Side Jet and Aerodynamics Compound Control System Design of Air Defense Missiles

以大气层内拦截导弹侧向直接力和气动力的复合控制系统为研究对象 ,首先分析了侧向喷流与来流的干扰现象 ,建立了通过干扰放大因子来描述的侧喷与来流的干扰模型和侧向直接力与气动力的复合控制模型 ,将复合控制系统分解为直接力子系统和气动力子系统 ,并分别针对侧向直接力和气动力的特点设计了直接力控制子系统和气动力控制子系统 。

The compound control system of an intercept missile by means of combining the traditional aerodynamics control with reaction jets control is studied in this paper. At first, the phenomenon of side jet interaction with external flow is analyzed, and the interaction model is presented by the jet interaction amplification factor ( K ), and then the compound control model of jet thrust and aerodynamics is established. The compound control system is divided into two subsystems: the divert thrust subsystem and the aerodynamics subsystem. The different control methods are designed for each subsystem, and the performance of the compound control system and each subsystem is simulated and analyzed.
