The invention belongs to the technical field of vehicle drag reduction, and particularly relates to a vehicle drag reduction structure, a drag reduction method and a vehicle thereof. The vehicle drag reduction structure comprises a self-maintaining synthetic jet device arranged on the vehicle; air in front of and/or below the vehicle flows into an inlet of the self-sustaining synthetic jet device, so that incoming air flows enter the self-sustaining synthetic jet device, and meanwhile, low-speed air in front of and/or below the vehicle is sucked away; an outlet of the self-sustaining synthetic jet device ejects an air jet from the roof of the vehicle for injecting a high energy air fluid into the roof of the vehicle to inhibit flow separation at the roof of the vehicle. According to the vehicle resistance reduction structure, the incoming air flow is fully utilized, the air energy utilization rate is improved, the resistance reduction effect is improved in the two aspects of inflow of the incoming air flow and ejection of the air jet flow, and the vehicle resistance reduction structure is simple in arrangement and low in cost.

    本发明属于车辆减阻技术领域,具体是涉及到一种车辆减阻结构、减阻方法及其车辆,其中车辆减阻结构包括设置于车辆上的自维持合成射流装置;所述自维持合成射流装置的入口流入车辆的前方和/或下方的空气,以用于供空气来流进入至自维持合成射流装置,同时吸除车辆前方和/或下方的低速的空气;所述自维持合成射流装置的出口将空气射流从车辆的车顶喷出,以用于对车辆的车顶注入高能量空气流体,抑制车辆的车顶处的流动分离。本车辆减阻结构充分利用了空气来流,提高了空气能量使用率,通过空气来流的流入和空气射流的射出两方面提高减阻效果,而且车辆减阻结构布置简单,成本低。
