  • Underbody channel vortex generators
    Patent number: 10457341
    Abstract: A vehicle including a vehicle body having a first end and an opposing second end, wherein the first end is configured to face oncoming airflow. An underbody extending between the first and second ends of the vehicle body and the underbody including a first lateral edge, an opposing second lateral edge and a central region defined therebetween. At least one aerodynamic member on the underbody, the at least one aerodynamic member having at least one aerodynamic surface wherein the at least one aerodynamic surface includes at least one curved triangular channel configured to cause airflow to separate over a trip edge of the at least one curved triangular channel to create a low pressure vortex region within the curved triangular channel.
    Type: Grant
