The invention belongs to the technical field of flight control, and discloses a tail spin changing method which comprises the following steps: S1, judging the tail spin of an aircraft according to the attack angle, the yaw angle rate, the roll angle and the vertical rate of the aircraft, judging whether the aircraft enters the tail spin or not, and judging the type of the aircraft entering the tail spin; s2, according to the steering effect of the aileron, the rudder and the elevator at the large angle of attack, different tail rotation reformation strategies are adopted, and a control surface instruction is given; according to the current flight state of the aircraft, superposing a control surface instruction output by human manipulation and a control surface instruction output by tail rotation; when the absolute value of the attack angle is larger than 10 degrees, the attack angle is large; and S3, judging whether the tail spin of the aircraft is changed, if the aircraft is still in the tail spin, repeating the step S2, and otherwise, exiting to improve the survival probability of the aircraft under the possible tail spin condition.

    本发明属于飞行控制技术领域,公开了一种尾旋改出方法,包括:S1,根据飞机迎角、偏航角速率、滚转角、垂直速率进行飞机的尾旋判定,判断飞机是否进入尾旋,并判定飞机进入尾旋的种类;S2,根据副翼、方向舵和升降舵在大迎角下的舵效,采用不同的尾旋改出策略,并给予舵面指令;根据飞机当前的飞行状态,对人操纵输出的舵面指令和尾旋输出的舵面指令进行叠加;迎角绝对值大于10度称为大迎角;S3,判断飞机是否已经改出尾旋,如果仍在尾旋中,重复S2,否则退出,以提升飞机在可能面临的尾旋情况下的生存概率。
