摘要： Ultrasonic testing on a part includes scanning the part while performing pulse echo and through transmission ultrasonic testing on the part; converting pulse echo data into time of flight (TOF) and amplitude channels, and converting through transmission data into a data representation that identifies porosity. The testing further includes analyzing the pulse echo TOF to identify locations of any anomalies in the part, and using loss of back (LOB) at each of the identified locations to discriminate low porosity from other anomalies.

摘要： A probe (20) that inspects a countersunk hole (21) in a conductive body, such as an aircraft part (22), is provided. A plurality of nested cylinders form an electrode cartridge (54) with a countersink portion (74) having a frustoconical shape and a hole portion (76) having a cylindrical shape. A plurality of lower hole electrode strips (72) are mounted on a lower hole cylinder (110) and a plurality of upper hole electrode strips (70) are mounted on an upper hole cylinder (116). A plurality of lower countersink electrode strips (68) are coupled to a lower countersink cylinder (124) and a plurality of upper countersink electrode strips (66) are coupled to an upper countersink cylinder (132). A dielectric layer (64) covers a plurality of measuring electrode tips (67, 69, 71 and 73) and an outer surface (150) of the hole and countersink portions (76 and 74). A grounding electrode (158) is mounted on the upper hole cylinder ( 116). A ground wire (162) is coupled to the grounding electrode (158) and extends beyond the dielectric layer (64). When probe (20) is inserted into the countersunk hole (21), the countersunk hole (21) is grounded by the ground wire (162). A charging current applied to the measuring electrode strips (66, 68, 70 and 72) in a sequential manner, causes the measuring electrode tips (67, 69, 71 and 73) form fringe field capacitors with the ground wall of the countersunk hole (21). The fringe field capacitors charge up at a rate dependent, in part, upon the distance between the probe (20) and the wall of the countersunk hole (21). Sufficient rate measurements are made of the distance between the probe (20) and the wall of the countersunk hole (20) to permit another device (30) to determine whether the geometry and orientation of the countersunk hole (21) are within engineering specifications.

摘要： A sensor including an eddy current loop and an ultrasonic transducer transmitting along a common axis is placed against a second surface of a graphite/epoxy composite structure whose first surface has been formed over the surface of a steel model. The eddy current coil can produce a signal measuring the separation between the sensor and the surface of the steel model, and the ultrasonic transduer can produce a signal representing the thickness of the graphite/epoxy composite panel. The distance and thickness signals are passed to electrical circuitry that computes their difference and displays the calibrated result as a measure of the gap between the steel model and the graphite/epoxy tool.

摘要： A multi-sensor NDI probe having means for self-alignment of the NDI sensors in conjunction with the movement of the sensor suite along the length of a hollow elongated stiffener having a rounded cap. The apparatus comprises a large-radius curved ultrasonic transducer array with cylindrical focus, which provides complete coverage for the rounded cap, two small-radius convex curved transducer arrays for NDI of the lower outside radii, and two linear transducer arrays for NDI of the sides of the stiffener. The five transducer arrays are supported by respective compliant assemblies which facilitate proper adjustment of the location (i.e., position and orientation) of the transducer arrays during scanning. The positions of the transducer arrays are adjusted to account for geometric variations in the stiffener.
