摘要

本文将讨论在太空发射系统（SLS）计划中使用计算流体动力学（CFD）来模拟飞行的上升阶段。上升阶段从运载火箭离开发射塔后不久开始，一直持续到第一次中转。为了模拟 SLS 的上升过程，我们求解了 1000 多个 Navier-Stokes 方程的数值解，并对五种不同的 SLS 配置重复进行了分析。为了完成这项高难度的上升 CFD 任务，SLS 计划开发了计算航空科学生产力与执行软件。本文还讨论了过去十年中 CFD 和高端计算的一些发展方式，并与航天飞机计划中使用的 CFD 进行了一些比较。

Launch Vehicle Ascent Computational Fluid Dynamics for the Space Launch System

This paper will discuss the use of computational fluid dynamics (CFD) for the Space Launch System (SLS) program to model the ascent phase of flight. The ascent phase begins shortly after the vehicle clears the launch tower and extends to the first staging event. To model SLS’s ascent, over 1000 numerical solutions of the Navier–Stokes equations were solved, and this analysis has been repeated for five different SLS configurations. To manage this demanding ascent CFD task, the SLS program has developed the Computational Aerosciences Productivity & Execution software. The paper also discusses some of the ways that CFD and high-end computing have advanced in the last decade and offers some comparisons to CFD used in the Space Shuttle Program.
