Your work will directly impact the efficiency and reliability of our mechanical design processes for future propulsion systems.

Your key responsibilities :

As part of your internship and in direct connection with your academic training, you will contribute to the following missions :

Enhancements to the Elison tool :

• Update documentation and user manuals.

• Integrate new geometries of flanges (including Rotscher cone) and explore coupling with seal components.

• Add composite materials capabilities.

• Update and validate the thermomechanical model embedded in Elison.

• Update the material library.

• Develop a friction coefficient database for screws (with possible integration to a short selection list).

• Improve the user interface and explore adding an automated screenshot/report generation tool.

Development of a sealing sizing tool :

• Participate in creating a calculation tool dedicated to axial and radial sealing design.

Experimental characterization :

• Support torque–tension relationship characterization tests.

Internship Details :

• Duration : minimum 3 months

• Start Date : from January 1st, 2026

• Work Schedule : Full time

• Location : On-site, Le Haillan, 33185, France
