Abstract: 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.

Abstract: 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.

Abstract: A borescope includes an electronic image capturing unit having at least one image capturing sensor with a receiving cone at a first end of a shaft, the shaft having a shaft axis and through which data and supply lines for the image capturing unit are led. The image capturing unit is arranged on a rotary head. The rotary head is secured to the first end so as to be rotatable about the shaft axis such that an axis of the receiving cone is not parallel to the shaft axis at the first end and so that the rotating head is arranged to capture a panoramic image.

Abstract: 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.

Abstract: 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.

Abstract: A method for repairing a component constructed in multiple layers from a layer composite material comprises a step of removing material of the layer composite material of the component in the region of damage to the component in order to form a scarfed cutout, such that a scarfed peripheral contour formed from a plurality of layers of the component is formed. Furthermore, fiber-reinforced plastic strips, which exhibit a curable plastic material in an uncured state, are applied in layers in the cutout in order to create a replacement-structure semifinished product that is complementary to and butts against the scarfed peripheral contour of the component. In a further step, the curable plastic material contained in the fiber-reinforced plastic strips is cured in order to create a replacement structure and for joining the replacement structure to the component.

Abstract: An apparatus for processing a component includes a multi-axis positioning device, a processing tool, and a control device for controlling the multi-axis positioning device. The multi-axis positioning device is configured to move the processing tool relative to the component and to move each axis of the processing tool within a corresponding work envelope. The control device is configured to limit the movement of the multi-axis positioning device along or about at least one limited axis within the corresponding work envelope to a subregion or subspace. The multi-axis positioning device and/or the component is configured to move about and/or along an external axis to compensate for the limitation of the movement along or about the limited axis.

Abstract: The invention relates to an apparatus for introducing weakening cuts in a film or skin (24) containing a cutting knife (12) and a support (18) arranged in opposition to the cutting knife, wherein the film or skin can be placed between the support and the cutting knife and borne by the support, and the cutting knife is movable relative to the film or skin. In order to ensure a defined residual wall thickness, the invention proposes that the distance between the cutting knife and the support in the direction of the cutting axis (19) can be designed to be kept constant by a device.
