The Middle Ground of the NDE R&D Spectrumence and technology and some approaches for fostering R&D in such a situation. Next, we want to describe the objective of the DARPA, Air Force (and now Navy) core program for developing a science base for NDE and how it has evolved during the past two years. Some changes have indeed taken place; we

Probabilistic Consequences of Imperfect NDErcraft and the U. S. Air Force. The Retirement-for-Cause concept is addressed, conventional Monte Carlo modeling techniques are explained, and an alternative approach developed at Pratt and Whitney is presented. Next, a simplified non-ideal Non-Destructive-Evaluation (NDE) model with fixed probabili

Improving NDE Through Multiple Inspectionstecting a given crack length depends on many factors, such as the location, orientation and shape of the flaw, materials, inspectors, inspection environments, etc. As a result, the probability of detection (POD) for all cracks of a given length has been used in the literature to define the capabilit

Detection of Flaws Below Curved Surfacesurved surfaces. The model includes noise terms to describe electrical noise, scatterer noise and echo noise as well as effects of attenuation, diffraction and Fresnel loss. An experimental procedure for calibrating the noise terms of the model was developed. Experimental measurements were made on a
