CEVAA research projects
The CEVAA supports its clients in the context of partnership research projects. We are CIR approved (Research Tax Credit).
To maintain a high level of skills, the CEVAA operates scientific and technological resourcing by deploying its own research programs to develop expertise and innovative methods of NVH characterization.

Other ongoing projects
MIMME : Innovative Methodologies and Experimental Multiphysical Resources for Industrial R&D (Méthodologies Innovantes et Moyens Multiphysiques Expérimentaux pour la R&D industrielle)
Analyses et Surface, CEVAA, GPM, Areelis and 6NAPSE have come together to create MIMME, a relevant testing offer for the aeronautics, automotive, medical, packaging, materials, etc. sectors.
- Develop appropriate methodologies and test benches
- Create a Single Window for the management of an extended validation chain
- Better understand reliability issues through a mixed experimentation/testing approach
MIMME contributes to strengthening the attractiveness of Normandy for the development of an aeronautical center and to provide it with a strong national positioning with differentiating means compared to Paris or Toulouse regions.
The CEVAA is part of the CRIOS project, which aims to develop a miniature cooling solution for electronic components in harsh environments. Led by the Norman SME AREELIS Technologies, this project labeled NAE and supported by the Thales group, is co-financed by the Normandy Region and the Operational Program FEDER Normandy, and brings together 5 other Norman partners: GPM (University of Rouen) and LOFIMS (INSA Rouen), CEVAA, ANALYSES & SURFACE and the SME PROJACTION.
The objective of the CRIOS project is to carry out a proof of concept of the integration of existing Phase Change Materials (PCM) in an electronic system/component to optimize its thermal behavior during high transient power demands.
To achieve this goal, the CRIOS project plans to approach the development of this concept from two aspects:
- Experimental modeling, which will make it possible to demonstrate the integration of a phase change material on an electronic system/component and the characterization of this experimental model on a test bench in laboratory conditions. The thermal behavior of the experimental model will be evaluated on a mission profile and a system provided by THALES OPTRONIQUE. This model will be preceded by the design of test specimens to verify the “insulation” approach on the one hand and the “dissipation” on the other hand, the idea being to imagine, for the future and following the CRIOS project , the development of a thermal switch.
- These experiments will be preceded by numerical modeling, which will make it possible to apply all the theoretical laws to the two test specimens and to the experimental model and to establish the concept’s efficiency thresholds and their evolution over time.
This project aims to reach a TRL 4 technological maturity.
This project culminated in late 2018 with a promising solution for the industry.
This project was supported by the Normandy Region and the Operational Program FEDER Normandy. Normandy Region et le the Operational Program FEDER Normandy.
R&D / R&T projects examples
