【摘要】 主要介绍了在氢氧爆轰驱动高焓激波风洞中进行真实气体效应中催化效应对气动热影响的实验研究。首先从测试工作的角度,论述了测热模型、测热传感器及风洞改进等关键技术问题及其解决方法。其次描述了在氢氧爆轰驱动高焓激波风洞中,首次开展气动热风洞试验的过程及其初步结果。结果表明:热流数据随测点位置和迎角的改变呈有规律的变化;在同样条件下,完全催化表面比完全非催化表面热流数值有明显增加的趋向。更多还原

【Abstract】 This paper is mainly concerned with the experiment exploration of catalyst effects on aerodynamic heat in real gas effects in JF-10 oxygen hydrogen detonation driving shock tunnel. Firstly, this dissertation discussed some crucial technical questions and their solved methods such as the design of model and sensors and the improvement of the wind tunnel. Secondly, this dissertation described the experimental process and results in detonation driven shock tunnel. The results showed that heat flow had a well-regulated change with measuring points and the windward angle’s change. At the same condition, the heat flow in full-catalyst surface has a more quantity than that in non-catalyst surface.更多还原
