Project overview

The purpose of FACTOR is to make a new breakthrough in the core engine design by taking into account not only an isolated module but a complete system composed by the combustor and the turbine. The link between the combustor and the turbine in an engine is very tight and all engine manufacturers are putting a strong effort to master this interface: extremely hot gases, variable boundary layers, turbulence effects and inherent unsteadiness are some of the phenomena making this region of the engine a difficult interface. This interface still requires strong improvements as gas turbine designers are lacking the experimental data needed to optimize its design.

The FACTOR project will exploit the results achieved by and the guidelines derived from all previous projects and will create new links between European combustor technology and turbo-machinery experts leading to a new breakthrough in the field through:
  • The development at European level of an innovative experimental test infrastructure coupling a combustor simulator with a HP turbine for aerodynamic and aero-thermal measurements. The FACTOR test infrastructure will be used to collect the experimental data needed to study and understand the secondary flow transport and mixing through the HP turbine and to analyze the thermal stresses in the heat transfer analysis.
  • The integration of these experimental data into thermo-mechanical design techniques and simulation software used to optimize new HP turbine components.

Based on the engine development cycles, all the partners will be involved in the whole design process, including the modules design and manufacturing.
The technical Work Breakdown Structure is split as follows:
  • WP1 - Component design and manufacturing
Study and design separate combustor and turbine concepts that will be integrated together to ensure mechanical, thermal and aerodynamic performances match specifications.
  • WP2 - Instrumentation design & manufacturing and rig adaptation
Upgrade the new turbine test rig hosted by DLR to ensure that the combustor / turbine module and the necessary equipments and services (fluid piping, instrumentation accesses, etc.) are achieved.
  • WP3 - Integration
Perform the components integration activities within the whole test rig.
  • WP4 - Measurement campaign
Perform aerodynamic and aero thermal measurements to build-in the most all comprehensive data base.
  • WP5 - Lean burn influences on low turning strut heat transfer
Carry-out the aerodynamic and heat transfer measurements on the Oxford Turbine Research Facility
  • WP6 - Synthesis of experiments and computations
Lead the pre-test and post-test CFD activities. Ensure appropriate interaction between the partners involved in the experimental and numerical activities. Establish data transfer formats between the partners. Analyze the generated CFD data and write guidelines on modeling combustor-turbine interaction.

In addition, a dissemination and exploitation work package, WP7 "Dissemination and Exploitation", will focus on the integration of requirements of the SAGE (i.e. engine) ITD platform of CLEAN SKY and support the corresponding transfer of results. This work package will also rely on interactions with ERCOFTAC (European organization for Flow, Turbulence and Combustion) and its Qnet-CFD.
Finally, a management work package, the work package WP8 "Management", will take care of the proper organization and management of the project.
