摘　　要：将变形技术应用到导弹武器领域,利用变形机构实现水平翼面的快速重构,从而改变导弹的气动外形,实现全飞行剖面的外形优化。首先,提出从固定翼内部伸出弹翼的形式开展变形模式研究,经过优选确定采用两段式伸缩外形的变形模式。然后,对伸缩翼伸出时的飞行马赫数及迎角开展优化设计,针对弹体头部配平后的升阻比特性进行分析,机动飞行段使用最佳升阻比所对应的马赫数及迎角。最后,建立弹道仿真模型进行循环仿真验证,结果表明,该方案可实现导弹全飞行剖面变形策略最优。Proposed to apply the deformation technology to the field of missile weapons, using the deformation mechanism to realize the deformation mechanism to realize the rapid reconstruction of the horizontal wing, so as to change the aerodynamic shape of the missile and realize the shape optimization of the whole flight profile. Firstly, the study of the deformation mode from the internal expansion of the wings of the fixed wing is proposed, and the two-section expansion shape is preferably determined. Then, the design method of optimizing the Mach number and angle of attack, based on the analysis of lift-drag ratio, the flight Mach number and angle of attack corresponding to the optimal lift-drag ratio.Finally, ballistic simulation was established for cyclic simulation verification. The results show that this scheme can optimize the whole flight profile deformation strategy.
