It is a widespread sight to see F1 automobiles weave behind the security automobile throughout the security automobile interval. The automobiles are sometimes seen swerving in a zig-zag movement behind a security automobile, and for a brand new fan, that doesn’t make sense in any way.
Nevertheless, there is a science behind all that. Drivers behind the security automobile swerve in a zig-zag movement, as they appear to maintain their automobile in good situation earlier than the security automobile restart. Listed here are a number of the advantages of F1 automobiles weaving behind a security automobile and why F1 drivers do it.
Why F1 drivers weave behind a security automobile
Right here’re a couple of causes:
#1 To maintain the tyres in optimum temperature window
One of the essential elements for the efficiency of the automobile is the tyres which are in touch with the monitor floor. They have to be stored within the optimum temperature window for finest efficiency. If the tyres fall under the working temperature window, the grip is misplaced, and the driving force won’t have the arrogance within the automobile to push it to its most.
If the tyres are too scorching and exceed the working vary, there might be extreme thermal put on, diminished tyre life and shortened race stint. To exacerbate issues, the efficiency extracted from the tyre wouldn’t be optimum too.
That is exactly why at each stage of the race, not solely throughout the security automobile interval, the tyre temperatures are monitored carefully, and drivers are stored knowledgeable. Throughout a security automobile interval, that turns into much more essential, as the sector is bunched collectively. If the tyres are within the working vary, one can assault the automobiles in entrance or defend from ones difficult the chief.
The zig zag motion tends to additionally assist in protecting the brake temperature optimum, as more often than not the primary nook of a race monitor is a heavy breaking zone. If the brakes are lower than temperature, it might trigger lockups and even incidents.
#2 Clear the particles that could be on the tyres
One of many largest considerations throughout a race is the formation of a racing line on the monitor. A racing line is the optimum path for an F1 automobile throughout the monitor. Because the F1 race weekend progresses, the racing line turns into increasingly more outstanding as increasingly more tyre rubber is laid down on that a part of the monitor in comparison with different components.
In consequence, throughout a race, this half tends to be the extra cleaner a part of the monitor and has extra grip. The opposite half tends to be considerably soiled with all of the tyre rubber falling off the automobiles because the race progresses. As a result of collected particles on the perimeters of the monitor, every time an F1 driver goes off the racing payh (to both overtake one other automobile or makes a mistake), their tyres choose up all of the particles.
Any particles or dust on the tyres means a diminished floor space of contact between the monitor floor and tyre. A diminished floor space of contact means diminished grip whereas working. So, every time there is a security automobile, a driver weaves in his automobile to take away any particles on the tyres in order that the automobile would have optimum grip throughout the security automobile restart.
#3 Burn off extreme gasoline
F1 automobiles have an higher restrict on the quantity of gasoline that must be utilized in a race. Not solely that, there’s an higher and decrease restrict on the gasoline stream fee that could possibly be fed to the facility unit. One other added variable within the efficiency of an F1 automobile is the burden of gasoline.
Extra gasoline within the automobile tends to extend the burden of the automobile, resulting in longer lap time. Therefore, it is all the time a superb steadiness between the gasoline quantity in a automobile, gasoline stream fee and lack of efficiency as a result of weight of gasoline.
These variables are stored in thoughts when F1 automobiles are fuelled earlier than the race. Now, throughout the race, if there have been too many laps spent behind the security automobile, the automobile finally ends up having marginally extreme gasoline within the tank.
This extra gasoline might compromise lap time, so to burn it, F1 drivers are likely to weave in a zig-zag movement and produce the automobile again to optimum circumstances.
