Structures - Sizing

Objectives
The aim of this teaching unit is to acquire the concepts and methods essential to the dimensioning of aeronautical structures.
Skills acquired

Be able to formulate a problem with its boundary conditions, approach it in a simple way, solve it and conduct a critical analysis of the result
Validate a model by comparing its predictions with experimental results and appreciate the limits of validity of a model
Use CAD tools (Computer Aided Design) integrating trade expertise
Be able to dimension a metal or composite structure in statics.
Identify the main families of materials and their properties.
Choose a material for a mechanical part, taking into account its functionality and physical, technical and economic constraints.
Interpret experimental data to envisage their modeling.

Competencies acquired level supervised mastery

Design and dimension mechanical systems
Communicate and work as part of a team Manage and lead a work unit or project group


Competencies being acquired

Mobilize a broad field of fundamental and technical sciences related to aeronautical and space mechanical systems, and have the analytical and synthesis skills associated with them
Choose and implement analysis and characterization methods relevant to mechanical systems
Design, dimension, implement and test a metallic or composite repair/modification
Have a global systems approach to mechanical systems Reason in a context of international regulatory constraints
Integrate into a professional environment in France or abroad Communicate orally and in writing in English

Evaluate one's own skills and manage one's career path
