The invention relates to an aircraft test flight multi-scene gravity center adjusting method and system. The method comprises the following steps: receiving target gravity center data required by test flight and a rolling angle and a pitching angle of an aircraft; judging whether the rolling angle is greater than a rolling angle threshold value or not; when the rolling angle is larger than the rolling angle threshold value, the transverse pipe valve between the water tanks is closed, and gravity center adjustment is suspended; when the rolling angle is smaller than or equal to the rolling angle threshold value, a transverse pipe valve between the water tanks is opened, and whether the pitching angle is smaller than a first pitching angle threshold value or not is judged; when the pitching angle is smaller than a first pitching angle threshold value, the gravity center is adjusted in a water tank external circulation mode; when the pitching angle is larger than or equal to a first pitching angle threshold value and smaller than a second pitching angle threshold value, the second pitching angle threshold value is larger than the first pitching angle threshold value, and gravity center adjustment is conducted in a water tank internal circulation mode; when the pitching angle is larger than or equal to the second pitching angle threshold value, the gravity center adjustment is suspended.

    本发明涉及飞机试飞多场景重心调节方法和系统。该方法包括:接收试飞所需目标重心数据、以及飞机的滚转角度和俯仰角度;判断滚转角度是否大于滚转角度阈值;当滚转角度大于滚转角度阈值时,关闭水箱间横管阀,暂停重心调节;当滚转角度小于或等于滚转角度阈值时,开启水箱间横管阀,且判断俯仰角度是否小于第一俯仰角度阈值;当俯仰角度小于第一俯仰角度阈值时,采用水箱外循环方式进行重心调节;当俯仰角度大于或等于第一俯仰角度阈值且小于第二俯仰角度阈值时,其中第二俯仰角度阈值大于第一俯仰角度阈值,采用水箱内循环方式进行重心调节;当俯仰角度大于或等于第二俯仰角度阈值时,暂停重心调节。
