Hypersonic viscous interaction effects on measurement of freestreampressure in test section are studied through theoretical analysis, experiment measurement and numerical simulation.
通过理论分析、实验测量和数值模拟，研究高超声速粘性相互作用对实验段自由流静压测量的影响。

It is shown that aerospike nozzle performance losses caused by freestream primarily result from increase of lift body base drag and decrease of plug pressure distribution.
结果表明，外流造成的性能损失主要体现在运载器底部阻力增加和塞锥表面压强降低两方面。
