摘要
研究了弹道修正弹末段脉冲推力控制的应用.通过对弹上脉冲推力控制器布置、激光探测器工作过程和弹丸受力情况的分析,建立了俯仰平面内弹道修正弹末段脉冲推力控制的弹道模型,研究了脉冲推力的射程修正能力及非质心脉冲推力对弹体姿态的影响.仿真结果表明,在非质心脉冲推力作用情况下,由于弹体自身阻尼小,脉冲控制力矩使弹体摆动的角度大、过渡过程时间长,很难采用闭环控制的弹体追踪制导律.
The application of terminal impulse thruster control of trajectory correction projectile was researched. By analyzing the layout of impulse thruster controllers, and the work process of laser detector and forces which acted on the trajectory correction projectiles, a impulse force control trajectory model on pitch plane was established. The range correction ability of impulse force and body attitude while impulse forces not acting on the center of gravity was studied. Simulation results indicate that on the condition of impulse forces not acting on the center of gravity of the projectile, the damp of the body is small, the swaying angle of body is large, and the transient time is long because of the impulse force moment. It is difficult to adopt closed loop controlled body to pursuit guidance law.
