Abstract
A gyro which has a fluidic bearing with two radially spaced circles of orces and two circumferentially and radially spaced exhausts and jet means for producing low pressures in the circumferential exhausts. By using a jet nozzle exhaust control with radial exhaust outlets between two circles of orifices, fluid from one circle of orifices is allowed to exhaust before it can interfere with the other circle of orifices. The fluidic bearing also has exhaust channels between each of the orifices to reduce turbulence and torques present in this area.
Claims6
A gyro comprising a stator housing, a rotor rotatably mounted in said stator housing by fluidic bearing means, said fluidic bearing means having a plurality of inwardly circumferentially arranged ports that have means for admitting fluid to said plurality of inwardly circumferentially arranged ports and said plurality of inwardly circumferentially arranged ports opening into a fluidic space defined between said rotor and said stator housing, a plurality of outwardly circumferentially arranged ports with means for directing fluid to said plurality of circumferentially arranged ports and said plurality of circumferentially arranged ports opening into the fluidic space defined between said rotor and said stator housing, a first circumferentially arranged exhaust from said fluidic bearing space and being located between said plurality of inwardly circumferentially arranged ports and said plurality of outwardly circumferentially arranged ports, a second circumferentially arranged exhaust located radially outwardly of said plurality of outwardly circumferentially arranged ports, and an exhaust channel between each of said plurality of inwardly circumferentially arranged ports and said plurality of outwardly circumferentially arranged ports and in fluid communication with said first exhaust and said second exhaust.
