摘要/Abstract

摘要： 导弹弹翼变后掠角是一种重要的变体导弹设计方案,在变体过程中,使用不同的变后掠方式会造成导弹空气动力特性和颤振特性的显著差异。参考“战斧”导弹外形特点,建立变后掠翼导弹几何模型,通过流固耦合方法,对变后掠翼导弹在不同变后掠角方式下的颤振特性进行了计算分析,探究基于颤振特性的变后掠翼方式选取方案。结果表明：在低速状态下,“旋转变后掠”和“剪切变后掠”两种构型的颤振变形均随偶合时间增加呈现收敛趋势;亚声速和跨声速状态下,后者存在发生颤振的可能,跨声速时较为明显,此时前者性能更优。

Abstract: The variable sweep angle of missile wing is an important variant missile design scheme. In the process of variant design, the aerodynamic and flutter characteristics of missile will be significantly different by using different variable sweep methods. Referring to the shape characteristics of Tomahawk missile, the geometric model of variable sweep wing missile is established. The flutter characteristics of variable sweep wing missile under different variable sweep angle modes are calculated and analyzed by fluid structure coupling method, and the selection scheme of variable sweep wing mode based on flutter characteristics is explored. The results show that the flutter deformation of "rotation variable sweep" and "shear variable sweep" configurations converges with the increase of coupling time at low speed; in subsonic and transonic conditions, because the "shear variable sweep" configuration has the possibility of flutter, which is more obvious at transonic speed, so the characteristic "rotation variable sweep" configuration is better.

Key words: variable swept wing, fluid structure coupling, flutter characteristics, simulation calculation
