Abstract: A method for checking an ultrasound probe which includes taking a measurement using the probe bonded to the part and in comparing the results with a prerecorded reference recording, and, if there is divergence, in using a tool previously used to produce the reference recording to identify whether the probe is not bonded or not working properly. Such a checking method makes it possible to check the state of the probe without having to remove it.

Abstract: A flying drone for inspecting surfaces able to reflect light has a lighting device formed of two light sources each having a shape that is elongate in a longitudinal direction of each of the light sources, two first image acquisition devices, and a second image acquisition device between the two first image acquisition devices. The two light sources are respectively between the second image acquisition device and each of the first image acquisition devices. The flying drone allows effective detection of dents in surfaces by analyzing specular reflections, by the lighting device and of the first image acquisition devices, and effective detection of superficial defects on surfaces by the second image acquisition device, with the lighting device switched off.

Abstract: A computer system is provided for processing ultrasonic data of an ultrasonic probe applied to an area of an aircraft component that includes carbon fiber reinforced polymer. C-scan data is obtained and a preliminary mesh is defined over the C-scan data by taking into account the underlying structural or mechanical characteristics of the analyzed component. The mesh is further refined and data gathered for each mesh cell. A heat map is generated based on the mesh.

Abstract: A method for the non-destructive ultrasonic testing of a part by the analysis of echoes returned by the part in response to the emission of an ultrasonic wave via an ultrasonic transducer, includes a step of determining a variable gain curve and a step of correcting the amplitude of the echoes returned by the part according to the variable gain curve and the moments of reception of the echoes. The method further includes steps of: producing a wave function representative of an ultrasonic transducer; producing transfer functions Fm representative of the frequency responses of reference samples Rm of the material forming the part; and calculating reference attenuation values between the wave function and the results of calculations of filtering of the wave function by the respective transfer functions Fm of the reference samples Rm.

Abstract: A detection wire cutter including a conducting wire mechanically secured to a structure that is to be monitored. This wire is electrically powered at one end and at another end feeds back an electrical voltage corresponding to the power supplied, provided that the structure that is to be monitored has not undergone unacceptable mechanical damage. As an improvement, two arrays of wires extending over flat supports in two directions in space are proposed. Each array is powered by a distinct network electrical supply. The two networks extend in layers, with parallel wire portions. The position of a crack does not impede the passage of current between certain terminals, but certain other terminals will no longer receive any current because the crack has broken a network supply general connection between the connection of one wire and that of another.

Abstract: A method of simulating non-destructive testing with the aid of at least one probe. The method comprises the steps of measuring inspection parameters, in particular related to the position of the probe in space and generating synthetic signals corresponding to a non-destructive testing operation.
