Red Bull RB10 - 'S-duct' packaging 26 February 2014

One of the most intriguing design aspects on Red Bull's 2014 car, the RB10, is its nose, which features an evolution of the 'S-duct' seen on last year's RB9 (but first introduced by Sauber in 2012). This clever concept has become even more important this year in order to reduce the lift tendency and airflow separation that are byproducts of the low nose/stepped chassis combination. The blue arrows in this drawing indicate the pathway of air through the car. As you can see, air enters through ducts on the nose and underneath the chassis, passing through in the bulkhead area, and then exiting via a duct on the top of the chassis. This year's solution (main drawing and right-hand inset) is much better packaged than 2013's (top drawing and inset), as the brake fluid cylinders are no longer squeezed behind a fairing, but rather placed in front of the fairing.
