摘要

利用背景定向纹影（BOS）技术在日本东北大学流体科学研究所的弹道范围内对隼鸟号返回舱模型进行了三维密度测量。弹丸采用直径为15mm的隼鸟号返回舱模型，马赫数为1.20。提出了一种基于BOS图像的胶囊模型位置和姿态检测方法，并进行了围绕自由飞行试验模型的非定常流场测量。从结果中，我们成功地测量了胶囊模型周围的三维密度分布，并可视化了尾流区域的详细结构。

Three-dimensional density measurement around a Hayabusa re-entry capsule model in the ballistic range

Three-dimensional density measurement around a Hayabusa re-entry capsule model using the background-oriented schlieren (BOS) technique is carried out in the ballistic range at the Institute of Fluid Science, Tohoku University. A Hayabusa re-entry capsule model with a diameter of 15 mm is used for a projectile, and the Mach number was 1.20. A method of model Position and Pose detection from BOS images was proposed for a capsule model, and unsteady flow field measurement around a free-flight test model was conducted. From the results, we succeeded in measuring the three-dimensional density distribution around a capsule model and visualizing the detailed structure in the wake region.

期刊介绍： Experiments in Fluids examines the advancement, extension, and improvement of new techniques of flow measurement. The journal also publishes contributions that employ existing experimental techniques to gain an understanding of the underlying flow physics in the areas of turbulence, aerodynamics, hydrodynamics, convective heat transfer, combustion, turbomachinery, multi-phase flows, and chemical, biological and geological flows. In addition, readers will find papers that report on investigations combining experimental and analytical/numerical approaches.
