In a outwardly minor alteration in Singapore, McLaren have adjusted the ladder winglets that sit astride the rear crash structure (above).  Responsible for upwashing the airflow in the region and creating a centralized connection between the diffuser, exhaust, main Y100 winglet (Monkey Seat) and rear wing any changes clearly has impact on several flow structures.  We must therefore bear in mind that the team return to the use of both wishbone wings for Singapore, having just used the lower ones at the last few races; whilst they changed the central portion of the diffuser in Spa.
As we can see from their previous Y100 ladder winglet (above) the upper section is designed very differently, not only do we now find an extra section at it's base with which to release airflow, we also see the zircotec painted (silver tips) have been removed.  This will clearly have an impact on the trajectory of the exhaust plume, with it most likely having a more spanwise effect on the upper wing surfaces.

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 Motorsport.com 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.
