空间平台武器系统传递对准的机动方案设计

针对空间平台武器系统传递对准的机动方案设计进行了讨论。首先建立了考虑弹性形变的传递对准模型和空间导航解算所需的轨道运动学模型;然后提出了综合考虑对准精度、对准速度与能量损耗的相对性能指标;最后,选取"速度 姿态"匹配法从推力方向、推力变化曲线、推力周期个数及推力峰值等四方面分析了不同机动方案对传递对准结果的影响。仿真计算表明,推力按半正弦曲线变化、两轴依次重复助推的机动模式较好,而机动的时间和幅度则应根据性能指标选取适当的值。

Maneuvering scheme of transfer alignment for weapon system on space platform

First, the transfer alignment model considering wing flexure and the obit kinematics model for navigation calculation were established. Then, a relative performance index considering alignment accuracy, rapidity and energy loss was presented. Finally, using "velocity attitude" information matching method, the paper analyzed the impact on transfer alignment results by various maneuvering manners with different thrust direction, curve, periods and peak value. The simulation show that the maneuvering mode that the thrust changes by half-sine-curve and acts repeatedly in order along two axes is preferable, and the maneuvering duration and range should be determined properly based on the performance index.
