Active modular aerodynamic drag reduction system

摘要

Systems and methods for airflow control of a moving ground vehicle are provided. The system includes an actuator module and a sensor unit mounted on the vehicle, and a controller. The actuator module includes at least one synthetic jet actuator to generate a synthetic jet, to modify an airflow around the vehicle. The sensor unit includes at least one environment sensor to capture environmental sensor data proximate the vehicle. The controller receives the environmental sensor data from the sensor unit and determines at least one of a drive frequency and a drive amplitude for controlling the at least one synthetic jet actuator, based on the received environmental data.

1. A system for airflow control of a moving ground vehicle, the system comprising:
an actuator module, mounted on the vehicle, having at least one synthetic jet actuator configured to generate a synthetic jet, to modify an airflow around the vehicle; a sensor unit, mounted on the vehicle, having at least one environment sensor configured to capture environmental sensor data proximate the vehicle; a controller configured to receive the environmental sensor data from the sensor unit and to determine at least one of a drive frequency and a drive amplitude for controlling the at least one synthetic jet actuator, based on the received environmental data; and a power manager electrically coupled to the at least one synthetic jet actuator, the power manager configured to generate an oscillating voltage signal based on the at least one of the drive frequency and the drive amplitude determined by the controller, the oscillating voltage signal being used to drive the at least one synthetic jet actuator.
