A brief overview of 'Coanda' style exhausts:


  1. A nice explanation. Gary Anderson - the best bit of the BBC F1 website and TV coverage, also explained this, but the article appears to have been taken off the website as a "search" only brings up a mention in one of Benson's otherwise weak reports. There is a good Wikipedia page which also introduces the person after whom the effect was named. Keep up the good work!

    1. Hi Ted

      Thanks for the feedback, I did have a little bit in there about Henri Coanda but decided to edit it out as it wasn't 100% relative.

  2. Good explanation as said before, just have a couple of questions:
    1) Could you change the actual end of the exhaust pipe instead of a full circle exit cyclinder shape ?
    2) Also could you not enclose the Downwash area/Tube that feeds the airflow from the exhaust or at least make it more narrower ? (I know you mentioned +10 +30)

    Keep up the good work


  3. Thank you for the video explanation, @Anonymous 16th Feb, you can change the tube that you find faulty instead of the whole exhaust cycle. The advantage however of changing the whole cycle is that you get parts that fit into each other without any chances of faults. See exhaust parts at

Whilst I'm trying to keep atop of the blog you may have noticed of late that there is less content appearing. For those of you that haven't realised, most of my work has now been moved over to where I'm working with Giorgio Piola.

As some of you may have found out already I'm also working with the Missed Apex crew on their podcast from time-to-time, either doing race reviews or dedicated 'Tech Time' shows.

I've embedded the latest version of the podcast below and will update this a frequently as I appear. However, please head over to Itunes if you want it to appear in your player when episodes are available. The show is great to work on and has a great lineup of 'regulars' but has also enticed some bigger names recently too, with Will Buxton and Bradley Philpot on shows during the summer break.
