面向战略导弹的新一代惯性系统

A New Generation Inertial System for Strategic Missile

自主式惯性制导系统是战略导弹"威慑可信、反击可靠"的保障,针对我国已装备的战略导弹惯性系统在高精度、高可靠、实战化等方面存在的不足,系统阐述了位置捷联、位置平台和速率捷联的工作特点和局限性,首次提出了一种可同时满足高精度、全姿态、小型化的新一代惯性系统——速率平台。该惯性系统既具备速率捷联系统小型化、全姿态的特点,又兼顾了位置平台系统隔离角运动的功能。针对战略级惯性系统冗余不足引起的可靠性问题,在速率平台的基础上从智能化的角度提出了具备导航级故障诊断和自主重构的新体制惯性系统,该惯性系统将首次具备了自主导航、自主控制与自主重构的能力。

Self-type inertial guidance system is the guarantee of strategic missile’s credible deterrence and reliable counterattack.In view of the shortcomings of China’s equipped strategic missile inertial system in terms of high-precision,high-reliability and practical combat,the working characteristics and limitations of position strapdown system,position platform system and rate strapdown system are systematically expounded in this paper.A new generation inertial system—rate platform is proposed for the first time,which could meet the requirements of high-precision,full-attitude and miniaturization.This inertial system not only has the characteristics of miniaturization and full-attitude of rate strapdown system,but also takes into account the function of isolating angular motion of position platform system.Aiming at the reliability problem caused by insufficient redundancy of strategic level inertial system,a new inertial system with navigation-level fault diagnosis and self-reconfiguration is proposed from the intellectualization of view on the basis of rate platform.This inertial system will have the abilities of self-navigation,self-control and self-reconfiguration for the first time.
