球头双锥再入体表面脉动压力环境的分析与预测

The analysis and prediction of fluctuating pressure on the sphere-biconic reentry vehicles

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 。

Some engineering correlations have been developed to predict the fluctuating pressure distribution on the sphere biconic shape reentry vehicles surface in supersonic/hypersonic flow field.Utilizing the pressure distribution,we achieved a series of reasonable results comparing with test data.
