Abstract
A method for simulating in real-time the ultrasonic inspection of flaws in power plant components such as piping stores the X, Y and skew data relating to a specific waveform and a specific flaw in a unique format in a multi-disk rotational data storage. The skew angles are respectively stored on one side of a disk with the X-axis data relating to tracks on the disk and the Y-axis data to sectors on the disk. In this manner waveform data of several bytes which represent a defect or flaw can be retrieved and displayed to the user of this simulation system. A RAM is utilized as a cache memory.
