摘要
有效载荷整流罩的分离设计是中国新一代大型运载火箭长征五号研制过程中的关键技术。对整流罩地面分离试验中负压特性对分离过程的影响进行了研究,建立了对于主要影响因素进行分析的简化模型,并基于AMESim平台开展了趋势研究。同时,结合中国新一代大型运载火箭长征五号整流罩试验结果,采用基于Flow3D平台的CFD方法对分离过程中负压特性进行了仿真,结果与试验趋于一致。
Separation scheme of payload fairing is one of the most key technologies for China new generation launch vehicle Long March 5.Focused on negative pressure characteristics of fairing separation experiment,a simple model is developed for analyzing main factors.Then,negative pressure trends during fairing separation is conducted based on AMESim system simulation platform.Finally,with Flow3D CFD software,detail process of negative pressure formation was researched.Comparison between simulation and experiment indicated that the newly developing model is feasible.
