Patent number: 11995815Abstract: A method uses a flexible endoscope to inspect one or more hard-to-reach components of a gas turbine. The flexible endoscope has at least one image capture unit, which is configured to capture visual image information and associated 3D data, and which is located at a free end of the flexible endoscope. The method includes: introducing the flexible endoscope through an inspection opening; capturing the visual image information and the associated 3D data by the at least one image capture unit; comparing the captured 3D data to a 3D model of a component to be examined, and based on the comparison, ascertaining a relative pose of the at least one image capture unit in relation to the component; and texturing the 3D model with the visual image information captured by the at least one image capture unit, in accordance with the ascertained relative pose of the image capture unit.Type: GrantFiled: December 12, 2019Date of Patent: May 28, 2024Assignee: LUFTHANSA TECHNIK AGInventors: Jan Oke Peters, Michael Thies, Thorsten Schueppstuhl, Werner Neddermeyer, Sven Rasche, Tomas Domaschke, Maik Dammann, Mattes Schumann, Jens-Peter Tuppatsch, Soenke Bahr

Patent number: 11940351Abstract: A borescope is for optically inspecting gas turbines of aircraft engines. The borescope having an electronic image capture unit as a borescope objective at an end of a shaft, which is suitable for insertion into a borescope opening and configured for accurate positioning of the borescope objective relative to the borescope opening and through which data lines and supply lines for the image capture unit are guided. The image capture unit has: two spaced apart image capture sensors, recording cones of which overlap in a specified recording plane forming a recording region, in such a way that image data of the two image capture sensors are configured to be processed into 3-D data by way of triangulation.Type: GrantFiled: January 14, 2020Date of Patent: March 26, 2024Assignee: LUFTHANSA TECHNIK AGInventors: Jan Oke Peters, Michael Thies, Sven Rasche, Tomas Domaschke, Thorsten Schueppstuhl, Werner Neddermeyer, Soenke Bahr

Publication number: 20240085170Abstract: A method for assessing a wall of a depression, particularly a bore, in a workpiece. The method requires that a light beam in the depression is deflected so that at least two regions of the at least one wall portion are illuminated, and in that, by means of the at least two regions, reflected light is guided along the first axis out of the depression and is used outside the depression for determining the geometry and/or reflectivity of the at least one wall portion. The determination of the geometry or reflectivity is carried out interferometrically and/or wherein in each region for at least 250 pixels, at least one distance value and/or at least one intensity and/or reflectivity value is detected, and/or wherein the regions and/or the at least one light beam each has an area of at least 0.1 mm2.Type: ApplicationFiled: September 12, 2023Publication date: March 14, 2024Applicant: 3D.aero GmbHInventors: Werner NEDDERMEYER, Tim HARMS, Sönke BAHR, Tobias FLÜH, Tomas DOMASCHKE

METHOD FOR ASSESSING THE RESULT OF A SURFACE TREATMENT PERFORMED ON A WORKPIECE BY PARTICLE BLASTING
Publication number: 20240068959Abstract: Methods for assessing the result of a surface treatment carried out on a workpiece by particle blasting are disclosed. It is generally common to known automatic methods that they directly determine the covered portion of the surface. Proceeding from the usual definition of the usual 98% degree of coverage as “completely blasted” results in an error in the determination of the corresponding area of 1% to a distortion of the measurement result by 0.98%. In the disclosed method measuring points are identified as not hit by a particle of the particle beam when both a detected surface level is above a level located about a predetermined height threshold value lower than a target level, and a detected gradient falls below a predetermined gradient threshold value.Type: ApplicationFiled: August 22, 2023Publication date: February 29, 2024Applicant: 3D.aero GmbHInventors: Anton JANSSEN, Lars REIMER, Tobias FLÜH, Tomas DOMASCHKE, Michael ERNST -
Publication number: 20230120378Abstract: An apparatus investigates a technical device using a borescope. The apparatus has: a guide tube which is introducible through a borescope opening on the technical device to be inspected using the borescope; and a repeatedly plastically deformable carrier configured to guide a borescope head arranged at one end of the carrier. The guide tube is designed to deform the carrier during the passage of the carrier through the guide tube.Type: ApplicationFiled: March 5, 2021Publication date: April 20, 2023Inventors: Thorsten Schueppstuhl, Lukas Bath, Maik Dammann, Mattes Schumann, Tarek Mostafa, Oliver Neumann, Werner Neddermeyer, Sven Rasche, Tomas Domaschke, Soenke Bahr, Jan Oke Peters, Michael Thies

Patent number: 11301990Abstract: A method for borescope inspection of a component uses a stereo borescope for recording the component. The method includes: generating two stereoscopic partial images by means of the stereo borescope; calculating 3D triangulation data from the two stereoscopic partial images; registering the 3D triangulation data to a 3D CAD reference model of the component captured by the stereo borescope, while determining a projection point; projecting 2D image data determined from the two stereoscopic partial images onto the 3D CAD reference model from the determined projection point; and determining damage by image analysis of the projected 2D image data and by ascertaining deviations of the registered 3D triangulation data vis-à-vis the 3D CAD reference model.Type: GrantFiled: January 14, 2020Date of Patent: April 12, 2022Assignee: LUFTHANSA TECHNIK AGInventors: Jan Oke Peters, Michael Thies, Sven Rasche, Tomas Domaschke, Thorsten Schueppstuhl, Werner Neddermeyer, Soenke Bahr
