| Abstract | 高焓激波风洞是开展高超声速电离绕流研究的重要地面模拟设备。在中科院力学所JF-10高焓风洞上通过新的破膜技术获得了稳定运行的试验状态，利用施加高频扫描电压的静电探针来探索模型边界层内的电子密度测量方法研究。为解决高频扫描时线路由于RC特性所带来的噪音干扰问题，针对测试环境发展了新的探针电路。结果表明：新型探针电路大大降低了线路干扰噪音，能够有效测量模型边界层内的电子密度分布规律。 |
| Other Abstract | A laboratory measurements program has been performed in the JF-10 high enthalpy shock tunnel, which provides the aerodynamic and aerothermal conditions wherein plasma environment issues can be quantitatively examined. Electron number density is measured by using a swept-voltage electrostatic probe placed on a 10 degree wedge model. Dual-cable method is explored in order to reduce the induced noise due to the RC characteristic of coaxial cables when a high frequency swept voltage is applied to the probe. Results show that electron density in the boundary layer of the model can be effectively acquired and the dual-cable method turns out to be an effective way for electron density measurement in the short duration test facilities. |
