The invention provides a weather vane airspeed tube which comprises an airspeed tube body, a weather vane rotating shaft, a weather vane turning mark, a rotating shaft upper shaft sleeve and a rotating shaft lower shaft sleeve, wherein the rotating shaft upper shaft sleeve is arranged at one end of the weather vane rotating shaft, the rotating shaft lower shaft sleeve is arranged at the other end of the weather vane rotating shaft, the rotating shaft upper shaft sleeve is connected to the weather vane turning mark, and the rotating shaft lower shaft sleeve is connected to the airspeed tube body. According to the weather vane airspeed tube provided by the invention, the weather vane rotating shaft, the weather vane turning mark, the rotating shaft upper shaft sleeve and the rotating shaft lower shaft sleeve are arranged, and the weather vane rotating shaft is connected to the weather vane turning mark through the rotating shaft upper shaft sleeve and connected to the airspeed tube body through the rotating shaft lower shaft sleeve so that the weather vane turning mark has two rotational degrees of freedom; and the weather vane turning mark can adapt to a high wind resistance in the air, the deviation probability of the weather vane rotating shaft and the shaft sleeves is reduced, the rotating stability of the weather vane turning mark is ensured through the arrangement of the double shaft sleeves, and then accurate measurement of the airflow direction is ensured.

    本发明提供了一种风标空速管,包括:空速管本体、风标转轴、风标转向标、转轴上轴套和转轴下轴套;其中,所述风标转轴的一端设置有转轴上轴套,另一端设置有转轴下轴套,所述转轴上轴套连接于所述风标转向标,所述转轴下轴套连接于所述空速管本体。本发明提供的风标空速管,通过风标转轴、风标转向标、转轴上轴套和转轴下轴套的设置,风标转轴通过转轴上轴套连接于风标转向标,通过转轴下轴套连接于空速管本体,使得风标转向标具备两个旋转自由度,使得风标转向标能够适应于高空中的高风阻,降低了风标转轴与轴套偏移的概率,通过双轴套的设置,确保了风标转向标旋转的稳定性,进而保障了气流方向测量准确。
