Ferrari SF70H S-duct system revealed

Unlike in pre-season testing when the team were hiding technical details on their new cars, in Australia they are no longer allowed to use the screens to hide their cars from prying eyes and photographers’ lenses. Ferrari unique S-duct system was revealed with unique intersecting channels.

S-duct system captures the air underneath the nose (or on its sides) and forwards it on the upper surface of the monocoque and thus helps the airflow to stay attached to the upper surface. In Formula 1-duct system is used for years, but it has passed an inevitable evolution process, becoming more effective and efficient every year.

Good solutions in Formula 1 are traditionally copied so this year most teams used the S-duct system inlets positioned on the sides of the nose, which Mercedes used last year and Ferrari uses a similar principle on the new SF70H.

But Ferrari uses slightly different solution with S-duct system channels intersecting inside the nose so airsflow travs at less severe contour within the channel and thus can exit with greater speed on the upper surface of the monocoque.

Ferrari captures the air from sides (at certain angle) so these channels allow the airflow to travel faster on the top surface.
