  1. Why is the model scale in the wind tunnel 60%? How do F1 regulations limit aero testing? Enjoy the final video of our Wind Tunnel Explained series!

    So… We're at the end of our 8-part series… Which one of the 8 parts did you like most or find most interesting? We hope you learned a bit (or two) about the incredible efforts behind running a Formula One team watching these videos!

  2. Can you do a series on CFD? How it has evolved? Where is it going? Do you start with CFD and validate in the wind tunnel?

  3. Loved the feature! Gained some really cool insights! Thumbs up for that!

    Would be cool if you can do something about CFD or quality control in the future.

  4. Thank you very much Mr. Willem. I like your way in simplifying the most complicated things, I am so proud that I met you at Silverstone, hope to meet again next year.

  5. Great, great, great series. Thank you very much. A am an engineering student and I have enjoyed the videos very much. Very good ending as well, explaining the significance of the scaling factors, great insights.

  6. I'd love a short snippet of Williem saying "Other people might be watching" to insert into random videos from time to time.  Comedic gold!

  7. as you said FIA has made some restrictions on testing hours.
    how do they ensure that team abide by rules of no. of hours of testing,
    is there a FIA representative always present in a team's factory??

  8. can you show me/us a picture of chassis, any year would do, I would just like to know what it look like
    Thank you for nice series

  10. Can you PLEASE have Willem Toet  explain how high noses increase downforce and how diffusers work ?  Do they they "curve" or "expand" airflow ?  I have heard F1 diffusers are not strictly diffusers like in a duct.  How can the strakes be set up for a peaky diffuser or one with more benign downforce (soft instead of hard abrupt stall) ?

  11. Why is the base pressure of the car "fixed" with respect to the diffuser ?  Is the diffuser a "diffuser" like in a duct ?  I have read the diffuser used in motorsport is a diffuser geometrically, but not in function ?  It was suggested in an issue of Bernoulli magazine that diffuser simply "curves" airflow ?  But I fail to see how the airflow is not expanding as in a duct ?  Clearly the whole this is not sealed as in a duct but the diffuser does "expand" and "curve" the airflow to a FIXED BASE pressure ?  Why is it fixed with respect to the underbody ?  How can you make peaky or less peaky diffuser in general ?  How does high nose increase rear downforce potential ?   I love these unique videos !!!!  Technology is incredible !!!

  12. For the "Translation of Forces based on speed" Diagram at 6:03, shouldn't the faster wind speeds be attributed to the 60% scale model in order to keep the Reynolds numbers of the cars equal, and the tests dynamically similar?

  13. Hello, all right?
    Initially, I want to thank you, for this series of video helped me understand much more this science is the development of a formula 1 in wind tunnel. Also thank SAUBER that through actions such as these, "opens the doors of his factory" to us (F1 fans and logically, SAUBER fans). I leave with suggestion to hold a series about grip. Thank you!

  14. you didnt know that I was watching and now you ruined your next season, we heard everything we needed! 😀

    still listening so keep making those videos 😛

  15. How much Sauber targets next season (2015) to make improvements? the work you do in wind tunnel hopefully helps to improve the car. even i'm fan of rival team, i got respect to each team and specially ones that have been around long time (like Sauber has been)

  16. You said there were hundreds of pressure sensors? Where are they? If they're on top of the skin of the car, they'd throw off the car's aerodynamics, if they're under the skin, wouldn't you change the aerodynamics when you removed them? Does that make sense?
