| 摘要: |
| 运载火箭弹道设计对初值的选取敏感，需要设计人员具备相应经验，新构型或新任务下迭代设计易发散，设计过程依靠人员手动调整，效率较低。应用权衡空间探索及全局优化思想，给出了多约束弹道设计初值确定方法，并在此基础上重新建立了弹道设计流程，自动完成初值选取及精确设计，降低了设计过程对人员经验的依赖性，提升了弹道设计方法的智能化程度，提高了论证及设计效率。 |

| Abstract: |
| Trajectory design of launch vehicle is sensitive to the selection of initial values, requiring designers to have corresponding experience. Iterative design under new configurations or tasks is easy to diverge. The design process relies on designer to adjust manually and is less efficient. By applying trade-space exploration and global optimization ideas, a method for determining the initial values of multi-constrained trajectory design is proposed, and on this basis, the engineering trajectory design process is rebuilt. The initial values selection and accurate design are automatically completed, reducing the dependence of the design process on designer experience, and improving the intelligent level and efficiency of demonstration and design. |
