7 AERODYNAMICS The Supertech R10 helmet has been developed in a full-scale wind tunnel from the outset of its development. Aerodynamic targets for coefficient of drag in different head positions, as well as stability at different angles, were a primary goal in the helmet shape development, first extensively developed with Computational Fluid Dynamics, then validated in a full-scale wind tunnel and finally on track. The result is S-R10, a helmet that achieves the lowest level of drag, and the highest level of aerodynamic stability at high speeds. Road riders will benefit from this too with reduced strain on their neck at high speed and low levels of wind noise. The S-R10 comes with two separate aerodynamic spoilers – a standard, and longer race version – and they’re both fitted with Alpinestars patented release system, with elastic joints that help the spoiler detach from the helmet shell if it is subjected to a significant impact. There are also lateral winglets to further support the helmet’s stability and improve aerodynamic drag. In addition, the helmet visor has turbulators to improve aero-acoustic performance. As a result, compared to the aerodynamic performance of the helmet in the standard set-up, the configuration with the race spoiler and aero winglets reduces drag by an additional 4.54%.
