It is a widespread sight to see F1 vehicles weave behind the security automobile through the security automobile interval. The vehicles 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.
Nonetheless, there is a science behind all that. Drivers behind the security automobile swerve in a zig-zag movement, as they give the impression of being to maintain their automobile in good situation earlier than the security automobile restart. Listed here are a number of the advantages of F1 vehicles weaving behind a security automobile and why F1 drivers do it.
Why F1 drivers weave behind a security automobile
Right here’re a number of causes:
#1 To maintain the tyres in optimum temperature window
Probably the most essential elements for the efficiency of the automobile is the tyres which are in touch with the monitor floor. They must be saved within the optimum temperature window for greatest efficiency. If the tyres fall under the working temperature window, the grip is misplaced, and the motive force is not going to have the arrogance within the automobile to push it to its most.
If the tyres are too scorching and exceed the working vary, there shall be extreme thermal put on, decreased 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 through the security automobile interval, the tyre temperatures are monitored carefully, and drivers are saved 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 vehicles in entrance or defend from ones difficult the chief.
The zig zag motion tends to additionally assist in conserving 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 may trigger lockups and even incidents.
#2 Clear the particles that is likely to 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 outstanding as increasingly tyre rubber is laid down on that a part of the monitor in comparison with different components.
Consequently, 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 vehicles because the race progresses. Attributable to accrued particles on the edges of the monitor, at any time when an F1 driver goes off the racing payh (to both overtake one other automobile or makes a mistake), their tyres decide up all of the particles.
Any particles or dust on the tyres means a decreased floor space of contact between the monitor floor and tyre. A decreased floor space of contact means decreased grip whereas working. So, at any time when 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 through the security automobile restart.
#3 Burn off extreme gas
F1 vehicles have an higher restrict on the quantity of gas that must be utilized in a race. Not solely that, there’s an higher and decrease restrict on the gas movement fee that may very well be fed to the ability unit. One other added variable within the efficiency of an F1 automobile is the burden of gas.
Extra gas within the automobile tends to extend the burden of the automobile, resulting in longer lap time. Therefore, it is at all times a wonderful stability between the gas quantity in a automobile, gas movement fee and lack of efficiency attributable to weight of gas.
These variables are saved in thoughts when F1 vehicles are fuelled earlier than the race. Now, through the race, if there have been too many laps spent behind the security automobile, the automobile finally ends up having marginally extreme gas within the tank.
This extra gas may compromise lap time, so to burn it, F1 drivers are likely to weave in a zig-zag movement and convey the automobile again to optimum situations.
