Pyrotechnics & Propulsion Advanced Master - Detailed program

The course covers 2 semesters:

  • 1 semester of applied training (starting on September) and
  • 1 semester devoted to a final thesis in an industrial or academic environment in France or abroad, with a thesis to be defended in September.

All courses are given at ENSTA Bretagne either by research faculty members or by engineers who are specialists in their field of industry :SNPE, SNECMA, CEA, EADS, CNES, DGA, MBDA...

CU 5.4 Elective project

Studies led in the pyrotechnics industry can require delicate handling due to their multidisciplinary aspect. The main objective of this project is thus to enable a student to fully appreciate the inherent difficulties in this field. It enables:

  • the application, through case studies and practical work, of the concepts introduced during theory classes (shock waves, detonation, combustion, energetic materials),
  • the application of project management and result communication tools,
  • the experience of team work.

Subjects:

The subjects are proposed by companies in the field of pyrotechnics and correspond to concrete case studies and the real concerns of these companies. They are treated in a group. A supervisor from the world of industry is automatically assigned to each subject. He is not only the students’ spokesperson, but also their mentor and client.

Examples of subjects: Dimensioning a 15t Rocket Motor (SPS), Modeling a Pyrotechnic Expandable Tube (Dassault Aviation), Study of the Plasticization of a Projectile (CNES), Analysis of Debris Impact on a Space Structure (LCD) etc
