在这项研究中，一个倾斜的后体的圆柱体磁悬浮无支撑结构的磁悬浮和平衡系统（MSBS）与六自由度（6-DOF）的控制。首次证实了6自由度悬浮过程中的悬浮稳定性，并在15 m/s的自由速度下精确到小于8.9 m和18.6 mdeg。结果表明，采用六自由度控制，模型可以实现刚性悬浮。在此基础上，对悬浮模型进行了气动力测量和尾流可视化。空气动力学和尾流结构的滞后现象在临界雷诺数之间被观察到。
In this study, a cylinder with a slanted afterbody was magnetically levitated without support structures by means of a magnetic suspension and balance system (MSBS) with six-degrees-of-freedom (6-DOF) control. The levitation stability during the 6-DOF levitation was first confirmed and accurate to less than 8.9m and 18.6 mdeg at 15 m/s freestream. The results show that the model can be rigidly levitated with the 6-DOF control. Then, aerodynamic force on the levitated model was measured and its wake was visualized. Hystereses in aerodynamics and wake structure were observed around the critical Reynolds number betweenand.Graphical abstract
