The invention relates to the technical field of aircraft airspeed calibration, and discloses an aircraft dragging measuring device which comprises a projectile body, an empennage, a dragging part, a total pressure air guide pipe and a static pressure air guide pipe, the empennage is installed at the tail of the projectile body, and the dragging part is installed at the gravity center of the projectile body; a total pressure measuring hole is formed in the top of the projectile body, and a plurality of static pressure measuring holes which are uniformly arranged in the circumferential direction are formed in a projectile body of the projectile body; one end of the total pressure air guide pipe in the bomb body is connected with the total pressure measuring hole, and the other end of the total pressure air guide pipe extends outwards through a dragging part; one end of the static-pressure air guide pipe in the bomb body is connected with the static-pressure measuring holes, and the other end of the static-pressure air guide pipe extends outwards through a dragging part. By using the structure of the projectile body and the empennage, the measurement of atmospheric static pressure and dynamic pressure can be realized, the empennage structure effectively reduces the swing in the flight process, and the stability in the measurement process is improved.

    本发明涉及飞机空速校准技术领域,公开了一种飞机拖拽测量装置,包括:弹体、尾翼、拖拽部、总压引气导管和静压引气导管,所述尾翼安装在弹体的尾部,所述拖拽部安装在弹体重心处;所述弹体的顶部设有总压测量孔,所述弹体的弹身设有若干沿周向均匀排列的静压测量孔;所述总压引气导管在弹体内一端与总压测量孔连接,另一端通过拖拽部向外延伸;所述静压引气导管在弹体内一端与若干静压测量孔连接,另一端通过拖拽部向外延伸。通过使用弹体加尾翼的结构,能够实现对大气静压和动压的测量,尾翼结构有效减少了飞行过程的摆动,提高了测量过程中的稳定性。
