANNA)

Objective: Noise pollution is a major environmental problem within the EU. The social costs of traffic noise have been estimated to 0.4Prozent of total GDP. Road traffic is the dominant source, and also rail traffic noise is significant. At the same time, road and rail traffic are expected to steadily increase, and the source strength is not expected to significantly decrease within the near future. To reduce the outdoor traffic noise to a sufficiently low level for a good acoustic environment is a major challenge of high need. Here, we will focus on noise propagation abatement for the outdoor environment. Following the EU Directive on environmental noise, a series of major action have been taken in noise abatement, but the sustainability has rarely been paid attention. The main idea of our project is to optimize the use of green areas, green surfaces and other natural elements in combination with artificial elements in urban and rural environments for reducing the noise impact of road and rail traffic. The project offers a variety of powerful abatement strategies that will make a cost effective improvement by its combination of approaches concerning: ground and road surface treatments; trees, forests and tall vegetation; greening of buildings and other surfaces; and innovative barriers. The noise impact will be assessed in terms of sound levels (including spectra and time patterns) as well as perceived environment (including annoyance, well-being and other health related aspects). The main objectives of the project are: to show by full scale evaluation that the proposed abatement methods work; to deliver noise prediction methods applicable to the proposed abatements, which can also can be used in noise mapping software; to deliver assessment methods for the perceived noise environment; to deliver a good practice guide for the end-users; and to show the cost benefit, including the positive effect on urban air quality and CO2 neutrality, of the resulting noise abatement methods.

Validation of radical engine architecture systems (DREAM)

Since the publication of the ACARE goals, the commercial and political pressure to reduce CO2 has increased considerably. DREAM is the response of the aero-engine community to this pressure. The first major DREAM objective is to design, integrate and validate new engine concepts based on open rotor contra-rotating architectures to reduce fuel consumption and CO2 emissions 7Prozent beyond the ACARE 2020 objectives. Open rotors are noisier than equivalent high bypass ratio turbofan engines, therefore it is necessary to provide solutions that will meet noise ICAO certification standards. The second major DREAM objective is a 3dB noise emission reduction per operation point for the engine alone compared to the Year 2000 engine reference. These breakthroughs will be achieved by designing and rig testing: Innovative engine concepts a geared and a direct drive contra-rotating open rotor (unducted propulsion system) Enabling architectures with novel active and passive engine systems to reduce vibrations These technologies will support the development of future open rotor engines but also more traditional ducted turbofan engines. DREAM will also develop specifications for alternative fuels for aero-engines and then characterise, assess and test several potential fuels. This will be followed by a demonstration that the selected fuels can be used in aero-engines. The DREAM technologies will then be integrated and the engine concepts together with alternative fuels usage assessed through an enhanced version of the TERA tool developed in VITAL and NEWAC. DREAM is led by Rolls-Royce and is made of 47 partners from 13 countries, providing the best expertise and capability from the EU aeronautics industry and Russia. DREAM will mature technologies that offer the potential to go beyond the ACARE objectives for SFC, achieving a TRL of 4-5. These technologies are candidates to be brought to a higher TRL level within the scope of the CLEAN SKY JTI. Prime Contractor: Rolls Royce PLC; London; United Kingdom.

Adaptive and smart materials and structures for more efficient vessels (ADAM4EVE)

Materials and structures are called adaptive if they can change certain properties in a predictable manner due to the forces acting on them (passive) or by means of built in actuators (active). Those materials and structures are referred to as smart if they provide best performance when operation circumstances change. The project ADAM4EVE focuses on the development and assessment of applications of such materials and structures in the shipbuilding industry. The types of materials and structures are: - adaptable ship hull structures for optimised hydrodynamic properties depending on varying cruise speed, - adaptive materials for noise and vibration damping of ship engines to avoid induction of vibrations into the ship hull and - adaptive outfitting materials that improve ships' serviceability and safety. Technical developments in the project are structured in three groups: - Materials and structures development: Based on available research results and known applications from other industries, adaptive and smart materials and structures will be adopted and further developed in order to make them applicable in the maritime industry. - Solution development: Driven by different shipyards, several application case studies will be performed, in order to achieve customised solutions for particular vessel types and their individual requirements; classification societies will assure that the solutions comply with existing rules and regulations. - Enabling and assessment of technologies: This group of activities provides support to the other ones on the field of testing, assessment of safety as well as economical and ecological impact, and advice for production, operation and dismantling. Due to the novelty of the solutions to be pursued, further development of the required validation methods and tools is intended, as well as suggestions for standardisation.

