The soccer is the world's most popular and widely watched game. Due to increasing technological advancement and demand for performance, the ball manufacturers have been developing new designs progressively. A traditional spherical football made of 32 leather panels stitched together in 1970s has become only 14 synthetic curved panels thermally bonded without stitches ball in 2006 and more recently 8 panels football in 2010. Despite being most popular game in the world, scan data is available on aerodynamic properties of footballs especially Jabulani, Teamgeist and Fevernova balls. The primary objectives of this study were to evaluate aerodynamic performances of these three soccer balls. The aerodynamic forces and moments were measured experimentally for a range of wind speeds. The aerodynamic forces and their non-dimensional coefficients were determined and compared.
I read a few bad reviews on here but I didn't think the ball will be that bad. I had this ball for just a week! It looked great in the box but it's a very low quality soccer ball. It got deflated after hitting the post. There were marks and slits left on it after everything it hit. Might be good for kids but if you play soccer on a high level, you're really wasting your money buying this.
Despite the similarities with the Brazuca, the few differences between this ball and what players have gotten used to over the last four years will have an impact on play, says Firoz Alam, an aerodynamics engineer at the Royal Melbourne Institute of Technology in Australia, who has also performed wind tunnel tests on the Telstar 18. “When the player is making a short pass, they have to push a little harder, because at less then 60 kilometers per hour [or 37 miles per hour]it has more flight resistance than the Brazuca,” says Alam. The mid-range passes and corner kicks that gave the Jabulani so much trouble have been resolved. Compared to the Brazuca, the Telstar 18 is also more aerodynamically efficient in the 40-50 mile an hour range, so Alam says players will actually have to kick a little softer or they’re likely to overshoot. Over 55 miles an hour the two balls will feel very similar.
Whether it was a size 3, 4, or 5, we found that the Adidas Starlancer performed as it should. This allows beginning players at any age to begin getting a feel for what it is like to have the ball at their feet. There are two color options that come with the Starlancer as well and each performs as it should. For normal passing, crossing, and shooting drills, we found this soccer ball to be true to form. The machine stitching is strong and offers a fairly long lasting performance.
Although the length of kick may end up being a little shorter, the changes make the Telstar 18 more balanced, says Alam. On other balls, Alam and his team have found that there is a difference in how the ball flies based on where it’s kicked in relation to the seams. His tests have found that the Telstar 18 ball doesn’t have as much variation. The total length of seam of the Telstar 18 is 14.1 feet, 3.28 feet more than on the Brazuca. With the longer seam, and more symmetric panels, no matter how the ball is turned there is the same amount of seam exposed. “The other two balls were not like that, they were significantly different,” he says.
These soccer balls are exact replicas of the finale game balls, right on down to the specific design details that can be found on the ball. If you’re looking for a durable, reliable ball that can help players replicated the feeling of playing the game at home, then the Top Training Series by Adidas is one of the best options to consider today. Each ball is guaranteed to pass FIFA tests for weight, circumference, rebound, and water absorption. It is the closest you can get in the entry-level categories for a soccer ball to the match ball experience. https://www.youtube.com/watch?v=3OKagE2ZIRA
