基于GIF技术的三维交会延时控制起爆模型

 基于制导引信一体化技术原理,研究弹目三维交会情形下的战斗部延时控制起爆模型。通过对制导引信一体化技术特点的分析,利用数学方法详细推导了在导引头提供不同弹目交会信息下的剩余飞行时间和延时起爆时间估算算法。研究表明,在战斗部的破片初速及衰减系数一定的情形下,延时起爆时间可以通过弹目距离R、极角θ、方位角ø、极角速度θ、方位角速度ø方便给出。

Initiation Delay Time Control Model Based on GIF

Based on the principle of the guidance integrated fuzing technology(GIF), an initiation delay time control model for missile and target encounter in three-dimensional space is studied. According to the GIF technology, an estimation algorithm is established for the residual flying time and the initiation delay time based on different data of missile and target encounter. It is shown that the initiation delay time can be expressed as a function of the distance between missile and target R, the angles θ, ø, the anglar accelerations θ, ø when the initiation velocity and the attenuation coefficient of warhead fragments are given.
