Abstract: A modular aerodynamic system for a vehicle includes multiple nozzles that generate airsheets. The airflow from the nozzles may be controlled separately. Thus, the nozzles collectively enable granular control of the overall air velocity profile around (e.g., behind) the vehicle. The airsheet configuration may allow the system to control the wake behind the vehicle for various purposes, such as drag reduction, stabilization, and/or breaking. The overall air velocity profile may increase the back pressure of the vehicle, reducing energy consumption. The system may also move the center of pressure and changing the dynamic response of the vehicle to other external forces. These changes may be implemented dynamically in response to aerodynamic/dynamic changes.
