Ferrari SF70H double monkey seat winglets in Sochi

Ferrari continues to test the different aerodynamic configurations on their SF70H with two winglets behind and above the center exhaust pipe which has several aerodynamic functions.

Ferrari is the only team that uses double rear wing support pillars, which is a bit unusuall because the single pillar has obvious aerodynamic advantages because it connects with the rear wing in just one place and hence less hinders its efficiency.

The Maranello team argues that their double holders are “significantly lighter” than single solutions used by every other team in F1 2017. Ferrari had to protect its double pillars with a gold foil to withstand the extremely high temperature of the central exhaust pipe passing between them. Gold is an extremely high heat capacity so teams often use golden foils in the engine and exhaust system area.

The technical rule in this area allows the use of 20 cm wide winglets, as last year, but this year they may be moved more behind, which Ferrari decided to exploit and presented a new, double winglet configuration in Russia.

One is located above the central exhaust pipe and consists of two curved elements that are connected to the edges by small side plates joining on each side of the rear wing holder and also being wrapped in gold foil.

The other winglet is located about twenty centimeters behind the first and is attached to the rear crash structure that is narrower than the wings itself. That wing consists of three elements to produce even more downforce, and it will benefit even more from the energy and speed of hot exhaust gases.

This wing also helps to connect the rear wing and diffuser airflow as it is located between them, but as any surface on the car it brings extra drag, especially the elements that produce downforce.

The position of the exhaust pipes has been strictly controlled by the rules since the teams in the period from 2010 to 2013 intensively used exhaust gases for aerodynamic purposes, and thereby spent the huge amount of money on that technology. It seems that Ferrari found a way to at least take slight advantage of the beneficial effect that the hot exhaust gases have in generating downforce.
