Aerodynamic Study of MotoGP Motorcycle Flow Redirectors

In recent years, the introduction of aerodynamic appendages and study their performance in MotoGP motorcycles has increased exponentially. It was 2016, with single electronic control unit, that search began for alternative methods to generate downforce were not solely reliant on motorcycle’s electronics. Since then, all types spoilers, fins wings have been observed fairings motorcycles. The latest breakthrough Ducati’s implementation flow redirectors at front bottom fairing. aim present test two hypotheses regarding redirector by responding corresponding research questions its function advantage, both straight leaning position. a preanalytical cognitive act, visual conducted and, accordingly, 3D-CAD model designed ad hoc compliance FIM 2022 regulations motorcycle redirector. Numerical simulations using OpenFOAM software then carried out analysis. Finally, Taguchi methodology applied as an effective simulation-based strategy narrow down combinations geometric parameters, reduce solution space, optimize number simulations, statistically analyse results. is highly dependent inlet when results indicate models leaned bearing redirector, regardless geometry, appendage generates minimal increment drag coefficient. cornering situation, separator reduces disadvantageous influence wheel rotation “diffuser effect” drawing towards outside curve, creating extra downforce.
