摘要： An improved ultrasonic inspection system is provided which allows ultrasonic inspection to be performed using either of two ultrasonic frequencies and which also provides improved system sensitivity and dynamic range. In operation, the system produces two signals, one an amplified receive transducer signal and the other an attenuated receive transducer signal. Each signal is converted into a logarithmic representation. The two logarithmic representations are selectively provided to a read-only memory, which operates to output a signal corresponding to the receive transducer signal. Means are also provided which allows the system to use either of two ultrasonic frequencies.

摘要： Method and apparatus for measuring the waviness of an aerodynamic surface includes a sensing unit that provides a plurality of data values which indicate the vertical deflection of a sensor at predetermined positions along the surface. A microprocessor receives the plurality of data values and processes the values in accordance with a method to determine the waviness of the surface. The microprocessor determines which of the plurality of data points have a convex curvature with respect to the data points to which it is adjacent and uses the convex data points to define lines which are tangent to the surface. The tangent lines are used to identify waves in the surface. The depth and length of each wave is determined from the tangent lines and the waviness calculation performed in accordance with a predetermined waviness formula.

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.
