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 and assembly for verification of the calibration of a system for non-destructive testing of pieces. The assembly includes an ultrasound probe, a perfect reflector having reference defects, and recording and data processing units. The ultrasound probe scans the perfect reflector and ultrasonic reflections from the reflector are measured by the non-destructive testing system, a recording unit records the measurements, and a data processing unit forms a virtual map of the perfect reflector based on the amplitude and time of flight of the reflections and based on predetermined characteristics of the material of the reflector.

Abstract: A device to hold a piece for an item of equipment for ultrasonic measurement. This device has a hollow body, which is substantially tubular, a first end of which can be applied against a surface of the piece and a second opposite end can be connected to a suction element. The hollow body is made from rigid material and the device includes a peripheral joint associated with the first end.

Abstract: This disclosure relates to a method for the nondestructive testing, using laser ultrasonics, of a composite part having a fibrous reinforcement in a resin that optically scatters the laser, includes: a) taking a measurement of the thickness of the resin of the part on the surface that is illuminated during the laser shot, which is capable of generating a thermoelastic effect in said resin and which is referred to as an ultrasonic laser shot; b) adjusting the power of the laser of said ultrasonic shot on the basis of the thickness measurement carried out in step a) so as to eliminate any risk of a flash on the reinforcements; and c) producing the ultrasonic laser shot at the power determined during step b). The device used for implementing the method comprises a combined photoacoustic imaging and low time-coherence interferometry (OCT) system.
