Abstract: An apparatus for preventing an axial-flow compressor from stalling by employing a casing treatment includes an outer casing having an inner wall with a slot formed to face a rotor blade, an inner casing moveable so as to open the slot in an unstable operating region and close the slot of the outer casing in a stable operating region, and a drive means for moving the inner casing along the axial direction of the outer casing. Thus, the apparatus can be applied not only to a casing treatment structure where the slope of a slot does not vary with the rotational position of the rotor, but also to a casing with a variously shaped slot such as a radial slot or an axial skewed slot.

Abstract: Provided is a sphere magnetic levitation system having magnetic-aligning devices that magnetically align the position of a sphere levitated by electromagnets according to whether the sphere is levitated, and a method of operating the sphere magnetic levitation system. The sphere magnetic levitation system includes: a sphere; a plurality of electromagnets symmetrically positioned about the sphere and spaced apart from the sphere at equal distances; and a plurality of magnetic-aligning devices provided around the sphere, and coming into contact with the sphere or separated from the sphere by a predetermined distance according to the modes of the system. The system is operated in one mode from among: an idle mode, in which the magnetic-aligning devices are in direct contact with and support the sphere; and an operation mode, in which the magnetic-aligning devices are separated from the sphere and the sphere is levitated and rotated.
