Problems solved by technology

This can be difficult and time consuming
[0009] Another problem with the device of WO'218 is that in order to effectively ultrasonically couple the array to the workpiece, a separate water supply is required to create a water film between the coupling part and the workpiece
This can be problematic for local pressure on piezoelectric array elements, in particular, can adversely affect their signal characteristics

Embodiment Construction

[0060] Figures 1 to 4d A first ultrasonic inspection probe 100 is shown in . The probe 100 includes a housing 102 , a first handle 104 , a second handle 106 and a rotary encoder 108 . The frame 102 includes a generally curved cross-section and a prismatic body 116 . The body 116 includes a first planar portion 110 , a 90-degree rounded portion 112 , and a second planar portion 114 . A planar portion 110 and a planar portion 114 extend from either end of the rounded portion 112 .

[0061] The probe 100 is configured to move along the elongated rounded workpiece in the axial direction of the rounded portion 112 . The terms “axial” and “radial” are used herein with respect to the radius 112 .

[0062] The main body 116 defines a workpiece facing surface 118 on one side and a frame loading surface 120 on an opposite side. In the illustrated embodiment, the body 116 has a female workpiece facing surface adapted to guide a male workpiece. It should be appreciated that the bod...

Abstract

An ultrasonic inspection tool ( 100; 200} has a chassis ( 102; 202} with a two part body ( 1 16; 216), an aperture ( 130; 230) for providing a clear Sine of sight between an array { 146; 246) and a workpiece, and a series of feet (134, 136: 272, 274, 276, 278., 280, 282) for sliding along the workpiece.

Description

technical field [0001] The present invention relates to an improved ultrasonic inspection tool. More specifically, the present invention relates to an ultrasonic inspection tool utilizing a flexible array to account for dimensional variability of rounded components. Background technique [0002] By rounded parts we mean parts with curved or circular segment cross-sections. Such components typically include a radius that extends 90 degrees, with planar flanges extending from either end of the radius, perpendicular to each other. Aircraft parts such as stringers or spars are examples of rounded parts. [0003] Composite rounded parts will have various features within the radius area. For example, fiber waviness, delamination, and porosity can adversely affect the mechanical properties of the material. Therefore, it has to be designed to increase the material thickness, thereby increasing the weight and cost of the part. This is not expected. [0004] Traditional methods ...
