All project partners have been working together for many years on applications for turbomachinery. This shared history provides a common mutual trust and a real motivation to work in a collaborative way through this project. The appendices describing partners are written to put forward their previous works in domains related to the project. It is therefore possible to see the potential and the suitability of each partner for the project. We recall here the activities of each partner on the topics covered in this project and the complementarities and linkages between each of them (through scientific networks, joint projects, research ...).

The structures and systems dynamics team of LTDS has been working for many years on the problems of numerical simulations and experimental tests in structural dynamics. In this context, it conducts researches in nonlinear dynamics applied to rotating structures. The numerous works achieved range from the characterization of bladed disks (updating, identification of mistuning, multistage problems, nonlinear dynamics ...) to rotor dynamics (nonlinear rotordynamics, dynamics of birotor systems, robust nonlinear dynamics...) and to rotor-stator interaction. Its expertise in dynamics of bladed disks and in numerical simulation of nonlinear systems make it an ideally suitable partner for this project.

The LMFA specializes in the characterisation and simulation of the aerodynamic, acoustic and aeroelastic phenomena linked to the turbomachinery, using a combination of numerical simulations and theoretical models. The LMFA expertise in the development of large scale experimental projects (such as the CREATE facilities) is an important element when considering the technical aspects linked to the aeroelastic test rig proposed in this project, where many multi-physics aspects are involved (fluids, acoustics, mechanics).

The LaMCoS team will provide its experience in controlling the frequently nonlinear dynamic behaviour of rotating machines and structures. Its experience in the development of identification techniques, active, passive and hybrid control, as well as related theoretical, numerical and experimental developments, will permit achieving innovative solutions. This dual competence linked to the dynamics of rotating machines and mechatronic systems is one of the strong points of the project.

The MATEIS laboratory will bring its knowledge and its ability in the domain of material realization, which is an essential step in the simulation of dynamic behavior of structural elements in turbomachinery. It will allow to correctly specify the constitutive laws used and the damage modeling due to complex and extreme loadings (forces, temperature). It will innovate by offering choices of new materials in the framework of this project. All test facilities of the laboratory (Geeble, X-tomography, traction under controlled environment), will be an additional advantage and an important contribution to the project.

ENS-Lyon, Laboratoire de physique :
The physics laboratory at ENS-Lyon has both experimental and theoretical skills in a wide field of physics. Its particular expertise in modeling and simulation of turbulence, signal processing and acoustics are perfectly integrated with experimental and numerical issues associated with the project. It will bring a more physical view of problems treated and will help bring out new scientific axis through a fruitful dialogue between theorists and experimenters.

SNECMA is a manufacturer of turbomachines for aeronautics and space applications. With a view to modeling complex physical phenomena that occur in turbomachinery, it has a research department in charge of product design and a team responsible for the development of methods and numerical tools. Themes about the dynamic behavior during the rotor / stator interactions and aeroelastic coupling are major concerns to SNECMA, since turbomachinery performance is closely related to the modeling of these behaviors. Together with its experience in simulation and experimentation around these issues, SNECMA will fully participate in the platform development and its integration into the world of industry and research.

Finally, EDF has a center of excellence in vibration dynamics of rotating machines. As such, the group aims to expand its dual approach to the numerical and experimental analysis of the overall dynamics of shafts in extreme situations. It will bring his vision of issues encounter in the dynamic of energy production systems, and help to develop the platform and its integration into the networks of national and international research. EDF is also planning to transfer its facilities for testing rotating machinery on its future site of research at SACLAY. This transfer will be complementary and in synergy with the experimental facility PHARE.