Low Emissions Core-Engine Technologies (LEMCOTEC)

The main objective of the LEMCOTEC project will be the improvement of core-engine thermal efficiency by increasing the overall pressure ratio (OPR) to up to 70 leading to a further reduction of CO2. Since NOx increases with OPR, combustion technologies have to be further developed, at the same time, to at least compensate for this effect. The project will attain and exceed the ACARE targets for 2020 and will be going beyond the CO2 reductions to be achieved by on-going FP6 and FP7 programmes including Clean Sky: - CO2: minus 50Prozent per passenger kilometre by 2020, with an engine contribution of 15 to 20Prozent, 2.) NOx: minus - 80Prozent by 2020 and 3.) Reduce other emissions: soot, CO, UHC, SOx, particulates. - The major technical subjects to be addressed by the project are: Innovative compressor for the ultra-high pressure ratio cycle (OPR 70) and associated thermal management technologies, 2.) Combustor-turbine interaction for higher turbine efficiency & ultra-high OPR cycles, 3.) Low NOx combustion systems for ultra-high OPR cycles, 4.) Advanced structures to enable high OPR engines & integration with heat exchangers, 5.) Reduced cooling requirements and stiffer structures for turbo-machinery efficiency, 6.) HP/IP compressor stability control. - The first four subjects will enable the engine industry to extend their design space beyond the overall pressure ratio of 50, which is the practical limit in the latest engines. Rig testing is required to validate the respective designs as well as the simulation tools to be developed. - The last two subjects have already been researched on the last two subjects by NEWAC. The technology developed in NEWAC (mainly component and / or breadboard validation in a laboratory environment) will be driven further in LEMCOTEC for UHPR core engines. These technologies will be validated at a higher readiness level of up to TRL 5 (component and / or breadboard validation in a relevant environment) for ultra-high OPR core-engines.

FP7-TRANSPORT, Transport Innovation Deployment for Europe (TIDE)

The mission of the TIDE project will be to enhance the broad transfer and take-up of 15 innovative urban transport and mobility concepts throughout Europe and to make a visible contribution to establish them as mainstream measures. The TIDE partners will make a range of new and feasible solutions easily accessible to address key challenges of urban transport such as energy efficiency, decarbonisation, demographic change, safety, access for all and new economic and financial conditions. TIDE will focus on 15 innovative concepts in five thematic clusters: financing models and pricing measures (1), non-motorised transport (2), network and traffic management to support traveller information (3), electric vehicles (4) and public transport organisation (5). Sustainable Urban Mobility Plans will be a horizontal topic to integrate the cluster activities. The project will provide a strong approach in methodology, content and outreach. The needs of practitioners in European cities and regions will be a guiding principle. A particular focus will also be on providing guidance for finding cost-efficient solutions (cost-benefit analysis). The project will refine existing and well proven transferability methodologies and integrate them into an easy to apply handbook. Face-to-Face training and exchange events as well as guidelines and e-learning on how to successfully implement innovative solutions will be the key tools to effectively support a wide range of take-up candidates in overcoming real or perceived barriers to implementation. A broad portfolio of dissemination activities will ensure a high visibility of the project. TIDE will actively support 15 committed cities in developing implementation scenarios. They will demonstrate how to successfully prepare implementation of innovative solutions and provide examples to a wider group of cities. An experienced and committed consortium will ensure that the advanced project approach will achieve a well visible impact.

Wireless charging for Electic Vehicles (UNPLUGGED)

UNPLUGGED project aims to investigate how the use of inductive charging of Electric Vehicles (EV) in urban environments improves the convenience and sustainability of car-based mobility. In particular, it will be investigated how smart inductive charging infrastructure can facilitate full EV integration in the urban road systems while improving customer acceptance and perceived practicality. UNPLUGGED will achieve these goals by examining in detail the technical feasibility, practical issues, interoperability, user perception and socio-economic impacts of inductive charging. As one special variant, inductive en-route charging will be investigated thoroughly.

