Hello friends, today I am going to explain ‘How does venturi principle work’ on this car and its hidden aerodynamic features. Same technology was also used in Formula 1 once and will be used again. In order to preserve this magnificent look, designers didn’t want to use a huge wing. At the same time I will talk about Aston Martin’s hidden aerodynamics, this hidden, invisible control of air and ability to produce 180 kg of downforce. This magnificent car is Aston Martin DBS Superleggera And not to disturb this amazing look, some specific aerodynamic features are added to this car. The first one is pretty obvious. There is a huge grill in front of this car. The air enters from this huge grill. I will later explain what happens to this air later in the video. The real engineering related part is that part actually. But at the same time air enters from the front-side grills and flows trough the wheels. While flowing, it also cools down the brakes and exits from these special carbon fiber side vents. Obviously these vents look really good, but it looks even better when you open the hood It really is a masterpiece. The air left from these vents gets divided by the wing shaped side mirrors. This is all calculated. Majority of this divided air enters trough this vent and flows through body panels, and leaves through the wing called ‘air blade’. This air pushed perpendicular to the ground Now the important part is, what happens to the air entering through the main grill? That air flows beneath the car through venturi tunnels. Venturi tunnel is a duct with large opening, which gets smaller in a certain point causing the air to flow faster in that specific area. This is called venturi principle. Air moves with contant velocity in a regularly shaped duct. If you choke that air, as you can all imagine velocity of that air will increase. This is caused by mass continuity. This high velocity air would have low pressure due to Bernoulli principle. This low pressure area would cause low pressure below the car and higher pressure above the car. Higher pressure above the would push the car towards the ground, and produce downforce. At the same time air flowing beneath the car would flow through double-diffuser, again a Formula 1 technology, would connect with the air exiting air blade causing low drag forces acting on the car. And at the same time would produce downforce as I said. Venturi principle is one of the main subjects shown in fluid mechanics and these kinds of super cars by controlling the air flow, can produce downforce without sacrificing the clean look of the car. Once it was used and banned in Formula 1 because it was too advantageous But now, starting from 2021 it will be used again. This is all I explain in this video.
