A drone includes a body and motors or drives on the body which allow the drone to fly. The drone has two sensors, for steering and for avoiding collisions, and the sensors are each mounted on a servo. The drone also has a camera. A method for avoiding collisions of the drone includes the combination of two detectable 180° hemispheres of the two sensors such that the entire surroundings of the drone is detectable.

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.

An inspection vehicle which is designed to be inserted into the air gap between a rotor and a stator of an electrical machine, in particular of a generator, and to be moved on the substantially cylindrical outer circumference of the rotor in order to inspect the outer circumference of the rotor and/or the inner circumference of the stator for damage.

Inspection vehicle

A test device for a destruction-free test of rotationally symmetrical objects, in particular rotors of gas or steam turbines. The test device has at least three elongated skid bodies which extend in the circumferential direction and parallel to one another, which are interconnected, and which define contact surfaces for positioning on the circumferential surface of the object to be tested, wherein a test body receiving area for an ultrasonic test probe is provided at least on the center skid body.

Test device

A test robot for testing slot breech wedges, which are provided on the outer periphery of a rotor of a generator, the rotor being surrounded by a stator, with a chassis, which receives a drive system, a position detection device, a controller, which controls the drive system based on data captured by the position detection device, magnets attached to the chassis, which are positioned and designed such that the magnets adherently hold the chassis to a magnetic substrate, at least one ultrasound test head, which is freely accessible from the underside of the chassis and is movable upward and downward, and at least one couplant application component, which is provided on the chassis and is associated with the ultrasound test head.

A measuring assembly for detecting the wall thickness of a pipe, including an ultrasonic probe and a testing head with a main element which receives an ultrasonic probe and the lower face of which defines a main element support surface is provided. The testing head has two wing elements, the lower face of each of which defines a wing element support surface and which are held on the main element in a pivotal manner about pivot axes extending substantially parallel to one another in a longitudinal direction such that the wing element support surfaces can be moved towards each other and away from each other. The wing elements are connected via synchronizing means such that the pivotal movements of the wing elements about the corresponding pivot axes are carried out in a synchronous manner. An associated method is also provided.

A milling device is provided, having a milling tool that rotates about a tool rotation axis, wherein the milling device has a slide, and in that the milling tool is held on a pivot axis that extends transversely, in particular perpendicular, to the tool rotation axis and through the slide, wherein the slide is designed and the position of the milling tool is selected such that, during milling, a traversing movement is effected by manually moving the slide and advance is effected by pivoting the milling tool about the pivot axis. Also provided is a method for milling within a slot of a component, in particular within a blade root receiving slot of a turbomachine, using a milling device.

A measurement method for early detection of damage to a blade of an impeller of a turbine is provided. During operation, in a rotational direction of the blade along a circumference which surrounds the impeller, at a plurality of points, in each case a plurality of magnetic fields are generated next to one another substantially in an oscillation direction of the blade, which magnetic fields are influenced by a tip of a turbine blade during transit. Positional values of the tip are detected by at the plurality of points. A positional profile of the turbine blade is then formed from the positional values and a frequency is determined from the positional profile. The frequency is compared with defined frequency values. An alarm event is recognized in case of a sudden and/or pronounced change in the frequency. In addition, a turbine is provided which is configured to carry out the method.
