鸭式布局导弹的滚转特性是抑制其性能提升的重要约束。采用数值模拟方法对鸭式导弹滚转特性进行研究,分析舵面后缘后掠角对其影响。以三维可压缩雷诺平均N-S方程为主控方程来模拟流场特性,湍流模型采用SST的k-ω二方程,基于气动特性和流场特性分析研究了固定尾翼鸭式气动布局导弹的横滚特性。仿真结果表明,鸭式布局导弹的舵面后缘后掠角对滚转特性有重要的影响。
The roll-to-roll nature of a duck-type layout missile is an important constraint that inhibits its performance. The numerical simulation method is used to study the rolling characteristics of the duck missile, and the influence of the sweep angle of the trailing edge of the rudder surface is analyzed. The three-dimensional compressible Reynolds averaged Navier-Stokes equations are used to simulate the flow field characteristics. The turbulence model is based on the k-ω two equations of SST. Based on the aerodynamic characteristics and flow field characteristics, the roll characteristics of the fixed-wing ducks aerodynamic layout missile . Simulation results show that the rake angle of the rear edge of the canard layout missile has an important influence on the roll characteristics.
