Red Bull having been the pack leader for the past few years had a surprisingly poor start to the 2012 campaign. I have alluded to the problems they were encountering in my previous articles but for Bahrain the team have opted to swallow their pride and adopt a package more akin to that on the McLaren and Sauber.

Their new package encourages the downwash effect from the top of the sidepod to stay attached with the exhaust helping to flow the air downward (Coanda Effect) whilst also keeping the flow from around the side of the sidepod attached for longer. Previously their airflow convergence was hampered by the use of a Tunnel feeding the sideways flow inbound through the false floor. (Picture below). Further to this Red Bull have added the same cooling / vortex generators on the top edge of the sidedpod that are found on the MP4-27. Along with reshaping the engine cover to push the airflow into the path of the downwash and sidepod flow generated by the use of the Coanda Effect.   All of this leads to more airflow over the rear floor which in turn generates more rear downforce.

Lastly here is a very basic picture of how the flow is is being directed around and over the sidepods (Yellow Markings), the circled area is the cooling slots that have been added and will also slow down the flow at the top end of the sidepod leading to the engine cover promoting better flow into the downwash area.

  1. This blog site is pretty good! How was it made . I view something genuinely interesting about your site so I saved to my bookmarks . You can visit my site.


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.

I'm still doing the technical image gallery for each GP with the continued support of friend of the site Sutton Images. However, as always my time is limited and so this might not be updated as quickly as it once was, so keep checking back.

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.