The sustainable freight railway: Designing the freight vehicle track system for higher delivered tonnage with improved availability at reduced cost (SUSTRAIL)

A sustainable and efficient freight transport in Europe plays a vital role in having a successful and competitive economy. Freight transport is expected to grow by some 50 % (in tonne-kilometres) by 2020. However rail has, in many areas, been displaced from a dominant position as road transport services have grown and developed in capability and levels of sophistication that have not been matched by rail service providers. SUSTRAIL aims to contribute to the rail freight system to allow it to regain position and market and the proposed solution is based on a combined improvement in both freight vehicle and track components in a holistic approach aimed at achieving a higher reliability and increased performance of the rail freight system as a whole and profitability for all the stakeholders. The SUSTRAIL integrated approach is based on innovations in rolling stock and freight vehicles (with a targeted increased in speed and axle-load) combined with innovations in the track components (for higher reliability and reduced maintenance), whose benefits to freight and passenger users (since mixed routes are considered) are quantified through the development of an appropriate business case with estimation of cost savings on a life cycle basis. In fact, a holistic approach to vehicle and track sustainability has to be taken, since improvements in track design and materials alone are not enough as demands on the rail system increase. Contributions from the different topic areas (vehicles, track, operations) will be demonstrated on real routes, offering geographic dispersion as well as differences in type, speed, and frequency of traffic. A strong multidisciplinary consortium committed to concrete actions aligned toward a common outcome has been grouped for the achievement of the challenging objectives of the project with a balanced combination of Infrastructure managers, freight operators and Industry, including Large and Small enterprises, with support from Academia.

Arctic Climate Change, Economy and Society (ACCESS)

ACCESS is a European Project supported within the Ocean of Tomorrow call of the European Commission Seventh Framework Programme. Its main objective is to assess climatic change impacts on marine transportation (including tourism), fisheries, marine mammals and the extraction of oil and gas in the Arctic Ocean. ACCESS is also focusing on Arctic governance and strategic policy options. Arctic climate change will have significant impacts on both marine ecosystems and human activities in the Arctic, which in turn will have important socio-economic implications for Europe. ACCESS will evaluate Arctic climate change scenarios and their impact on specific economic sectors and human activities over the next decades. Particular attention will be given to environmental sensitivities and sustainability in the Arctic domain. ACCESS will also engage in close cooperation with indigenous people and other key stakeholders by means of a Stakeholders/End-users Forum and an Advisory Board. HSVA is involved in two out of fife work packages. The one deals with the Study of the opening to marine transportation of the northern passages, north of Europe and Siberia (North-East passage) and through the Canadian Archipelago (North-West passage) as well as the impact of these transportation activities on marine ecosystems and society. The other one deals with how the extraction of offshore oil and gas might be influenced and affected by climatic change, taking into account associated risks.

Green Retrofitting through Improved Propulsion (GRIP)

The aim of the GRIP project is to reduce fuel consumption in shipping by 5% (with individual ships up to 10%) and thus reduce exhaust gas emissions. Its first objective is to give a sound basis for the choice of energy-saving devices (ESD) for ship owners. The second is to give insight into the detailed requirements on the device design by performing an analysis of the interaction between hull and propeller and the structural integrity of the device. For many devices available on the market, it is not clear if and why energy is saved. The choice of an ESD for a ship owner is mainly based on trust. Within GRIP, the most promising ESDs will be studied for several ship types, giving insight into flow changes, relating them to performance improvement and energy savings. Many ships come from Far Eastern yards who keep the hull lines secret. Therefore, a ship owner cannot order an ESD without returning to the original ship yard. Within GRIP, we will develop a digitising technique for determining the hull lines, allowing the ship owner to order the device from, and have it fitted in any European ship yard. The project will deliver an early analysis tool for ship owners to characterise the potential energy savings and associated costs by retrofitting a device on a ship. The second deliverable will be an optimised yard process in combination with digitising of the hull lines. The final deliverable is a detailed design procedure for manufacturers, surveyors and hydrodynamic institutes. The objectives will be validated by designing new ESDs for several ship types. For one of these devices, validation of the energy-saving will be obtained in speed trials. The consortium consists of world-leading hydrodynamic institutes, propeller designers, a European ship operator, a major European yard, a yard association, and a classification society; bringing together a wealth of knowledge on propeller-hull interaction, structural integrity and manufacturing processes.
