FIELD: engineering of power and transportation machines and mechanisms. ^ SUBSTANCE: device for controlling and diagnosing condition of frictionless bearings and other elements of gas-turbine engine includes oscillation transformation device, information processing device connected to aforementioned measuring transformer by connecting devices. As primary sensor, device uses oil discharge pipe of controlled bearing, which pipe is connected to oil cavity of the bearing and which projects to the outside of hot engine body. Also, as a transformer of oscillations signal of the surface of the pipe for discharging oil from the bearing, sensors with piezo-transformers are used, positioned on the surface of the pipe. ^ EFFECT: increased efficiency. ^ 3 dwg |
