摘要
为了研究制导炮弹陀螺姿态测量的空中初始对准问题,根据弹箭绕心运动特性分析,引入动力平衡角近似攻角,建立基于全球定位系统测量数据的陀螺姿态测量空中对准模型,利用解析求得弹箭滚俯仰角和偏航角初始值。基于某弹箭测量仿真数据进行初始姿态仿真计算,仿真结果表明,采用该方法得到的姿态状态与理论值基本吻合,满足制导炮弹俯仰角和偏航角陀螺空中对准要求。
In order to study the gyros inflight alignment for guided projectiles,according to principles of the motion about the mass center,the inflight alignment model for projectiles attitude is build up by using the gyros and global positioning system(GPS),which replaces the angle of attack with the dynamic equilibrium angle.The initial values for the pitch angle and yaw angle are calculated.The simulation calculation for one guided projectile is performed based on the compound measurement data.The results indicate that attitude angles of simulation are approximately equal to the theoretical values,and this method can satisfy the requirement of the inflight alignment for the pitch angle and yaw angle.
