Formula One's ‘Shark Fins’ Explained — Its All About The Corners
The shark fin or airbox sail was introduced by Red Bull back in 2008 on their RB4 machine.
For the 2017 Formula One season there are significant regulation changes and to meet them the cars now feature 'shark fin' wings. The shark fin inspired design can be seen on newly unveiled F1 cars along the top edge of their engine covers.
The new regulation changes have made the return of the shark fin and lower and wider rear wings. In 2016, the wing was 950mm high and 750mm wide. This season the respective figures are 800mm and 950mm in height and width respectively.
So the lower and wider rear wing on most of the cars will suffer more from the turbulence generated by air coming off the front axle and suspension. The solution for this was shark fin, or technically we can call it ‘airbox sail'.
The airbox sail was introduced by Red Bull back in 2008 on their RB4 machine. The long shark fin along the top edge of the engine cover helps to divert turbulent air away from the rear wing, especially while cornering.
Another use of the shark fin is for stability while taking the corners at tremendous speeds. The FIA has claimed that the 2017 Formula One cars will be lapping up to three seconds faster than last year's cars.
So comparisons between both the machines will be made from the first race of the season, both regarding pace and cornering speed. With the changes to the body such as wider front and rear wings and large tyres. One thing is clear that the new car's pace will come through cornering speeds.
