Download or read book Opportunities for Systems Engineering to Contribute to Durability and Damage Tolerance of Hybrid Structures for Airframes written by J. R. Gebman and published by RAND Corporation. This book was released on 2008 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structures making up airframes must be durable and damage tolerant, and the means of ensuring that they are have long been well defined for structures made of metal. But a host of new hybrid materials, some of which contain no metal, are now being used, and these can present new damage mechanisms that engineers must address. The Air Force has established a general approach to airframe durability and damage tolerance. The author examines that approach and considers ways it will need to adapt for the new materials. Given the variety of materials, processes, and end uses involved, the engineering effort will necessarily involve multiple specialties. In these circumstances, the tailoring process could benefit from the efforts of systems engineers. The report addresses both technical and programmatic concerns and identifies opportunities for materials and structural engineers to collaborate with systems engineers. Finally, it offers a framework for collaboration.

Download or read book New Materials for Next Generation Commercial Transports written by Committee on New Materials for Advanced Civil Aircraft and published by National Academies Press. This book was released on 1996-03-29 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life. The committee investigated the new materials and structural concepts that are likely to be incorporated into next generation commercial aircraft and the factors influencing application decisions. Based on these predictions, the committee attempted to identify the design, characterization, monitoring, and maintenance issues that are critical for the introduction of advanced materials and structural concepts into future aircraft.

Download or read book Optimum Composite Structures written by Karam Maalawi and published by BoD – Books on Demand. This book was released on 2019-01-30 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of optimum composite structures is a rapidly evolving field and intensive research and development have taken place in the last few decades. Therefore, this book aims to provide an up-to-date comprehensive overview of the current status in this field to the research community. The contributing authors combine structural analysis, design and optimization basis of composites with a description of the implemented mathematical approaches. Within this framework, each author has dealt with the individual subject as he/she thought appropriate. Each chapter offers detailed information on the related subject of its research with the main objectives of the works carried out as well as providing a comprehensive list of references that should provide a rich platform of research to the field of optimum composite structures.

Download or read book NASA Aeronautics Research written by National Research Council and published by National Academies Press. This book was released on 2008-07-30 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2006, the NRC published a Decadal Survey of Civil Aeronautics: Foundation for the Future, which set out six strategic objectives for the next decade of civil aeronautics research and technology. To determine how NASA is implementing the decadal survey, Congress mandated in the National Aeronautics and Space Administration Act of 2005 that the NRC carry out a review of those efforts. Among other things, this report presents an assessment of how well NASA's research portfolio is addressing the recommendations and high priority R&T challenges identified in the Decadal Survey; how well NASA's aeronautic research portfolio is addressing the aeronautics research requirements; and whether the nation will have the skilled workforce and research facilities to meet the first two items.

Download or read book Application of Lightweighting Technology to Military Aircraft Vessels and Vehicles written by National Research Council and published by National Academies Press. This book was released on 2012-04-27 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lightweighting is a concept well known to structural designers and engineers in all applications areas, from laptops to bicycles to automobiles to buildings and airplanes. Reducing the weight of structures can provide many advantages, including increased energy efficiency, better design, improved usability, and better coupling with new, multifunctional features. While lightweighting is a challenge in commercial structures, the special demands of military vehicles for survivability, maneuverability and transportability significantly stress the already complex process. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft assesses the current state of lightweighting implementation in land, sea, and air vehicles and recommends ways to improve the use of lightweight materials and solutions. This book considers both lightweight materials and lightweight design; the availability of lightweight materials from domestic manufacturers; and the performance of lightweight materials and their manufacturing technologies. It also considers the "trade space"-that is, the effect that use of lightweight materials or technologies can have on the performance and function of all vehicle systems and components. This book also discusses manufacturing capabilities and affordable manufacturing technology to facilitate lightweighting. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft will be of interest to the military, manufacturers and designers of military equipment, and decision makers.
