战斗机是空战的主力军，在大迎角状态下，战斗机的稳定性和操纵性发生急剧变化，易出现失速、偏离和尾旋等危险状况。以F-16战斗机作为分析对象，基于可达平衡集理论求解三维机动可达平衡区域，利用特征根分析平衡点局部稳定性，可为飞行员在空战机动过程中提供安全可靠的空战决策参考。仿真结果表明，大迎角区域下可达范围急剧减少且不对称，对驾驶员稳定控制操纵造成很大限制，与实际情况一致。

The fighters are the main force in air combat.At high Angle-of-Attack (AOA),the stability and maneuverability of the fighters change drastically,and dangerous conditions such as stall,deviation and spin are prone to occur.In this paper,the F-16 fighter is used as the analysis object to solve the 3D maneuverable attainable equilibrium area based on the theory of attainable equilibrium sets,and analyze the local stability of the balance point by using the eigenvalue,which can provide a safe and reliable decision reference for the pilot in the maneuver process of the air combat.The simulation results show that the attainable range in the high angle-of-attack area is drastically reduced and asymmetrical,which is very limited for the driver′s stable control and operation,and it is consistent with the actual situation.
