The invention discloses a safe lifesaving method under a complex posture. The safe lifesaving method comprises the following steps: step 1, determining a coordinate system of a person-chair system; 2, adopting a single pitch attitude control strategy according to the speed and attitude information when the person-chair system is ejected out of the cabin under the conditions that V is smaller than or equal to V0, the pitch angle theta is larger than or equal to 60 degrees, and gamma is larger than or equal to-180 degrees and smaller than or equal to 180 degrees; 3, judging the speed V < = Vpreset and the speed H < = Hpreset, and if yes, completing separation parachute shooting; otherwise, continuing the step 3. By means of the method, the seat can achieve safe lifesaving under the large pitching working condition, and the safe lifesaving performance of the ejection seat under the conditions of low altitude, low speed and unfavorable postures is improved.

    本发明公开了一种复杂姿态下的安全救生方法,包括如下步骤:步骤一:明确人‑椅系统的坐标系;步骤二:依据人‑椅系统弹射出舱时的速度和姿态信息,在满足V≤V0且俯仰角|θ|≥60°、‑180°≤γ≤180°下,采取单俯仰姿态控制策略;步骤三:判断速度V≤V预设和H≤H预设,若满足完成分离射伞;否则,继续步骤三。该方法使座椅能够实现大俯仰工况下的安全救生,提高弹射座椅在低空、低速、不利姿态情况下的安全救生性能。
