The first few minutes show the viewer some of the details that goes into making a Red Bull Racing car (see my article here on some of this: http://somersf1.blogspot.co.uk/2012/12/red-bull-racing-historic-technical.html)
Front Wing: As usual on F1 launch cars thiese don't change drastically from their 2012 challengers but it's an area where i'm sure Red Bull will have invested time due to the increased load testing introduced throughout 2012. Some minor alterations to the design of the top flap with the upper inner portion of the flap looking like it protrudes vertically and is has a more bulbous top edge. I suspect we will see a new design during testing.
In terms of the nose the frontal section of the nose carries the hammerhead appearance it's predecessor did at the end of 2012 courtesy of the FOM camera mounting positions. The Nose tip itself once again droops down from the pylons forward in stark contrast to their rivals who seem intent on clearing as much space under the nose as possible.
Retained from the Singapore onward spec under the nose is the curved underbelly which goes some way to manipulating the airflow heading toward the keel and then onward to the Sidepods. Newey and the team not one to shy away from thinking of aero over aesthetics have kept a step nose on the RB9. Instead of the abrupt shelf like step with cooling slot on the RB8, the RB9 utilises the vanity panel to extend the step transforming it into a slope much like how Lotus have done with the E20/1.
As we can see from the 2 pictures the nosecone region tapers in toward the bulkhead allowing the step to also taper outwards. From the lower nose picture we can see how this sculptured piece of bodywork allows the air to migrate from the nose over the control arms.
The Front Wing pylons have also been treated to some attention and are seemigly wider at the bottom following the McLaren trend (When viewed from the front). From the side the pylons also taper from the top down to their connection with the mainplane.
Moving along the car we can see that the Sidepods haven't been treated to a dramatic change in philosophy but the team have added a nice piece of detail on the floors edge. The Floor Scroll is detached from the floor itself bar a few a few connecting strakes and courtesy of F1_Aero over on twitter he explains that ' It's designed to increase the draw under the front of the floor and provide a stronger floor edge vortex for floor sealing'
On top the Sidepods the airflow is conditioned by the same elements used last season
Lastly we have the Monkey Seat which is fairly innocuous with the only real thing of design merit being the large perforation between the two wing sections it uses. It does however sit on a curved section of the Beam Wing which has been designed to allow air to pass between the Wing and Structure.
In summary just like all the launches that have preceded it the Red Bull car launch acted as a way of showing off commercial partners and so doesn't show it's hand, we must therefore wait til testing to truly see what they have up their sleeve.
