为了保证运载火箭飞行轨迹计算软件对各类点位组合的适应性,需要对所有可能的点位组合进行全覆盖性测试,点位组合数量以亿次计,计算量巨大。文章提出了一种基于分布式并行调度的运载火箭飞行轨迹快速计算技术,采用“1+N”的分布式并行计算架构完成分布式并行计算调度平台设计与实现。通过计算验证,提出的基于分布式并行调度的运载火箭飞行轨迹快速计算技术使得点位测试过程中计算机资源使用率接近100%,大幅度提高了计算速度,将原有年量级的计算工作缩减至几天内完成,并且不影响计算结果的准确性。

In order to ensure the adaptability of the launch vehicle flight trajectory calculation software to various point combinations,it is necessary to conduct full coverage tests on all possible point combinations,and the number of point combinations is hundreds of millions of times,and the calculation amount is huge.This paper proposes a rapid flight trajectory calculation technology for launch vehicles based on distributed parallel scheduling,and uses the“I+N”distributed parallel computing architecture to complete the design and implementation of the distributed parallel computing scheduling platform.Through calculation verification,the proposed rapid calculation technology of launch vehicle flight trajectory based on distributed parallel scheduling makes the utilization rate of computer resources close to 100%in the process of point testing,greatly improves the calculation speed,shortens the original annual calculation work to a few days,and does not affect the accuracy of the calculation results.
