The invention provides an airspeed tube and an aircraft. The airspeed tube comprises: a housing; the first dynamic pressure air inlet and the second dynamic pressure air inlet are formed in one side surface of the shell, and the position of the first dynamic pressure air inlet is higher than that of the second dynamic pressure air inlet; the dynamic pressure gas communicating pipe is communicated with the first dynamic pressure gas inlet and the second dynamic pressure gas inlet; one end of the dynamic pressure gas conveying pipe is communicated with the dynamic pressure gas communicating pipe, and the other end of the dynamic pressure gas conveying pipe extends upwards to the upper part of the shell. According to the airspeed tube, accumulated water in the airspeed tube caused by rainwater or condensate water entering the atmosphere can be eliminated, and the situation that the accumulated water forms a water film in a pipeline of the airspeed tube, and consequently the measurement precision of the air pressure of the environment where the aircraft is located is affected is prevented.
本发明提供一种空速管及飞行器,该空速管包括:壳体;第一动压进气口和第二动压进气口,设在所述壳体的一个侧表面,所述第一动压进气口的位置高于所述第二动压进气口的位置;动压气体连通管,所述动压气体连通管连通所述第一动压进气口和所述第二动压进气口;以及动压气体输送管,所述压气体输送管的一端连通到所述动压气体连通管,所述动压气体输送管的另一端向上方延伸到所述壳体的上部。根据本发明,能够消除由大气中进入的雨水或者冷凝水等造成的空速管内部的积水,防止这些积水在空速管的管路中形成水膜而影响飞行器所处环境气压的测量精度。
