摘要： A method to laser shock peen articles such as a gas turbine engine rotor blade with first and second oblique laser beams to form pairs of longitudinally spaced apart first and second laser shock peened elliptical spots that are on opposite sides of the article or blade and transversely offset from each other. The oblique laser beams are fired at a portion of the leading or trailing edges of the blade at first and second oblique angles with respect to opposite surfaces of the edge. Another method laser shock peens the leading and trailing edges of gas turbine engine integrally bladed rotors and disks that are blocked by other rows of blades by firing the laser beams at compound angles such that the beams are aimed at the first and second oblique angles with respect to the surfaces of the edge and at a third oblique angle with respect to a rotor axis.

摘要： A specimen is mounted in a multiaxis machine. An eddy current probe is also mounted in the machine for multiaxis movement relative to the specimen. The probe is aligned in situ with a target in the specimen by direct contact therebetween at multiple alignment sites corresponding with a numerical model of the specimen. Eddy current inspection of the target may then be conducted by moving the probe along multiple inspection sites of the target corresponding with the specimen model.

摘要： A real time method for quality control testing of a laser shock peening process of production workpieces by analysis of natural frequency shifts during the laser shock peening process. One particular embodiment includes laser shock peening surface of the production workpiece by firing a plurality of laser beam pulses on the surface and forming a plurality of corresponding plasmas, each one of the plasmas pulses having a duration in which the plasma causes a region having deep compressive residual stresses to form beneath the surface, measuring at least one natural frequency of the workpiece for each of the laser beam pulses, calculating natural frequency shifts from a baseline natural frequency for the measured natural frequencies for at least a portion of the laser beam pulses, and using the natural frequency shifts for accepting or rejecting the workpiece with respect to pass or fail criteria.

摘要： A method for inspecting a component having a surface profile that includes a local minima and a local maxima. The method includes positioning an eddy current probe proximate to a surface of the component to generate a first position indication, positioning the eddy current probe proximate to the surface of the component to generate a second position indication that is different than the first position indication, and interpolating between the first and second position indications to determine a profile of a portion of the surface of the component.

摘要： Omnidirectional eddy current array probes for detecting flaws in a conductive test object generally includes semi-circular wave shaped continuous drive lines in two rows disposed in two layers that are multiplexed for omnidirectional inspection without blind spots. The semicircular wave shaped continuous drive lines are superimposed to form pseudo-circular drive lines, wherein each row of drive lines is offset laterally by a distance preferably equal to a quarter wavelength of the wave pattern. For only parallel and perpendicular flaws, the drive multiplexing is not needed and each row will have only one set of drive lines. In alternate embodiments, there can be square-shaped, oval shaped, rectangular-shaped or other shaped wave patterns as well. Also disclosed are methods for sensing surface flaws and compensating their response.

摘要： A method for detecting small cracks and other anomalies on parts having complex geometries is disclosed. The method includes eddy current inspection incorporating collection of data from multi-frequency eddy current signals. Phase analysis is used to combine the multi-frequency data to enhance the signal to noise ratio of the raw inspection image. The image is then reprocessed using a spatiotemporal filter to correlate with the frequency components of the eddy current flaw signal to separate signals associated with cracks and other flaws at edges that would ordinarily be hidden by edge effect signals.
