本文根据超声速和高超声速流动特征分析了球头双锥再入体的表面脉动压力环境特性 ,并根据超声速和高超声速流动情况下球头双锥的表面压力分布给出一套预测球头双锥再入体表面脉动压力分布的工程估算公式。计算结果表明 ,预测的均方根脉动压力分布与实验结果基本一致
In this paper, based on the characteristics of supersonic and hypersonic flow, the surface pulsating pressure environment characteristics of the double cone of the ball were analyzed. Based on the surface pressure distribution of the double cone in the supersonic and hypersonic flow conditions, Reconstruction of the pulsation pressure distribution on the surface of the engineering estimation formula. The calculation results show that the predicted root mean square pulsation pressure distribution is in good agreement with the experimental results
