Study of the surface wind load and response of carrier rocket
-
摘要: 通过捆绑式运载火箭在地面风环境下的风洞试验,分析了不同试验条件下主体火箭及助推器各测压截面压力分布的变化规律。结果表明:主体火箭和助推器之间的相互干扰、发射塔架对于火箭的影响都很明显。另外,对其气动弹性模型在地面风荷载下的动态响应亦进行工程计算,并与试验结果有良好的一致性。Abstract: This paper describes some wind tunnel experiments of boosted carrier rockets in ground wind surrounding.The changing laws of pressure distributions on the different pressure measuring cross sections of main rocket and boosters are analyzed.The interaction between the main rocket and boosters,and the influence of the launching tower on the rocket are evident.The along-wind and across-wind dynamic responses of aeroelastic model under ground wind load are calculated.The results are in good agreement with the measured responses.
