Olympic track-cycling is the world where hundredths of seconds separate the worst from the best. Living under the pressure from knowing that one bad movement can decide about the whole race is something you will eventually learn to live with. But having such mindset forces you to seek perfection, and to constantly try to improve one tiny step by step. Now, \u0160koda AUTO helped the Czech Olympic cyclist Pavel Kelemen to make one of these steps towards excellence by using the same technology\u00a0that is usually reserved only for development of new top secret car models. This is a story of how you make an aerodynamic analysis of a cyclist.<\/strong><\/p>\n<\/lite-youtube>\n

In the beginning there is this exceptionally talented young man who is known for being blessed with perfect muscle structure and great passion for cycling. We kept thinking how to help him because, to be honest, track-cycling is not one of the promoted sports in his homeland. And then we realized that a few of his competitors had been using advanced CFD simulations\u00a0and wind-tunnel aerodynamic tests to improve their posture, seat position, and bike setting. Something that is far from common in the cycling world but we had the technology at our fingertips. With professionals just around the corner and all the computing power down in the basement we asked ourselves the question \u2013 why not? We should give him all the data he needs, which would help him, hopefully.<\/p>\n

\"IMG_1305-lens-corection<\/p>\n

First, we had to make a 3-dimensional\u00a0digital model of Pavel, without which we wouldn\u2019t be able to feed the data to the computer. We took 115 perfectly coordinated cameras to take Pavel\u2019s pictures from every possible angle \u2013 that was our starting point. But it sounds easier than it actually was. Reflections off his helmet, moving legs, and shiny materials \u2013 none of these things were making the job easier but we had everything we needed at the end of the day.<\/p>\n

Before the math could even start all the photos had to be converted to a basic 3D model and then to a much more complicated and tweaked one. From this point the guys from \u0160koda AUTO aerodynamics department took over and started to work the magic. The time for which they were torturing the computers and trying several possible postures seemed to be endless because we were so excited and curious about the results. When they finally called back we all decided to present Pavel with everything in person. So, we hopped into the car and went to Vienna. By the way, did we mention that there is no proper track in the Czech Republic, so Pavel and his team mates have to train in Austria?<\/p>\n

It was great to spend a day with\u00a0coach Petr Klime\u0161 on Ferry-Dusika-Hallenstadion in Vienna. It had everything – spirit, passion and enthusiasm, and that feeling of respect you have when you meet someone who had truly accomplished something significant. But what about the results, right? The CFD simulation\u00a0showed that there is a possibility of improvement on many levels, including Pavel\u2019s helmet, and the posture of shins, hips, arms, and calves. The bike seemed to be set perfectly but we were able to give him one or two tips on how to treat his wheels for lower aerodynamic drag. For Petr Klime\u0161 it was\u00a0the\u00a0first opportunity to actually see how the\u00a0air flow\u00a0looks and behaves. Although in theory, he seemed to know everything about it. It was great to see him constantly discussing all the possibilities over and over, with a gleam in his eye while ticking between the computer screen and the experts.<\/p>\n

Now you have to know that this is not a one-off thing. It\u2019s just not enough to tell someone how to control air flow separation and then never talk to him again. There is much more work to be done, many variables to be taken into account, and a new friendship to be maintained. And hopefully, all this will help one young man to stand on the Olympic podium.<\/p>\n","protected":false},"excerpt":{"rendered":"
