Abstract
An air levitation jet located in the center of a rotor seat to provide a supporting and holding air flow between a rotor and the rotor seat. Integrally formed within both the rotor and the rotor seat are conical and frustoconical portions which respectively establish a conical flow path and an adjoining frustoconical flow path to aid not only in the centering of the rotor within the rotor seat, but also in the retaining of the rotor in alignment with its rotational axis. Air under pressure exiting the levitation air jet in the center of the rotor seat proceeds along the conical flow path and into the frustoconical flow path with sufficient velocity to establish a reduced pressure in the flow path between the rotor and rotor seat that is less than atmospheric pressure, causing the rotor to remain securely positioned on a cushion of air within the rotor seat.
