滑翔增程弹滑翔弹道优化设计分析

Optimizing design of glide trajectory for glide extended-range projectile

针对鸭式布局的滑翔增程弹,建立了滑翔增程弹滑翔弹道的模型,采用使滑翔弹道上每一点的升阻比最大的设计思想进行弹道优化设计,导出了俯仰舵偏角与平衡攻角的表达式,并对滑翔飞行弹道特性进行了仿真计算分析。仿真计算表明,滑翔弹道与常规弹道降弧段相比下降趋缓,增程效果显著。

Based on the analysis of the glide extended-range projectile with canard configuration in flight, the glide trajectory model of the glide extended-range projectile was established, and the glide trajectory was optimized by keeping the biggest lift-drag ratio in glide flight. The formula of lift ca- nard rotating angles and balanceable attack angles were obtained. The simulated computing analyse was made of glide ballistic characteristics. The simulation results show that the glide trajectory fails slower than the falling trajectory of ordinary ballistic with the effect of extending range prominent.
