Various embodiments of the invention include a system having: at least one computing device connected with an array of ultrasonic probes on a gas turbomachine component, the at least one computing device configured to: instruct a first probe in the array of ultrasonic probes to transmit an ultrasonic beam to at least one additional probe in the array of ultrasonic probes; and determine a property of a medium between the first probe and the at least one additional probe based upon a time between transmission of the ultrasonic beam from the first probe and reception of the ultrasonic beam at the at least one additional probe.

Phased array turbomachine monitoring system

Described herein are embodiments of methods and systems of monitoring electrical brushes in electrical rotating machinery. One embodiment of the method comprises continuously measuring at least one parameter associated with an electrical brush; and determining, using the at least one continuously measured parameter associated with the electrical brush, maintenance for the electrical brush.

Method and system of monitoring electrical brushes

The invention relates to a nondestructive ultrasonic test method in which at least one ultrasonic pulse is emitted into a workpiece under test by at least one ultrasonic transmitter (), the ultrasonic pulse is reflected on boundary surfaces within the workpiece, the reflected ultrasound is received by at least one ultrasonic receiver (), and the associated signals are evaluated, the ultrasound penetrating a damping block () that is arranged between the workpiece and the transmitter or receiver. The method is characterized in that it includes at least one step for determining at least one dimension (alpha, d, d) of the damping block () that is relevant for the ultrasonic test; in said step, the propagation time of at least one ultrasonic pulse which is generated by the ultrasonic transmitter (), is reflected on a boundary surface () of the damping block (), and is received by the ultrasonic receiver () is measured, and at least one dimension (alpha, d, d) of the damping block () that is relevant for the ultrasonic test is determined from the measurement.

In one aspect, a system for detecting loads transmitted through a blade root of a rotor blade of a wind turbine is disclosed. The system may include a root attachment assembly configured to couple the blade root to a hub of the wind turbine. The root attachment assembly may include a barrel nut mounted within a portion of the blade root and a root bolt extending from the barrel nut. In addition, the system may include a sensor associated with the root attachment assembly. The sensor may be configured to detect loads transmitted through at least one of the barrel nut and the root bolt.
