Das Projekt "Main Annulus Gas Path Interactions (MAGPI)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Rolls-Royce Deutschland Ltd & Co KG.In a modern aero engine, up to 20Prozent of the main annulus flow is bled off to perform cooling and sealing functions. The vicinity of these bleed ports and flow sinks is characterised by complex unsteady swirling flows, which are not fully understood. Even the most up-to-date numerical tools have difficulties predicting the behaviour of the secondary flow system when interacting with the main annulus. The project addresses interactions between main gas path and secondary flow systems in commercial gas turbines in response to Research Activity AERO-2005-1.3.1.2a Concepts and technologies for improving engine thermal efficiency and reducing secondary air losses. Experiments are planned on turbine disc rim and compressor manifold cavity heat transfer, hot gas ingestion, and spoiling effects of cooling air flow and their impact on turbine and compressor performance, as well as a reduction of secondary air losses. The experimental data will be used for better understanding of the complex flow phenomena and improvements of platform and cavity design. Furthermore, the industrial partners will validate their design tools with these test data and improve their prediction capability of secondary flow systems when interacting with the main gas path. The expected results are a reduction of cooling and sealing airflow rates, improvements of the turbine and compressor efficiency and increase of the safety margin of the engine components by better cooling. Expected technical results are: - Knowledge of the interaction phenomena and its effect on cavity heat transfer, spoiling and performance, - Experimental results for validation of improved numerical tools for secondary flow systems, - Optimised design methods and CFD best practice guidelines. The targeted outcome will contribute to the ACARE goal of reduced CO2 emissions via reduced fuel burn of 2Prozent to improve the environment and strengthening the competitiveness of European gas turbine manufacturers.
Das Projekt "New Aero Engine Core Concepts (NEWAC)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Rolls-Royce Deutschland Ltd & Co KG.NEWAC will provide a step change for low emission engines by introducing new innovative core configurations to strongly reduce CO2 and NOx emissions. This breakthrough will be achieved by developing and validating new core configurations using heat management (intercooler, cooling air cooler, recuperator), improved combustion, active systems and improved core components. NEWAC will design and manufacture these innovative components and perform model, rig and core tests to validate the critical technologies. The NEWAC core configurations include an Inter-cooled Recuperative Aero engine (IRA) operating at low overall pressure ratio (OPR), an inter-cooled core configuration operating at high OPR, an active core and a flow controlled core operating at medium OPR. NEWAC will complement past and existing EC projects in the field, e.g. EEFAE in FP5 and VITAL in FP6. The main result will be fully validated new technologies enabling a 6Prozent reduction in CO2 emissions and a further 16Prozent reduction in NOx relative to ICAO-LTO cycle. Most importantly, the project will address the challenges involved in delivering these benefits simultaneously. NEWAC will deliver together with EEFAE (-11Prozent CO2, -60Prozent NOx), national programs and expected results of VITAL, the overall CO2 reduction of 20Prozent and the NOx reduction close to 80Prozent at a technology readiness level of 5, contributing to the attainment of the ACARE targets. NEWAC will achieve this technology breakthrough by integrating 41 actors from the European leading engine manufacturers, the engine-industry supply chain, key European research institutes and SMEs with specific expertise. The advance and benefits that NEWAC will bring to Europe in terms of more efficient and environmental-friendly air transport will be disseminated widely to all stakeholders. Furthermore a training programme will ensure the transfer of expertise and knowledge to the wider research community and especially to the new member states of the EU.

Das Projekt "Predictive methods for combined cycle fatigue in Gas Turbine Blades (PREMECCY)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Rolls-Royce Deutschland Ltd & Co KG.The modern gas turbine is a complex machine, the design and development of which takes many months and costs Millions. The European gas turbine manufacturing industry is under pressure to minimise the resources required to bring a new design to market, due to global competitive pressure and increasing customer expectations. Accurate design and prediction tools are keys to success in this process. The PREMECCY project identifies the field of rotor blade Combined Cycle Fatigue (CCF) as an area where there are shortcomings in the existing industry standard design and prediction tools and thus where significant benefits can be achieved. Rotor blade CCF accounts for up to 40Prozent of the total number of issues that arise during an engine development programme and a similar proportion of in-service problems. These issues cost the industry Millions in both maintenance and redesign costs. The primary objective of the PREMECCY project is to develop new and improved CCF prediction methods for use in the design process. These will halve the number of development and in-service CCF problems thereby reducing the time and cost required to develop a new engine and reducing the operating costs once in service. They will also enable the design of lighter, more efficient blades, reducing engine sfc. In order to develop the new prediction methods the project will first generate high quality material test data. Advanced specimens and testing mechanically, geometrically and environmentally representative of operating conditions will be used to verify the enhanced methodology. All industrial partners are in a position to exploit the resulting methodologies within their existing design processes. The 15 strong consortium includes 9 major European gas turbine manufacturers, 1 specialist SME and 5 world-class research facilities. The complimentary expertise and experience of the consortium represents an optimised resource with which to achieve the project's challenging objectives.

Das Projekt "Prevention, information and early warning pre-operational services to support the management of risks (PREVIEW)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: INFOTERRA France SAS.PREVIEW proposes to develop, at the European scale, new or enhanced information services for risk the management in support of Civil Protection Units and local or regional authorities, making the best use of the most advanced research and technology outcomes in Earth Observation. Services will be validated under pre-operational conditions. The risks may result from the direct impact of atmospheric events, from their hydrological consequences or from geophysical events and in some cases be worsened or directly caused by industrial activities. The challenging issue is to enhance risk mitigation through better prevention, better anticipation and more accurate assessment at various time and spatial scales of situations at risk, improved timely dissemination of meaningful and adapted early warning information, fitted to the societal needs and to the operations of rescue forces. This has to be done in a joint effort of all actors and citizens to develop risk awareness and culture. The main axe of development through PREVIEW is: Improvement of the services contents: quality and harmonisation of the information services supporting the decision making at the operational level, improving information collection, aggregation and intelligence methodologies, developing synergies, cooperative work and inter-operability capacities among operators for a widespread application of the best solutions at national, regional, and European scale.
