The invention discloses a hollowed-out empennage assembly, an automobile and a method for improving wind noise of a hollowed-out empennage, and belongs to the technical field of automobile manufacturing, the hollowed-out empennage assembly comprises a hollowed-out empennage and a wind turbine, the hollowed-out empennage is used for being installed on an automobile body, and a hollowed-out channel is formed between the hollowed-out empennage and the automobile body; the wind turbine is located in the hollowed-out channel and comprises a base and rotating blades installed on the base, the base is used for being installed on the portion, at the hollowed-out channel, of the vehicle body, and the rotating blades rotate under the action of airflow passing through the hollowed-out channel. The wind turbine is arranged in the hollowed-out channel of the hollowed-out empennage, the rotating blades of the wind turbine are used for capturing wind energy and reducing the flow speed of airflow, and therefore the flow field of the hollowed-out channel is changed, and aerodynamic noise generated by the hollowed-out empennage can be effectively reduced on the premise that it is guaranteed that the performance and the appearance attractiveness of an automobile are not affected.

    本发明公开一种镂空尾翼组件、汽车及改善镂空尾翼风噪的方法,属于汽车制造技术领域,镂空尾翼组件包括镂空尾翼以及风力机,所述镂空尾翼用于安装在车身上,所述镂空尾翼与车身之间具有镂空通道;所述风力机位于所述镂空通道中,所述风力机包括底座和安装于所述底座的旋转叶片,所述底座用于安装在所述镂空通道处的车身上,所述旋转叶片在经过所述镂空通道的气流的作用下进行转动。本发明通过在镂空尾翼的镂空通道内设置风力机,利用风力机的旋转叶片捕捉风能,降低气流的流速,从而改变镂空通道的流场,进而能够在确保汽车性能和外观美观性不受影响的前提下,有效降低镂空尾翼产生的气动噪声。
