I'm Matthew Somerfield, a freelance journalist focused on the technical elements of Formula One. It has been a pleasure to provide content via this site for the last 5 years, which has led me to several paid freelancing jobs along the way. I'm currently plying my trade with and working alongside the legend that is Giorgio Piola.

This has seen the content here diminish as a result and I'd like that to change. In order to accomplish this I need your financial support, as I need to break free of the shackles of doing this part time. If you like the content I've been producing and want more of it I'd ask that if you can spare some change each month it'd go a long way towards transforming this site into the technical behemoth I know it can be.

As such I've set up a 'tip jar' over on Patreon and will continue to set goals and rewards based on our success -

Mercedes made a small alteration to their front wing in Japan which should provide some additional balance for the driver.  The change was made aware to me by Allen Lopez via Twitter with tubercles added to the trailing edge of the one but last flap.  If you're unfamiliar with the term, tubercles were used by McLaren from Germany last year and applied to both the mainplane and top flap of their rear wing:

The application of these by Mercedes on the front wing will be similar to those applied by McLaren, with the 'teeth' helping to overcome a steeper angle of attack.  The pointed trailing edge means that the airflow leaves it at differing intervals, creating a small vortex as the airflow intertwines.  In the following image I've illustrated how this would occur, but please bear in mind this is not accurate more a means to explain the process.

Ordinarily steeper angles of attack mean that supplying airflow to the trailing egde of the flap becomes critical, if the flow seperates early it can destroy the entire wings efficiency, reducing performance at the transition point for medium speed corners.  These small vortices created by the tubercles are used in order to delay seperation, widening the flaps operating window.
