All the aero engine manufacturers of Europe, three research institutes and five universities have joined their expertise and resources in the project AIDA to reach beyond the current state-of-the-art in aero engine intermediate duct design. The AIDA project will strengthen the competitiveness of the European aero engine manufacturers and improve the environment, which are two objectives of the priority 4 "Aeronautics and Space" of the 6th framework programme, through the achievement of the technical objectives given below:-Improved understanding of the flow physics in aggressive intermediate ducts-System integration - Knowledge of how aggressive ducts interact with neighbouring components -New advanced vane-duct integration concepts for optimised engine layouts-Development and tests of very aggressive intermediate ducts-Establishment of validated analysis methods and "CFD Best Practice Guidelines" for duct flows-Tests and modelling of novel passive separation control devices for super-aggressive ducts-Development of new numerical optimisation techniques for intermediate ducts-Establishment of design rules and a validation database for aggressive intermediate ducts.
The short-term to long-term exploitation of these technical achievements will benefit to the European aeronautics and the environment through the use of a new generation of engines, which will lead to:
-2% reduction in fuel burn through 1-2% reduction in engine weight & length and 0.5% and 1.5 % increase in compressor and turbine efficiency, respectively
-New low engine noise levels through the use of ultra-high-by-pass-ratio jet engine configurations-2.5 % better operating margin for long.
-Haul aircraft through reduced fuel burn together with 5% and 70% reduction of aero engine development costs and time-to-market, respectively. The project hinges upon six technical work packages with clearly defined milestones and deliverables and one management work package.
