Who are we ?

CNES is a key player in France’s international influence. Since Ariane’s first launch 40 years ago, when Mascot landed on the asteroid Ryugu, CNES has imagined, designed and developed innovative space solutions while contributing to the sovereign missions of the State, in particular for Defense and scientific progress.

Adventure location:

Within the launcher department, CNES offers you a professional opportunity in the field of aerospace engineering specializing in the dimensioning of composite structures for launchers.

The launcher management contributes to the operation of Ariane 5, Vega and Soyouz launchers, participates in the development of Ariane 6 (in collaboration with ESA) as well as Vega-C and invents the launchers of the future through Callisto, Thémis and Ariane Next.

As part of these missions, the team dedicated to “Structures, Thermal & Materials” aspects the team develops the structural elements of European launchers and more specifically:

  • arrange the stages of the launchers and design their structural elements such as tanks, skirts, upper part elements;
  • select materials and processes;
  • optimize and size the structures

Why start this new adventure with CNES?

Composite materials have been present for several years on launchers, in particular on its upper part (adapters, cap) and on inter-stage skirts, but the race for performance leads to wanting to use these materials more widely with a multiplication of the number of applications (cryogenic tank, solid propulsion capacity taking into account the reuse of launchers).

For this, the methods of design and dimensioning of composite structures must evolve to respond to these new needs with relevance. This is the reason why CNES is working on the development of these new design methods to integrate within its own software platform to meet the needs of pre-projects, new developments, but also to support the operation of launchers. current.

In this context, our future apprentice will be involved in the development of these new methods which will allow to take into account new architectures, but also more complex phenomena specific to composite materials.

Ready for takeoff?

In order to be in line with the progression of the student within the framework of his training, and taking into account the increase in skill which will be acquired as and when, an activity program with increasing complexity is planned on the 3 years of work-study training.

The professional path will be divided into 3 coherent phases of the 3 years of learning (possibility of adapting the phases to a 2-year course):

  • Phase 1: acquire the “classic” methods and tools for application on the dimensioning of an existing structure.
  • Phase 2: evolve towards more complex methods which integrate the optimization aspect to allow the dimensioning of structures with less conventional architecture. The improvement of these methods will be done through recipes on pre-project applications.
  • Phase 3: develop new sizing methods for modeling damage (delamination, etc.) in composite structures and thus, implement them within a tool to apply them to a specific case.

Profile of candidate sought:

And if it were you? 

CNES is looking for his/her future apprentice in the 1st year of engineering school or equivalent BAC + 3 university to follow a specialized training in structural mechanics.

You have a taste for composite materials, modeling (analytical and finite elements) and programming.

You are autonomous, motivated and ready to take initiatives. Teamwork is one of the essential components of this position. You also have a pronounced taste for technological and spatial innovation.

CONTRACT: Work-study contract (professional, apprenticeship)
DURATION: 24 to 36 months
WORKING TIME: Full time
EXPERIENCE: Less than 2 years
EDUCATION: Bac, bac professionnel
