Abstract

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 8.9 μm 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 between 3.3 × 10 ⁴ and 3.6 × 10 ⁴. Graphical abstract: [Figure not available: see fulltext.]
