Aerodynamics tests The windtunnel gives some useful insights into the test wheels’ aerodynamic performance. Drag measured in the wind tunnel is a reasonable indicator of the wake generated behind the wheel. The drag is an essential value. It is meaured by strain gauges bonded onto the inverted fork that holds the tested wheel. These gauges … Lire la suite de Great wheel test 2008 – Part 1 – Aerodynamics
