Horiba MIRA has launched a dedicated aerodynamics database providing wind tunnel measurements on passenger cars and light commercial vehicles.
The Aero-Data website features data from more than eight years of independent testing in Horiba MIRA’s full-scale wind tunnel, of more than 50 vehicles.
In addition to recording standard forces and moments, Horiba MIRA has accurately measured the frontal area of each vehicle, rather than using a nominal reference area; this enables the accurate calculation of each vehicle’s drag coefficient – a key measure of aerodynamic efficiency.
The data can be harnessed to develop an understanding of current and future performance trends, to quantify competitiveness when new vehicles are launched into global markets, as well as ensuring design targets are achievable.
Traditionally, aerodynamic data from different vehicle manufacturers has not been directly comparable, due to differences in wind tunnel design and variations in testing methods, which can lead to noticeably different results.
In contrast, by testing all the vehicles in the database in the same wind tunnel facility and using consistent procedures, direct and accurate comparisons can be made between vehicles. This ensures vehicle manufacturers have the data needed to research new vehicle programs.
