针对高超声速助推滑翔飞行器远程拦截问题,结合球面三角形,提出在临近空间远程拦截目标飞行器时拦截发射诸元的求解思路。选取经典飞行器控制程序角模型,以时间与射程为控制目标合理设计了拦截器助推段弹道,并提出用平衡滑翔假设解析方程快速预报射程从而求解飞行器的拦截发射方位角的方法。仿真结果表明,所提出的拦截发射诸元设计方法可以成功将拦截器送到目标飞行器周围。
Based on remote interception of hypersonic boost-gliding vehicle,considering the spherical triangle,the idea about computing the elements of the interception is described. The classical model of the controlling angle is choosesed and the boost trajectory is designed by the control objective of time and range. According to the equilibrium gliding hypothesis,the dissertation has deduced the relationship between the state and time,then the relationship is used to solve azimuth of the interceptor. The result shows that the design of the launching elements is effective.
