Disclosed herein is a non-destructive inspection system. The non-destructive inspection system comprises a motion platform and a tool assembly. The tool assembly is coupled to the motion platform such that the tool assembly is movable relative to the motion platform. The tool assembly comprises an inspection tool assembly that comprises a base structure coupled to the tool assembly and a plurality of probe assemblies coupled to the base structure. Each probe assembly comprises a first linear actuator and a probe, different from the probe of any other one of the plurality of probe assemblies, for inspecting a different structural feature of a structure. Each probe is moveable, along a first axis relative to another one of the probes and substantially perpendicular to the base structure, using the first linear actuator of the corresponding one of the plurality of probe assemblies.

A motorized rolling maintenance cart that utilizes the angled trailing edge geometry of an airfoil-shaped body (such as a wind turbine blade or rotor blade) to traverse the length of the airfoil-shaped body. The trailing edge-following maintenance cart may be used to carry personnel doing maintenance activities on the blades, such as local repairs or re-painting. In accordance with one aspect, the maintenance cart carries non-destructive inspection sensor units or other maintenance hardware over the surface of the airfoil-shaped body (e.g., in a spanwise direction). In accordance with another aspect, the trailing edge-following maintenance cart is configured to also provide fall protection to one or more independently movable crawler vehicles by means of cables. Alternative embodiments may include only one of the two aspects.

Embodiments of the present disclosure provide systems, methods, and computer-readable storage media configured to monitor wind turbines and detect damage to one or more components of the wind turbines, such as damage to the blades. The techniques disclosed herein may utilize sensors (e.g., acoustic sensors) disposed within air cavities of one or more blades of the wind turbines to detect acoustic signals or acoustic energy caused by corrosive impacts (e.g., wind, dust, rain, hail, lightning, etc.) to the wind turbine. Information associated with the acoustic signals may be provided to and received by a processor used to determine whether one or more of the blades of the wind turbines have been damaged. The techniques disclosed herein may facilitate real-time or near-real-time monitoring of wind turbines for damage, which may enable more efficient operation and maintenance of wind turbines.

A method for the nondestructive crack testing of surfaces of rotor blade-receiving blade reception slots of a rotor, includes the following steps: positioning a guide rail on a rotor surface section between two rotor blades; positioning an ultrasound test head oriented in the direction of at least one blade reception slot and is moveable in a manner guided along a trajectory predefined by the shape of the guide rail; moving the test head along the trajectory in the installed state of two adjacently arranged rotor blades and checking the surface of the blade reception slot for the presence of cracks using the ultrasound test head, wherein cracks that are present are detected in the form of data using the ultrasound test head; diagnosing the rotor state on the basis of the data.

Described herein is a method of monitoring a condition of a component of a gas turbine engine, comprising: obtaining, with a non-contact monitoring sensor, monitoring data, wherein a portion of the monitoring data relates to the condition of the component of the gas turbine engine; obtaining, using a position sensor, positional data relating to the component's position; communicating the monitoring data and the positional data to a processing module, and analysing, using the processing module, the monitoring data and positional data to determine the portion of the monitoring data which relates to the component and determine a condition of the component. Also described herein is a system for monitoring and a gas turbine engine comprising the system.

An inspection method according to the present disclosure includes a step of mounting an ultrasonic probe, a step of mounting a pulser receiver, a step of causing the ultrasonic probe to transmit ultrasonic waves, a step of causing the ultrasonic probe to receive a reflected wave of the ultrasonic waves reflected by the wind turbine blade, a step of causing the pulser receiver to acquire reflected-wave data, a step of causing the pulser receiver to wirelessly transmit the reflected-wave data, a step of causing at least one of antennas to receive the wirelessly transmitted reflected-wave data, and a step of causing an information processing device electrically connected to the at least two antennas to perform information processing on the reflected-wave data.

The fixing force evaluation method of the present embodiment includes the natural frequency measurement step of measuring the natural frequency of the stator in which the tooth portions and the stator coil are fixed by the insulating paper, and the fixing force evaluation step of evaluating that the fixing force of the insulating paper is larger, when the natural frequency of the stator measured in the natural frequency measurement step is equal to more than a predetermined determination frequency, compared to when the natural frequency is lower than the determination frequency. Thus, since the fixing force of the insulating paper is evaluated in the fixing force evaluation step based on the natural frequency of the stator measured in the natural frequency measurement step, the fixing force of the insulating paper can be evaluated by measuring the natural frequency of the stator without destroying the stator.

An inspection device is disclosed herein. The inspection device may comprise: a support structure; a motor; a shaft operably coupled to the motor, the shaft extending from a first side of the support structure to a second side of the support structure, the shaft configured to couple to a bladed rotor; an optical device moveably coupled to the support structure; and a broad-band energy source configured to generate acoustic energy through the bladed rotor during inspection.
