Mécanics.
As experts in mechanical engineering, we cover acoustics, calculations, numerical simulation, and mechanical design.
Our expertise
Our expertise also includes vibration analysis and related testing (organization, test monitoring, etc.), enabling us to provide comprehensive, customized technical solutions tailored to your needs.
Acoustics.
- Acoustic impact studies: on-site measurements, numerical simulations, diagnostics, advice, and support.
- Internal acoustic and vibro-acoustic comfort for all types of vehicles (measurements, numerical simulations, acoustic treatment solutions).
- Aeroacoustic numerical simulations (acoustic signature of an aircraft, turbomachinery, landing gears, CFD/CAA coupling).
- Acoustic signal processing.
- Development of acoustic and thermoacoustic measurement benches.
Structural analysis and mechanical design.
- Numerical modeling: CAD, drafting, model simplification, defining contacts, boundary conditions, and loads, Finite Element discretization.
- Structural analysis: static, dynamic, vibrational, nonlinear, thermal.
- Design and manufacturing of operational prototypes.
- Preparation of technical drawings and calculation reports.
- Test-to-simulation correlation and model adjustment.
Vibration studies.
- Linear or nonlinear calculations based on transient or steady-state excitation (shock, seismic, harmonic, random).
- Vibration fatigue calculations and lifetime estimations.
- Experimental modal analysis (instrumentation and analysis).
- Material and fluid characterization using vibratory methods.
- Development of vibration damping systems (specifications, numerical simulations, custom test bench development, and validation tests).
- Validation, robustness, and fatigue vibration tests.
- Multi-axis vibration testing on 6-axes hydraulic shaker (Equipex PHARE-3).
Fluid mechanics.
- Aerodynamic studies of internal and external flows on vehicles and propulsion systems.
- Numerical simulations in aeroelasticity (fluid-structure coupling).
- Analysis of interactions between fluid mechanics and heat transfer by conduction, convection, and radiation.

Client. AVNIR Engineering – 2025
After working there for over 5 years, I can say that AVNIR offers its employees the opportunity to work on high value-added projects and to quickly develop strong technical skills. The management team is always supportive and attentive to its employees. The great team spirit is fostered through regular after-work events and unforgettable seminars.
Mathieu F. AVNIR Engineering engineer- 2025
I worked at AVNIR Engineering for almost 2 years as a consulting engineer. I want to thank the management team for giving me the opportunity to return to a rich professional activity after my maternity leave and time with my family.
Thank you for your warm welcome, your attentiveness, your kindness, and the calm at-mosphere you know how to create. Thank you for your professionalism accompanied by smiles, good humor, and the close relationship you maintain with your employees.
FD. AVNIR Engineeering engineer – 2024
AVNIR’s dynamic, responsive team is always ready to listen. The many initiatives aimed at improving workplace well-being, and the (very) positive atmosphere experienced during company seminars, are proof of this. I will keep excellent memories of my time at AVNIR Engineering.
Guilhem M. AVNIR Engineering engineer – 2024
A human-scale service company with a management team that is always very available and attentive to our requests.
Regular visits from management to the client’s site to ensure everything is going well.
Excellent integration with quality seminars and after-work events.
The mission is chosen before hiring, so there are no surprises.
Moreover, the company is not obstructive when opportunities arise with the client.
A very good first experience in the professional world!
Florian M. AVNIR Engineering engineer – 2024
My position as a Design and Calculation Engineer with AVNIR ENGINEERING marked my first step into the professional world after completing my studies, and it was a very positive experience. I gained exposure to major French industrial companies and learned a lot. I was always well-supported by AVNIR’s management for any problems or questions, and the atmosphere of exchanges between the team members helped me feel at ease during the early years of my engineering career.
