They have the same thing with Formula 1, but they don't show it on TV. It's an interactive Computer-aided Fluid Dynamics simulation. In its lowest setting, such as here, it can do real time calculations and overlay graphics. At highest settings, it takes about 10 minutes to simulate every single atom of air going over the surface of a vehicle. There is a reason that Lenovo, Hewlett-Packard, etc, are partners with a LOT of motorsports and powersports teams, as the computing grunt needed for CFD is massive. It has improved drastically over the past two years, however, with the release of real-time ray tracing GPUs, which, when set up with error-correcting memory and in special cards (Radeon Pro, nVdia Quadro), they can do CFD and RT in real time, which is what I think was happening here. Notice the bike is also locked hard in place, so it was probably overlaid a 3D simulation of it in that 3D space, so the graphics align
thank you, highly appreciated. The animation is based on a high res CFD, which was done by the aerodynamics team of Ducati Corse. The particles are emitted from a virtual smoke rack which is either controlled by Gigi using a 3D tracker or at a fixed position. Pecco and the Desmo are real, but have virtual counter parts needed for occlusion. The bike can move, as it can be tracked as well. A steady cam is fitted with a redspy to allow for precise camera tracking and unlimited freedom. Animating and rendering the particles is done in realtime using Viz Engine 4 on an RTX A6000 inside a Lenovo P620. Compositing is also done in real time using the same software and hardware with very little latency so Gigi and the camera man get instead feedback.
Believe this or not. More than 15 years ago on a popular international Motogp forum I asked why aerodynamics were not employed on MotoGP motorcycles. At the time I was not only a rider, but an F1 fan as well. It made sense to me that with the machines capable of going over 200mph, it would be beneficial to make onrushing air your friend instead of your enemy. I was told at the time by the forum "experts" that it was not possible and was a silly idea! Lol - here we are 15+ years later and aerodynamics are an accepted part of MotoGP machines.
But they really haven't changed much. OK we added 'wings' and the rear tire scoop but that's about it. Well i guess you could throw in the humped suit too. But the bikes haven't changed much. Aero had been apart of racing for a long time. We had full fairings back in the '50s but were banned/limited because of side wind issues. Race bikes with fairings was common back in the '70s. The design of the Hayabusa was odd and new because it was developed in the wind tunnel testing back in the '90's. Riders have been tucking behind fairings and handle bars for almost a 100 yrs. Testing in wind tunnels at least 50 yrs. So being wind friendly is not a new concept imho. I wouldn't be surprised if the experts on the forum you speak of weren't self declared experts. Another thing, teams that were doing testing and making small discoveries and implementing changes may play it down a wee bit as to not reveal their progress. I think you were 'punked' (and gullible)....sorry.
what about in tracks like Assen or Australia, is it really that useful in slow speed corners? And you said "beneficial". Like there's no compromise when you put those ugly stuff and it just "magically" benefits the bike in all scenarios? I do wonder though, why not go all the way through! why not try active and passive aero for the bike!
Taking advantage of aerodynamics in MotoGP in the same way they do in F1 its still not possible. The reason why F1 laptimes are like 30% faster then Motogp is because with those massive wings they can pull of 4, 5, even 6 g's of acceleration, but bikes LEAN when they corner, therefore a fixed wing pushing down when the bike is straight will push partially down and partially to the outside when the bike is leaned for cornering, effectively nullifying the extra grip it provides.
When I saw the first pictures of the 2021 bike, I was thinking they've worked on that while the bike is in the leaned over position. 8:24 they've taken that lower wing off for this presentation too.
When watch the new technique from Rossi before cornering, I am thinking…Why don’t add a “Wing” on the suit? Just add a triangular elastic fibre wing behind the knee, thigh and calf. That should increase the surface area for decreasing the speed. And during the straight line, the extra wing acts like an aerodynamic side wing? It’s only my thought…
I'm guessing the next logical step in MOTOGP is to start working on the inclusion of Air Breaks. By using pop out fins as per break input. Or....rotating winglets 😉 and the side fairing opening slightly like a butterfly 🦋
Not viable, as it can not be actuated by an electric or a hydraulic system. Aka active aero components are banned in MotoGP. The biggest air brake they have is the rider himself, and the carbon brakes do a good enough job anyway.
@@Dinara1up good to know 🙂 thank you Wingless were illegal in the beginning...they became legal eventually. What's ban now...may be the next step of evolution 👀 Look at street Hawk 😉
Awesome awesome video. That live CFD simulation was mind boggling, I'm still trying to figure out how they did it! Not a fan of Ducati bikes due to their looks but can say they're very functional machines!
Basically its Augmented Reality, the LED acts as a Wand. Just like how it works with VR, it maps the room for obstacles(bike, rider, & everything within set-visible area), this is the pass-through(see-through) vision of it, or Augmented Reality, because all they're allowing to show(on video) is the CFD live feedback as Overlay. The LED is infrared.
Hopefully someday there is some kind of DRS on motogp bikes, like maybe they open up the winglets on the straights and close it to an angle while entering and exiting the corners to optimize downforce
I think the point of F1 having DRS is to overcome the effect of dirty air in the corners. As long as there's not much dirty air in MotoGP, slipstream is enough.
I wonder if the wings start to cause a problem when the bike is at a very extreme lean angle? Surely the down force created at the front wheel would tend to push the bike sideways rather than downwards. Perhaps it is the relatively low speeds involved at extremely lean angles that makes this not a problem?
however dirty air produced by the aero package could cause major issue for rider/driver behind. we have seen it with pecco, martin lately. i believe f1 have abandoned this and moved into ground floor effect for a good reason
I'd like to know about how it changes as the bike turns over (the roll). It seems like a whole other dimension, being used to thinking of aero in terms of autoracing, where the thing stays straight up and down, hopefully no roll. What a mindf**k!?! Like, as the bike leans over, the angles of those wings relative to the level ground changes. But do you want the DF perpendicular to the track or along the angle of the bike? And how even useful is it in smooshing the bike into fast corners?
@@gokulkrishm51 yes, but he can only do that with "better" ducati. Casey still can win 3 times in 2010 season with a trash. Iannone has more potential... inconsistency was the problem
Pretty cool! Unfortunately CFD cannot give the full picture. That is why successful aircraft use known airfoil designs. What is really happening nobody really knows. A return to the mid 50's Moto Guzzi "dust bin" fairing would clean up a lot of eddies and vortices. And make the bikes trickier to ride.
Yes, they did like in F1. They didn't want to show the 2021 bike with the new "aero deflectors". Very clever from Ducati but kinda sad not to know how and what are they really used for.
The reason why ducati can play around aerodynamics and put as much wings on their bikes as they want to is because they have the most powerful bike on the grid.
Are active aerodynamics, moving wings, etc., allowed in MotoGP? Only a matter of time before we see dynamically and electronically controlled wings in MotoGP. 😉
