摘要
结合应用于国防工程中的某型吸声材料的研究,设计了缩比模型发动机和试验装置模型,通过仿真计算对试验方案进行了分析和确认。通过缩比热流试验,研究了火箭发动机的流场分布,验证了吸声材料的抗烧蚀、抗射流冲击能力,对其工程应用价值进行了评估。
During the research of sound-absorption material for underground launch well, a small proportion trial model, which included model engine and accessorial apparatus, designed and validated by numerical simulation. Based on the trial model and project, 3 times launch test carried out. The flow of missile＇s engine studied, the anti-burnout capability and engineering appliance possibility of sound absorption material were validated and evaluated.
