摘　　要：针对先进空空导弹研制中出现的无控火箭弹弹道失稳问题进行了分析,建立了火箭弹弹体纵向、横向及二者交叉耦合的数学模型,开展了共振现象的数字仿真,对火箭弹弹道失稳的机理进行了探讨研究。结果表明,火箭弹弹道失稳的根本原因是先进空空导弹降低静稳定度后弹体纵横向运动耦合发生了共振。在分析先进空空导弹技术特点的基础上,结合数字仿真研究和工程实践,提出了保证无控火箭弹飞行稳定的主动控制措施和被动控制措施,经飞行试验验证了措施有效。同时指出,在有控弹上不存在类似的弹道失稳问题。The trajectory instability of uncontrolled rocket appears during the development of advanced air-to-air missile(AAAM).Aiming at this problem,the longitudinal and lateral mathematical models of the rocket body were established,as well as the mathematical model of cross-coupling.The numerical simulation of resonance phenomenon was carried out,and the mechanism of trajectory instability was studied.It is the fundamental reason that the longitudinal and lateral coupling resonates when the static stability of AAAM reduces.Combined with numerical simulation research and engineering practice,the active control measures and passive control measures were proposed to ensure the flight stability of uncontrolled rocket based on the technical characteristics of AAAM,and the flight test proved the measures effective.It also points out that there is no similar trajectory instability problem with controlled missile.
