STAND FOR TESTING GAS-DYNAMIC BEARINGS Russian patent published in 2015 - IPC G01M13/04 

FIELD: testing equipment.

SUBSTANCE: stand comprises a stator, in which a rotor is located, mounted in two supports made with the ability to contain the gas-dynamic bearings tested. Each of the supports is provided with motion sensors located in mutually perpendicular planes passing through the axis of rotation of the rotor, a temperature sensor, and an air supply unit. The air supply unit is connected to the source of compressed air and comprises a heater for changing the temperature of the supply air and a valve with an electric drive connected to the control unit. The rotor is provided with a disc which weight and size parameters correspond to the parameters of the compressor impeller of the turbomachine. The stand also has a rotation velocity sensor and a vibration sensor.

EFFECT: expanding the functional capabilities of the stand.
