Title

Investigation of Methods for Determining Actual Flaw Size in Materials by Nondestructive Ultrasonic Means, Part II.

Description

The work effort under Contract AF 33(161)-7279, Supplement S2(61-1519) was directed toward the development and evaluation of techniques for determining actual flaw size, orientation and geometry in materials by nondestructive ultrasonic means. The program led to the development of a breadboard instrument capable of presenting an isometric, 3-dimensional, volumetric projection of inconsistencies in metal parts. The three-dimensional display of the material was achieved by the design of a special mechanical manipulator and presentation system employing a single oscillating transducer.

With theory and practicality thus demonstrated, attention to refinements to increase the inspection rate and improve information display for in-process viewing and permanent recording was undertaken which led to the development of a fully operational self-contained nondestructive testing instrument. This new instrument represents a new technology using sound beam properties in materials as operating parameters to produce an isometric presentation on a cathode ray tube. The end result is an operational instrument capable of rapid scan rates and a multipurpose display system for setup, analysis by in-process viewing, and flaw area localization.
