DUCATI WORLD PREMIÈRE 2023

Aerodynamics

Les ailes ont été développées pour le Streetfighter V4 dans une configuration biplan conçue par les spécialistes de Ducati Corse en collaboration avec le Centro Stile Ducati. Elles assurent une stabilité maximale à haute vitesse et au freinage, elles permettent d'éviter la tendance au wheeling lors de l'accélération, limitant les interventions sur le châssis pour offrir un comportement agile et rapide en conditions mixtes.

Le développement aérodynamique a été réalisé entièrement avec des simulations CFD (Computational Fluid Dynamics) en utilisant une méthode de calcul qui implique des simulations stationnaires des champs de mouvement et de pression dans le but d'augmenter la force verticale sur le véhicule, en particulier sur la roue avant.

Aerodynamic appendages

To ensure maximum stability both at high speeds and when braking and a lower tendency to wheelie during acceleration, limiting as much as possible the interventions on the chassis..

Mudguards

The new fenders provide 35 kg (+ 7 kg) of "downforce" at 270 km/h, including 27 kg on the front wheel and 8 kg on the rear

Increasing the "anti-squat" effect

As on the Panigale V4, the swingarm pivot of the 2023 Streetfighter V4 is positioned .16 in (4 mm) higher, increasing the anti-squat action that helps the rider with greater stability, precision, and the ability to maintain the trajectory in all acceleration situations.

Increased support under braking and cornering

Increased support in haste and cornering is provided by both the new ergonomic shape of the fuel tank and the increase in its capacity (+ 0.5 liters).

Biplane wings by Ducati Corse

To reduce the lateral dimensions of the appendages as much as possible, it was decided to develop an aerodynamic configuration that provides two wings of reduced opening positioned in the shape of a biplane with the aim of making them work independently. The single appendage can be described as a wing with a single element and a rectangular plan, equipped with a winglet on the external lateral end. The wings have been positioned as close as possible to the front wheel (near the side radiator panels) to maximize the anti-wheelie effect.

How they work

The vertical load generated by the wings reduces the "buoyancy" of the front wheel at high speeds, the tendency to wheelie and increases stability during braking, entry, and cornering.

This dynamic behavior instils safety and limits the intervention of the electronic controls, so that the rider is led to keep the throttle open for longer as well as to brake later right into the corner, benefitting in terms of performance.

What are the benefits

The effect of the introduction of the aerodynamic appendages is 28 kg of downforce at 270 km / h, of which 20 kg on the front wheel and 8 kg on the rear wheel. The wings also give benefits in terms of heat loss by increasing the speed of passage through the water and oil radiators, respectively by + 2% and + 10%.
