ModAw - Innovative design methodology for next generation aircraft engines
Overview
Background & policy context:
The aviation industry undergoes an enormous growth and development process, demanding more energy efficient, less polluting, quieter and cheaper aircraft. At the same time, aircraft manufacturers and airlines are faced with the global problems of decreasing fossil resources and climate change. To master these problems, the aviation industry has to develop new technologies.
Objectives:
The ModeAw project has the objective of improving existing design tools. The whole design process is optimised for quality and reliability. Design cycles should be accelerated and the scope of the processes extended. This can be seen as a first step to developing new engines with higher efficiency and fewer emissions.
The main objective of the ModeAw project is broken down into five sub-goals, which correspond to the five project work packages:
- Develop new methods for a more precise forecasting of the temperatures on turbine blades.
- Improvements in calculation methods for turbine flow.
- Develop a new method to calculate the surge limit.
- Optimize the oil supply, achieving 50% less power dissipation at the bearings.
- Improve the methods for lifetime calculation of mono- and polycrystalline materials
Methodology:
The project was divided into five work packages, each one based on different disciplines in research and development.
- WP1: Efficient cooling systems
- WP2: adaptive CFD for turbine flow
- WP3: interdisciplinary assessment of operability
- WP4: optimized oil supply for high performance bearings
- WP5: improved calculation of lifetime for materials
