Aerodyne

Hello.

I am Matthieu BARREAU, 35, Paris, France.
I am a professor of design / engineering / fluides mechanics/ Thermodynamics etc ... at the IUT de Cachan and fanatic of power optimization.

I have also always been interested in design, I would say philosophically! For me, the art of design: adapting means to ends, it is a form of politeness. How to make a minimum cost.
Curious and eager to learn more about the subject, I quickly participated in the association INTER-ACTION I am an active member and webmaster(association of creative rescue of aérotechnic knowledge )
http:// inter.action.free.fr
In this web site I have write pages about aerodynamic refinement of cars :
Inter Action

Passionate about aviation (flight + glider pilot), but also mechanical design, I eventually want to design and build my own airplane. That's what I do at the IUT with my students: Design of an ultralight bi place, 200 kg payload, 60 hp, 200 km / h cruise 220 km / h max.
It is a lengthy task and each year my students work on part of the aircraft.


I also work on velomobiles and fuel efficient vehicules.
I have wrote a paper on this (sorry in french)
http://inter.action.free.fr/publications/auto-eco.pdf

The blog attached to the association for having an overview of what I do with my students:
AERODYNE



Many thanks for all your experimentations.

Best regards.
Matthieu

Welcome to the site. It sounds like you'll fit in great here. What car do you drive and what kind of mileage do you get with it?

Matthieu - toujours heureux d'avoir un autre expert a bord.

Did you know that someone here already posted a link to your pdf (RÉFLEXIONS SUR L’ÉNERGÉTIQUE DES VÉHICULES ROUTIERS)?

I've seen it before. Possibly Tasdrouille or Groar linked to it ... Oui, je l'ai trouve - c'etait groar: http://ecomodder.com/forum/showthrea...33-a-5122.html

Beinvenue a EcoModder!

PS - I hope you don't laugh too much at some of the aerodynamic "discussions" and misunderstandings you will surely see here!

Darin, ton francais s'en vient pas mal du tout. Denis linked to the paper first, but I was quick to add it to the white papers sticky when I saw how good it was.

Bienvenue Matthieu!

Ca fait toujours plaisir d'avoir un cousin francais a bord!

I am looking forward to seeing your contribution to the community in our threads. It is always great to have experts join our discussions and set the record straight when we get things wrong.

BTW: How did you find the site?

This page of Matthieu's is good: Inter Action - lots of great aero pics.

I see images there from two other EcoModder members.

Yeah, that's one of Phil's images (I think he made it - talked about it here): http://ecomodder.com/forum/showthrea...html#post70206

The other image is the tuft tested rear of the blue Honda Civic. That's Cd's car, if I'm not mistaken.

Et... faut que je dis que c'est pas difficile de "parler" en francais avec l'assistance de Google Translate
