Aerodynamics - 2021

Sub- and transonic aerodynamics


This course aims to introduce digital and experimental tools for subsonic and transonic flow studies.

The main aerodynamic characteristics will be covered for certain types of aircraft with a look at their specific issues and the current research routes.


The course lasts 5 days (30 hours) and includes:

  • 14 lectures
  • 1 visit to the Chalais-Meudon wind tunnel at ONERA


Theoretical developments are limited to a minimum; however, a significant part focuses on the applications and provides participants with an overview of the performance and aerodynamic problems of the main types of aircraft.


Course level: Advanced

This course is intended for engineers and senior technicians with basic knowledge of fluid mechanics or aerodynamics wishing to update or supplement their knowledge of sub- and transonic aerodynamics.

Prior completion of course FMA 006 "Introduction to aerodynamics" or equivalent knowledge is recommended.



Director of the Department of Aerodynamics, Aeroelasticity, Acoustics at ONERA
