One of the most contentious issues facing Formula One this season is the adoption of aesthetically unpleasing nosecones. The sport faced a similar outcry from fans in 2012 when the teams adopted the 'Step Noses'. As always though aesthetics do not bear any significance in the design teams mind when they first approach the design structure for their car. Instead they look at the regulations and choose the most aerodynamically efficient shapes that fit within the regulation boxes set forward for them. 


The Red Bull approach to this freshly presented problem is to use the 'Finger' style approach, this meets with the central tip at 185mm above the reference plane but retains some of the height that would be lost with a full width section. The idea of course is to get as much airflow under the centre section of the floor for onward conditioning and extrapolation of additional downforce. With this in mind the engineers at Red Bull have carefully crafted the front section of the nose in order to meet with regulation, but swiftly narrow thereafter in what Adrian Newey describes as a 'Keel Nose'. At the expansive section of nose tip we also find a carefully crafted slot (circled) which is not only designed to take care of driver cooling, but is also shaped in order to reduce the effects of blockage mitigated by the nose tips overall shape and orientation.

Used by Red Bull in different guises over the last few seasons the team have once again utilised an 'S' Duct in order to realign the airflow under certain flow conditions. In the case of the RB10 an inlet placed under the nose [1] feeds a rearward facing upper outlet [2], in order to smooth the transition of airflow from the nose over the chassis, resisting the airflow’s efforts of detaching due to the noses gradient.

NB. Strangely Red Bull didn't place the FOM camera's on the nosecone during the test in Jerez and so it's likely the team have an aggressive solution for their mounting going forward (similar to Ferrari and Mercedes)

  1. Hi Matt,
    What do you think of Giorgio Piola's theory about S-duct? Here: http://www.formula1.com/news/technical/2014/0/1142.html
    Thanks

    1. It's plausible but without seeing the nosecone off the car we can't prove it one way or another. I stick by the fact the aperture at the front is for driver cooling and the centre inlet under the chassis feeds an S duct / the outlet across the top of the bulkhead. The outer inlets under the bulkhead are undoubtedly aiding the Turning Vanes as Giorgio explains.

    2. Thanks Matt,
      I prefer your explanation better than Piola's

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.
