摘要
应用统计能量分析方法对某型运载火箭整流罩的噪声环境进行了预示,与试验数据对比得到了较好的吻合,通过降噪结构设计可以明显降低整流罩内噪声,可供设计参考。
Based on statistical energy analysis, the noise environment of the payload fairing is predicted, and satisfying result is obtained which consists well with experiment data. The noise level of fairing can be decreased through anti-acoustic design, and the conclusion can provide theoretic base for noise control.
