    • A drag reduction method and apparatus for reducing aerodynamic pressure drag associated with a vehicle in motion by use of substrates that can perform as turbulators. The substrates can have a texture that increase the momentum of the air in the boundary layer about a vehicle, moving separation points, and reducing low pressure areas thereby improving the fuel economy of the vehicle. The substrate can reduce the effects of the pressure drag by creating a turbulent boundary layer over the surface of the vehicle, moving separation points downstream where they produce less drag on the vehicle. An automated turbulator deployment system is also disclosed that provides improved aesthetics and can tailor the aerodynamic profile of a vehicle based on the current aerodynamic conditions.
    • 一种减阻方法和装置,用于通过使用能够作为湍流器执行的衬底来减少与运动中的车辆相关的气动压力阻力。 基板可以具有增加围绕车辆的边界层中的空气的动量,移动分离点和减少低压区域的结构,从而提高车辆的燃料经济性。 衬底可以通过在车辆表面上产生湍流边界层来减小压力阻力的影响,移动下游的分离点,在那里它们在车辆上产生较少的阻力。 还公开了一种自动化湍流器部署系统,其提供改善的美观性并且可以基于当前的空气动力学条件来定制车辆的空气动力学特性。
