Clean air is a much bigger advantage. It’s simple, it’s effective, and it’s one of the major ways open-wheel racing drivers get past each other. Throughout his life he was always told French was the language of romance, but it was English he fell in love with. I’m not sure if there is dirty air tbh, I think there is just slipstream and the reason you are running wide under braking and wide following a car mid turn maybe because slipstream is pulling you a bit faster bringing you closer to the limit during the turn, and the braking is cos your entering faster because of slipstream and bearing in mind your slipstreaming while your braking until the speed is low … However, it is inevitable that the car behind is still going to see some effect of the disrupted air by the leading car. A CFD simulation, courtesy of SimScale, showing the turbulent air coming off an F1 2022 car. When watching Formula 1 or other racing, we often hear commentators talk about ‘slipstream’ and ‘dirty air’ but what is the difference? This combination of deep aerodynamic optimisation and turbulent tyre wakes are why ‘dirty air’ is so much more detrimental to Formula One cars.As mentioned earlier, for 2021 (now 2022), the aero regulations aim to not only reduce the size of these wakes, but also suck this turbulent air inboard and then eject it up and over the car behind. But Chilvers is optimistically cautious about the new regulations, ‘I think these proposed regulations are certainly going to make a big difference. Nothing more, nothing less. And only on a long straight are you going to find any real benefit. Effectively, the two phenomena are the same, but the key difference lies in the part of the track at which it occurs. To make an analogy of it: imagine that you are running a race but the wind is against you. They are the same thing in different situations. ‘Typically, the driver will drive to the aero balance set up to make them feel comfortable and have the confidence to turn into a corner. ‘When drivers are following another car, they are pushing hard and pushing components like the engine and brakes to the limits,’ explains Chilvers. Aerodynamically, this means the aero balance,’ explains Chilvers. But this wake left behind by the lead car further exasperates the problem of dirty air for the following car.

All of that causes overheating of all of the systems and that is why the drivers have to generally back off just to manage those systems.While the term ‘slipstreaming’ is often mentioned in many forms of racing from NASCAR, GT, even to two-wheelers, it is less common to hear ‘dirty air’ mentioned in other forms of racing than Formula One.
Every issue provides unrivalled technical analysis of everything from World Championship series including Formula 1, to grass roots racing. About Us Advertise. 15th February 2018. With a passion for motorsport engineering, Alto now works as a design engineer for Cranfield Simulation; developing full motion motorsport simulators.Dirty air on the other hand occurs in the corners, where the cars are already in a grip limited condition. Subscribe on YouTube YouTube. This increases the vertical force on the tires and consequently generates more grip. Slipstream. “Slipstream” and “dirty air” are two terms that are often used in the context of high-downforce, open-wheel racing, but rarely outside of it. A loss in aero balance can occur as disrupted onset flow will affect the front wing first and causes a significant loss in performance and efficiency. “Slipstream” and “dirty air” are two terms that are often used in the context of high-downforce, open-wheel racing, but rarely outside of it. Clean air is when the air is ‘undisturbed’ and dirty air is when the air is ‘disturbed’ How do you ‘disturb’ air? ‘One of the biggest things that will upset the driver is the change in the ‘feeling’ of the car. Dirty air is bad while cornering but slipstream is when dirty air helps you go faster on the straights As well as that, you have to brake more due to the higher top speed, and your cooling suffers in the … … Due to this disruption in the onset flow, the following car has reduced aerodynamic performance. This is why F1 have worked hard to develop a While it may be curious that F1 cars are so drastically affected by this change in onset flow conditions, it can largely be explained by the level of aerodynamic optimisation that F1 teams are now able to achieve.
