半捷联导引头光轴稳定的研究

Light axis stabilization of half-strapdown seeker

以红外空空导弹为背景,分析了导引头光轴稳定对导弹精确打击目标的重要性,介绍了动力陀螺、速率陀螺和捷联三种稳定导弹导引头光轴的典型稳定方案,并将前两种方案与捷联稳定方案进行比较,同时根据国外空空导弹的发展趋势和捷联稳定原理,运用横滚/摇摆伺服系统结构,提出了一种半捷联稳定方案,并在理想状态下进行了数学仿真验证。结果表明,该方案稳定导引头光轴的性能良好,可行性较强。

The importance of the light axis stabilization for the missile attacking aim accurately is analyzed on the background of air-to-air missile. Power gyroscope stabilized project, rate gyroscope stabilized project and strapdown stabilized project are introduced.By comparing the former two projects with the strapdown stabilized project, a new half-strapdown stabilized project is proposed based on the international developing trends of air-to-air missile and the theory of strapdown stabilization.The new half-strapdown stabilized project is simulated using the horizontal-roll/swing configuration of the servo system in computer under ideal state.The result proves that this new half-strapdown stabilized project has better feasibility and capability for the seeker＇s light axis stabilization.
