A huge thanks to Fuel For Fans for supporting the channel! Look at these strange vapour trails coming off the rear wing of these F1 cars. They are only visible in certain conditions but are present whenever the car is at speed. It’s the effect that enables flies to fly, and the Concorde to reach such high speeds. They are called Vortices, and are a natural bi-product of an F1 car’s wings. They produce a lot of drag and ultimately slow the cars down. ➤ Subscribe for more incredible motorsport: https://goo.gl/AbD2f9 So how do you create Vortices? This is actually easier to explain with a plane wing. As you probably know, a plane wing creates lift by using a low pressure area above the wing - this then literally sucks the plane upwards. You can see the low pressure area here, where the cloud-like vapour is above the wing. You’re only able to see this in certain conditions, but we will get to that. But the interesting thing is that at the edges, this creates a strange effect. The air here is able to spill around the edges of the wing, and so, the air from below the wing is sucked around the side by the lower pressure air. This creates a tumbling, turning effect - starting a spiral of air that creates a mini-tornado, that trails off the wing. This is what we call a vortex. For planes the vortices are a bad thing, they produce a lot of drag - but are often unavoidable as they are a natural bi-product of having a wing - and you need those. They are also naturally created on an F1 car. Back in the 80s and 90s, you could see them trailing off the rear wing, sometimes up to a metre long. The rear wing produces about 30% of the drag of an F1 car, and this is part of the reason. ➤Follow us on: ➤ Instagram- @official_driver61 - https://bit.ly/D61Insta ➤TikTok - @official_driver61 - https://bit.ly/D61TikTok 📺 F1 Driver’s Technique Explained ➤ Senna’s bizarre technique: https://bit.ly/3lORK59 ➤ How Schumacher’s style won 7 championships: https://bit.ly/3527cVz ➤ Alonso’s strange steering: https://bit.ly/2Z7a93v ➤ How Verstappen will be F1 champion: https://bit.ly/3jK6L6n ➤ How Verstappen is so fast in the wet: https://bit.ly/32WMVhr 📺 F1 Engineering ➤ How F1 brakes work: https://bit.ly/3h0Whh0 ➤ How an F1 clutch works: https://bit.ly/3i0oDJM ➤ What’s inside an F1 gearbox: https://bit.ly/2DzMqRW ➤ How F1 teams change four tyres in two seconds: https://bit.ly/2QVpkIl 🏎️ Track & Racing Driver! ➤ Get a free report on your track driving: http://bit.ly/2LmYNBA ➤ Get faster on track with our FREE 25-part tutorial series:http://bit.ly/2PypIMK ➤ Our real-world training programmes: http://bit.ly/2ktjtgV 🏁 Sim Racers! ➤ My sim wheel: https://bit.ly/354BBlY ➤ My sim pedals: https://bit.ly/3eJckQo ➤ Our sim racing course: https://bit.ly/34WuV7p ➤ Get a free report on your track driving: http://bit.ly/2LmYNBA ➤ Driver61 Sim Racing Channel: http://bit.ly/2BMdk4B #Formula1 #Aerodynamics #Engineering 00:00 Vortex - An Aerodynamic Accident 00:39 How Vortices Are Created 01:33 How Vortices Affect F1 Cars 02:00 F1 Engineers - The Last Airbenders 02:45 Deliberate Vortices 03:44 Rear Wing Vortices 04:30 Genius Aero Trickery 05:13 Fuel For Fans Black Friday Sale! 06:40 Do Vortices Make a Difference? 06:40 Why Can Only See Them In Certain Conditions?
