摘要： A gas turbine with at least one stationary stator blade and at least one rotor blade that can be rotated during operation is provided. The gas turbine has at least one optical waveguide embedded into a first rotor blade. The optical waveguide is oriented such that thermal radiation of a region of the first stator blade can be detected by the optical waveguide. An analyzing device is designed to analyze the thermal radiation and to ascertain the temperature of the region of the first stator blade, the temperature being ascertainable along a path from which the radiation is emitted during the rotation of the first rotor blade.

摘要： A device for determining distance between a rotor blade and a wall of a gas turbine surrounding the rotor blade is provided. A waveguide guides and emits electromagnetic waves in the direction of the rotor blade through a waveguide opening facing the rotor blade. The electromagnetic waves are injected into the waveguide and reflected portions of the electromagnetic waves are received. An evaluation unit compares the phase of the electromagnetic waves to be injected with the phase of the reflected portions of the electromagnetic waves and determines phase comparison values for every frequency and the distance is determined based on the phase comparison values. The waveguide includes two waveguide segments made from different materials having temperature stability and damping capacity increasing in the direction from the segment connected to the unit for injecting the waves to the segment having the waveguide opening.

摘要： A method determines the layer thickness of a TBC coating of at least one blade of a non-positive-displacement machine. To this end, at least one electromagnetic wave is emitted to the surface of the at least one blade, the at least one electromagnetic wave is then at least partially reflected by the at least one blade, and the reflected portion of the at least one electromagnetic wave is received and subsequently processed. In addition, the at least one electromagnetic wave is emitted with a frequency matched to the layer thickness of the TBC coating, and the phase of the at least one electromagnetic wave is compared with the phase of the at least one received electromagnetic wave. The at least one emitted electromagnetic wave undergoes a phase change during reflection and the layer thickness of the TBC coating is determined by the phase comparison.

The electromagnetic waves are reflected, at least in part, by at least one rotating blade. The reflected portions of the electromagnetic waves are received by at least one receiving means and the temperature of the surface coating of the rotating blades is determined from a distribution of intensity of the received electromagnetic waves. The invention also relates to a method for determining the temperature of a surface coating of guide vanes mounted in a rotationally fixed manner in a non-positive-displacement machine with a housing, and to a device for carrying out the method.
