As I've already blogged about this weekend Ferrari have made changes to their rear wing assembly, whilst the other post focused on the new endplates this one will look at the changes made to the wing profiles.

The changes made to the endplates allow the team to run with a much more aggressive AoA (Angle of Attack) thus generating more peak downforce.  Of course the problem with more downforce is that invariably you'll also generate more drag, meaning the team have made a design change to the rear wings upper flap. 
Usually the teams philosophy is to utilise two V grooves in the flaps upper surface (above), these reduce the surface area available, bleeding off some of the drag induced at higher speed.
However their presence in Yaw doesn't represent the same problem, as the grooves are designed to act in a way that maximises downforce before reducing drag.

The new top flap (above) has been designed with just a singular, much larger, centralised V groove, much like most of their rivals use.  The idea being that the singular V groove, although larger, allows for much more control in how the wing reacts to changes in attitude.  Furthermore as teams look to use the exhaust plume, that now lies on the cars centreline to assist in downforce generation and drag reduction, moving the V groove to the centreline enables more control.


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.
