联动副翼鸭式导弹滚转控制特性数值研究

为解决鸭式导弹舵翼下洗造成的滚转反效控制问题,提出了一种新的鸭式气动布局方案:在尾翼部位加装联动副翼控制滚转。采用Tecplot和Fluent软件对联动副翼鸭式导弹进行了全弹流场和滚转特性的数值模拟,并运用用经典控制理论分析了滚转控制回路。数值计算结果验证了鸭式导弹采用联动副翼气动方案的可行性,为鸭式导弹的滚转特性研究提供了理论参考。

Numerical Research of Rolling Control Characteristics on Canard-controlled Missile with Linkage Ailerons

To solve the problem of rolling control reversal caused by downwash of the canard missile ′s rudders ,a new canard aerodynamic layout scheme was designed like that linkage ailerons were installed besides tails to control rolling .By taking advantage of Tecplot and Fluent software ,the numerical simula-tion of whole-missile flow fields and rolling characteristics were performed ,and the classic control theory was applied to analyze rolling control circuit .The numerical calculation results had not only verified the feasibility of aerodynamic layout scheme of the canard missile with linkage ailerons ,but also provided the-oretical guidance for the study of rolling characteristics about canard missiles .
