摘要
报道了在爆轰驱动高焓激波风洞中开展带尾翼钝锥体电子密度测试的相关研究工作进展。试验气流为4km/s,密度为0.001kg/m3。诊断尾翼对尾流的影响时,为不影响流场并获得足够的空间分辨率采用针状静电探针;实验结果给出带尾翼模型对尾流电子密度影响的定量结果及受影响的空间区域。
It is reported that the electron density measurement in the flow field of blunt cone body which modeled in detonation-driven high-enthalpy shock tunnel.The test flow velocity is 4km per second and the flow density is 0.001kg per cubic meter.In order to obtain high resolution data,needle probe is used for the diagnosis of the wake flow of the tailed model.Results are given for the description of the wake electron density when there is a tail on the blunt cone body.
