Beschreibung
The bike aero tool offers a novel way to validate real racetrack measurements with a focus on aerodynamics. The method does not require any extra test equipment in order to obtain key findings for the evaluation of developments. It thus supports engineers and athletes at the racetrack and creates a link to established development tools.
When I started working at MotoGP Factory Racing Team in 2014, Aerodynamics was a relatively unexplored field. Therefore, an aerodynamic development process was built using state of the art tools like numerical flow simulations, wind tunnel tests and special on-track measurement equipment.But although using all these state-of-the-art tools, it happens not rarely, that new developments were not showing the expected positive effect on the racetrack. The reasons for this were manifold: changing track conditions, varying rider and tire performance or different environmental conditions.The bike aero tool was introduced to help engineers and athletes in the development of racebikes. A new approach for the assessment of aerodynamic racebike characteristics from real racetrack measurements was implemented - the so-called AIM approach, where AIM is the abbreviation for Aerodynamic, Inertia and Mass.A new quantity chi was introduced as representation of the high dynamic of a racebike and rider system on a racetrack, where the rider plays an important role in terms of its riding style. The riding style has a huge impact on the center of gravity position of the overall racebike and rider system as well as on the aerodynamics of the overall racebike and rider system.
