Leaning Vehicle Side Suction for Tilted Downforce

The patent introduces actively controllable openings in the fairing that can be dynamically opened or closed based on vehicle tilt angle. When the vehicle is tilted, the openings are opened to allow airflow generation on the tilted side; when straight, they are closed. This dynamic adaptation enables the system to maintain effectiveness across different vehicle orientations, resolving the contradiction between straight-line and tilted downforce generation.

The patent applies downforce generation locally only where needed - specifically on the side of the vehicle that is tilted toward the ground. By using openings positioned on the fairing that can be selectively activated, the system creates localized airflow and pressure differentials only on the relevant side during cornering, rather than attempting to generate downforce symmetrically on both sides. This local quality approach optimizes downforce effectiveness in tilted positions.

The openings in the fairing are designed to be dynamically controllable, switching between open and closed states based on vehicle operation mode. During straight-line driving, the openings remain closed to preserve clean aerodynamics and minimize drag. During tilted/cornering operation, the openings are activated to generate suction and enhance downforce. This dynamic control eliminates the continuous aerodynamic penalty that would result from permanently open openings.

The system employs periodic or conditional activation of the openings based on vehicle tilt angle and cornering requirements. Rather than maintaining a constant state, the openings are activated only during the specific operational condition (tilted position) when they provide benefit, and deactivated during straight-line driving when they would harm aerodynamic performance. This periodic action pattern resolves the contradiction between the two operational states.

The system utilizes the vehicle's existing motion through air as the driving force for the flow-generating devices. Rather than requiring powerful independent motors or vacuum pumps, the design employs the relative airflow created by the vehicle's forward motion to drive fans or blowers that generate suction. This self-service approach leverages the operational condition (vehicle movement) to power the downforce enhancement system, minimizing the need for additional complex power transmission components.

The patent employs pneumatic principles by using airflow and pressure differentials as the primary mechanism for generating downforce. The flow-generating devices create controlled suction zones that manipulate air pressure distribution around the vehicle, particularly on the tilted side. This pneumatic approach avoids complex mechanical linkages or hydraulic systems, achieving the desired force enhancement through fluid dynamics with relatively simple device architecture.
