Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this 2-year program was the development of a reliable nondestructive method of detecting cracks under installed fasteners, emphasizing improvement of the ultrasonic shear wave method. The program included the implementation of the developed method into a system suitable for on-line inspection of airplanes. The development effort proceeded in four main areas: ultrasonic fastener-hole scanning techniques, display of test information, identification of transducer requirements, and portable-scanner design.

This book was released on 2012-12-06 with total page 2093 pages. Available in PDF, EPUB and Kindle. Book excerpt: These Proceedings, consisting of Parts A and B, contain the edited versions of most of the papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at University of San Diego, San Diego, CA, on July 27 to August 1, 1997. The Review was organized by the Center for NDE at Iowa State University, in cooperation with the Ames Laboratory of the USDOE, the American Society of Nondestructive Testing, the National Institute of Standards and Technology, the Federal Aviation Administration, and the National Science Foundation IndustrylUniversity Cooperative Research Centers. This year's Review of Progress in QNDE was attended by approximately 370 participants from the US and many foreign countries who presented a total of approximately 350 papers. As usual, the meeting was divided into 36 sessions with four sessions running concurrently. The Review covered all phases of NDE research and development from fundamental investigations to engineering applications and inspection systems, and methods of inspection science from acoustics to x-rays. The Review continues to experience some fluctuations in size, mostly under pressure from a decrease in funding for NDE research at the US Federal level, but increased participation from foreign laboratories has more than made up the difference. The Review is ideally sized to permit a full-scale overview of the latest developments in a collegial atmosphere that most participants favor. The opening plenary session this year concentrated on advances in imaging technologies and methodologies that have been made in recent years. Dr. K.

Download or read book Civil and Military Airworthiness written by Kyriakos I. Kourousis and published by MDPI. This book was released on 2020-05-27 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Airworthiness, as a field, encompasses the technical and non-technical activities required to design, certify, produce, maintain, and safely operate an aircraft throughout its lifespan. The evolving technology, science, and engineering methods and, most importantly, aviation regulation, offer new opportunities and create, new challenges for the aviation industry. This book assembles review and research articles across a variety of topics in the field of airworthiness: aircraft maintenance, safety management, human factors, cost analysis, structures, risk assessment, unmanned aerial vehicles and regulations. This selection of papers informs the industry practitioners and researchers on important issues.
Download or read book Review of Progress in Quantitative Nondestructive Evaluation written by Donald Thompson and published by Springer. This book was released on 1982-09 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perhaps the largest symposium held annually in the area of quantitative nondestructive evaluation is the one which resulted in this book. The 1981 Review of Progress in Quantitative Nondestructive Evaluation (NDE) was held August 2-7 at the University of Colorado in Boulder. While the review was sponsored by the Materials Laboratory of the Air Force Wright Aeronautical Laboratories and the Defense Advanced Research Projects Agency as part of their sponsored research conducted through the Ames Laboratory of the U.S. Department of Energy, nearly 300 attendees, representing other government agencies and the industrial and university communities as well, participated in the technical presentations, poster sessions and discussions. The program emphasized various areas of interest in quantitative NDE, including topics related to the development of quantitative ultrasonic and eddy current techniques, other emerging techniques, considerations of im provements needed in the probability of flaw detection, and engineering applications which follow from technology transfer of research results. An example of this transfer is the utilization of the Born inversion algorithm for flaw sizing. The keynote address, "NDE--A Key to Enhanced Producti vity," was deli vered by Dr. Norman Tallan, Chief Scientist at the Air Force Materials Laboratory. Dr. Tallan's presentation concerned the importance and potential pay-off of moving the NDE inspection procedure forward to provide in-process inspection and control for manufacturing. This step requires the utilization of concepts and research pursued in quantitative NDE activities and the initiation of other key steps.

Download or read book Aeronautical Applications of Non destructive Testing written by Abbas Fahr and published by DEStech Publications, Inc. This book was released on 2013-12-05 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive guide to the basic principles and applications of non-destructive testing methods for aircraft system and components: airframe, propulsion, landing gear and more Provides detailed analysis of the advantages and disadvantages of major NDT methods Important for design, inspection, maintenance, repair, corrosion protection and safety This critical book is among the first to provide a detailed assessment of non-destructive testing methods for the many materials and thousands of parts in aircraft. It describes a wide variety of NDT techniques and explains their application in the evaluation and inspection of aerospace materials and components ranging from the entire airframe to systems and subsystems. At the same time the book offers guidance on the information derived from each NDT method and its relation to aircraft design, repair, maintenance and overall safety. The book covers basic principles, as well as practical details of instrumentation, procedures and operational results with a full discussion of each method's capabilities and limitations as these pertain to aircraft inspection and different types of materials, e.g., composites and metal alloys. Technologies covered include: optical and enhanced optical methods; liquid penetrant, replication and magnetic particle inspection; electromagnetic and eddy current approaches; acoustics and ultrasonic techniques; infrared thermal imaging; and radiographic methods. A final section is devoted to NDT reliability and ways the probability of detection can be measured to establish inspection intervals.

Download or read book Detection Reliability for Small Cracks Beneath Rivet Heads Using Eddy current Nondestructive Inspection Techniques written by Floyd W. Spencer and published by . This book was released on 1998 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced inspection technology that is emerging from the laboratory is generally far superior to the less capable systems around which aircraft inspections are designed. In light of the very conservative nature of these inspection designs, it is apparent that today's advanced technology is being employed at only a fraction of its full potential. In order to assess the full potential of advanced eddy-current inspection technology on representative aircraft applications, the FAA's Airworthiness Assurance Nondestructive Inspection Validation Center (AANC) was tasked to assess the full capability of several advanced systems. The task involved inspections of several rivet skin splices-representative of actual aircraft structure-containing cracks ranging from 0.040-, 0.060-, and 0.080-inch standards, and thresholds were set to the lowest reasonable level for the particular system. The results demonstrated that some of the systems were able to reliably detect cracks as small as 0.040 inch with false call rates remained less than 1%.
