The invention provides a rail train and a jet flow control method applied to a windshield area of the rail train, and relates to the technical field of rail vehicles. The rail train comprises a train body, an outer windshield is arranged on the end face of the train body, and the rail train further comprises a jet flow device. The jet flow device comprises an air blowing unit, the air blowing unit is arranged on the end face of the vehicle body and located on the periphery of the outer windshield, and the air blowing direction of the air blowing unit is parallel to the length direction of the vehicle body and faces the end face of the vehicle body on the opposite side. According to the rail train and the jet flow control method applied to the windshield area of the rail train, in the advancing process of the rail train, the airflow blown out by the air blowing unit forms the airflow layer in smooth transition with the peripheral face of the train body between the two adjacent train bodies, the airflow on the periphery of the train body is induced to flow along the airflow layer, and the air flow in the windshield area of the rail train is controlled. And the aerodynamic performance of the windshield area of the rail train is improved.

    本发明提供一种轨道列车及应用于轨道列车风挡区域的喷流控制方法,涉及轨道车辆技术领域。轨道列车包括车体,所述车体的端面上设置有外风挡,所述轨道列车还包括喷流装置;所述喷流装置包括吹气单元,所述吹气单元设置于所述车体的端面上且位于所述外风挡的外围,所述吹气单元的吹气方向平行于所述车体的长度方向且朝向对侧的所述车体的端面。本发明提供的轨道列车及应用于轨道列车风挡区域的喷流控制方法,在轨道列车的行进过程中,使吹气单元吹出的气流在相邻的两个车体之间形成与车体外周面平滑过渡的气流层,诱导车体外周的气流沿气流层流动,提高了轨道列车的风挡区域的空气动力学性能。
