2018 FIFA World Cup Russia Telstar Official Match Ball: A throwback to the classic Telstar ball used during the tournament in 1970, the 2018 version features a thermally bonded six-panel design to maximize flight and pace with pixilated detailing for a modern aesthetic. The 2018 official match ball also comes with an Interactive Near Field Communication (NFC) chip that allows you to interact with the ball through your smartphone.
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.
