Racing derived aerodynamics


For the Streetfighter V4 were developed wings in biplane configuration designed by specialists of Ducati Corse in collaboration with the Ducati Style Center, ensuring maximum stability both at high speeds and in braking and a lower tendency to accelerate, limiting as much as possible interventions on the cyclist, so as to have an agile and fast behavior in the mix.

The aerodynamics were developed using CFD (Computational Fluid Dynamics) simulation. The calculation method involved stationary simulation of flow and pressure to achieve increased downforce, especially on the front wheel.

To reduce lateral protrusion as much as possible, the aerodynamics team decided to adopt a 'biplane' configuration of limited 'wingspan' with upper and lower wings working independently.

Each appendage can be described as a square-plan mono-wing with a winglet on its outer tip. Moreover, the wings have been positioned as close as possible to the front wheel (near the radiator side panels) to maximise the anti wheel-up effect.

These aerodynamic appendages generate 28 kg of downforce at 270 kph (20 kg on the front wheel, 8 kg on the rear). The wings also help draw heat off the engine by increasing water and oil radiator throughflow speeds by 2% and 10% respectively.

Wing-generated downforce attenuates front wheel 'floating' at high speed and the tendency to wheel-up. It also improves stability during braking at the turn-in point and through the corner.

The aerodynamics thus instil confidence and limit intervention by electronic controls. This helps the rider keep the throttle open longer and brake later going into the bends, providing significant performance benefits.

The low front and forward stretch, to continue the charged lines of the tank, give the Streetfighter V4 a predatory look ready to attack.
