The invention relates to an airspeed system for improving the measurement precision and reliability of an airspeed tube of a light aircraft, which comprises a pitot tube fixed on a wing of the light aircraft, the pitot tube is provided with a total pressure tube adapter and a static pressure tube adapter, the total pressure tube adapter of the pitot tube is fixedly connected with a total pressure tube, and the rear side of a cab of the light aircraft is provided with two branch static pressure tubes. One ends of the two branch static pressure pipes are respectively fixed on the left side wall and the right side wall of the rear section of the light aircraft body, the other ends of the two branch static pressure pipes are respectively fixed on two joints of the first three-way joint in an inserting and sleeving manner, the rest joints of the first three-way joint are fixedly provided with the total static pressure pipe in an inserting and sleeving manner, and the tail end of the total static pressure pipe and the tail end of the total pressure pipe are fixedly connected with the airspeed measuring element. The airspeed system can effectively improve the measurement precision of the existing airspeed tube system on the airspeed; and meanwhile, the reliability of the existing airspeed tube system in rainy days can be improved.

    本发明涉及一种提高轻型飞机空速管测量精度及可靠性的空速系统,包括固定在轻型飞机机翼上的皮托管,皮托管上设有全压管接管和静压管接管,皮托管的全压管接管上固定连接有全压管,轻型飞机驾驶室的后侧设有两根分静压管,两根分静压管的一端分别固定在轻型飞机机身后段的左、右侧壁上、另一端分别插套固定在第一三通接头的两个接头上,第一三通接头剩余的接头上插套固定有总静压管,总静压管的末端和全压管的末端固定连接有空速测量元件上。本空速系统能有效改善现有空速管系统对空速的测量精度;同时能改善现有空速管系统在雨天的可靠性。
