GEOMETRIC PROGRAMMING DESIGN OF SPACECRAFT PROTECTIVE STRUCTURES TO DEFEAT EARTH-ORBITAL SPACE DEBRIS

文章描述了一个用于航天器防护结构综合优化的独特方法——几何规划优化技术,以减小暴露于流星体和空间碎片超高速碰撞环境下的航天器防护结构系统的重量。空间碎片和流星体环境由广义加权目标函数的公式来定义。通过Wilkinson,Burch和Nysmith超高速碰撞预示模型说明几何规划的性能。表明遵循几何规划形式的超高速碰撞模型,可以进行综合非线性设计优化。

A unique methodology providing global optimization of spacecraft protective structures is presented to minimize spacecraft weight of protective structural systems exposed to meteoroid and space debris hypervelocity impacts.The space debris and meteoroid environment are defined followed by the formulation of the general weight objective function.The Wilkinson,Butch,and Nysmith hypervelocity impact predictor models are then used to display Geometric Programming capabilities.Results show that global nonlinear design optimization can be performed for hypervelocity impact models that follow the Geometric Programming form.
