At the beginning of this month, Ducati posted a promo video for its new Panigale V4 superbike. The video shows the new machine testing in a wind tunnel, touting the tagline that the motorcycle was “shaped by the wind.”
Surely this access to a high-speed wind tunnel for development purposes is the byproduct and one of the benefits of Ducati being part of the Volkswagen Group.
Though, computational fluid dynamics (CFD) has all but made wind tunnels obsolete, making such things more of a show of engineering, and thus marketing. We digress.
What is of note though in this video, however, beyond the interesting glimpses of Ducati’s physical fluidic analysis, is that it is a glimpse at one of the Panigale V4’s very early designs.
BMW Motorrad Goldbet SBK’s Chaz Davies had some homework ahead of this weekend’s World Superbike round in Monza, as the Welshman spent time in BMW’s high-speed wind tunnel to work on his aerodynamics with the BMW S1000RR. With Monza being one of the fastest courses on the WSBK calendar, a rider’s ability to have the optimal body position down the the track’s long sections, where speeds can easily exceed 200 mph, is a crucial element to race-day success.
“It was a really interesting afternoon”, said Davies. “When testing on a track, you try new development parts and different settings but you are not working on your body. So it was great to experience in a stable environment with my riding position, to move myself around on the bike, to have elbows and shoulders in different positions and to then see in the data what difference it makes.
As the BMW World Superbike team prepares for the 2011 season, Leon Haslam and Troy Corser took a break from their training regiment to spend some time in BMW’s wind tunnel facility in Bavaria. Looking to hone the maximum performance out of the S1000RR, both riders worked on their optimal streamlined body positions in speeds up to 150 mph. The BMW WSBK team also looked at the S1000RR’s fairing, examining how to optimize the bike’s Cx or coefficient of drag (we assume any modifications that were made were WSBK legal of course).
The team will get to test its results later this month in Jerez, and in the meantime Haslam and Corser will be shipped off to a BMW fitness training bootcamp with fellow BMW riders James Toseland and Ayrton Badovini from the BMW Italia squad, along with members of the BMW Enduro team. We don’t like the sound of this training camp, but BMW has given us 12 high-quality shots of the S1000RR in the wind tunnel, which we enjoyed.
After a lively discussion on fully-faired motorcycles in his original post, including a lengthy post by Craig Vetter, Michael Czysz follows up the discussion by further delving into streamlining, dustbins, and the difference between the two. In his discussion Czysz explains the purpose and benefit of taking aerodynamics into account not only in electric racing but also in ICE applications, and then walks us through its use on the MotoCzysz C1. The post is a good primer on the exponential force that streamlining tries to overcome, and well worth a read for that purpose. Michael Czysz closes his post with a hint that he’ll have a dustbin at the ready should the field warrant such a fairing, and should his rider Mark Miller feel comfortable using it.
