Book excerpt: Determining deterioration characteristics of the Space Shuttle crew escape system pyrotechnic components loaded with hexanitrostilbene would enable us to establish a hardware life-limit for these items, so we could better plan our equipment use and, possibly, extend the useful life of the hardware. We subjected components to accelerated-age environments to determine degradation characteristics and established a hardware life-limit based upon observed and calculated trends. We extracted samples using manufacturing lots currently installed in the Space Shuttle crew escape system and from other NASA programs. Hardware included in the study consisted of various forms and ages of mild detonating fuse, linear shaped charge, and flexible confined detonating cord. The hardware types were segregated into 5 groups. One was subjected to detonation velocity testing for a baseline. Two were first subjected to prolonged 155 F heat exposure, and the other two were first subjected to 255 F, before undergoing detonation velocity testing and/or chromatography analysis. Test results showed no measurable changes in performance to allow a prediction of an end of life given the storage and elevated temperature environments the hardware experiences. Given the lack of a definitive performance trend, coupled with previous tests on post-flight Space Shuttle hardware showing no significant changes in chemical purity or detonation velocity, we recommend a safe increase in the useful life of the hardware to 20 years, from the current maximum limits of 10 and 15 years, depending on the hardware.

Book excerpt: This book presents a history of shock compression science, including development of experimental, material modeling, and hydrodynamics code technologies over the past six decades at Sandia National Laboratories. The book is organized into a discussion of major accomplishments by decade with over 900 references, followed by a unique collection of 45 personal recollections detailing the trials, tribulations, and successes of building a world-class organization in the field. It explains some of the challenges researchers faced and the gratification they experienced when a discovery was made. Several visionary researchers made pioneering advances that integrated these three technologies into a cohesive capability to solve complex scientific and engineering problems. What approaches worked, which ones did not, and the applications of the research are described. Notable applications include the turret explosion aboard the USS Iowa and the Shoemaker-Levy comet impact on Jupiter. The personal anecdotes and recollections make for a fascinating account of building a world-renowned capability from meager beginnings. This book will be inspiring to the expert, the non expert, and the early-career scientist. Undergraduate and graduate students in science and engineering who are contemplating different fields of study should find it especially compelling.

This book was released on 2003-01-30 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book investigates the synthesis, kinetics, and thermal decomposition properties and processing of energy-producing materials used in propellants, explosives, pyrotechnic, and gas-generating compositions. Thermal Decomposition and Combustion of Explosives and Propellants provides several mechanisms and stages for the thermal decomposition and combustion reactions of most flammable compounds and their mixtures, such asaliphatic and aromatic nitrocompounds, nitramines, nitroesters, organic azides, furazanes, tetrazols, difluoroamines, polynitrous heterocycles, and onium salts. The authors examine the classic problem of the dependence of explosive activity on molecular structure, using applications to predict the stability, compatibility, and the stabilization of explosives and propellant components. They also offer experimental results examining factors such as subsurface decomposition, evaporation, and dispersion of materials, which can be used to control combustion of condensed systems. Providing several approaches to stability, safety, and controlled combustion of flammable substances, Thermal Decomposition and Combustion of Explosives and Propellants is a multi-dimensional resource for graduate students, researchers and professionals interested in chemical kinetics, the combustion and synthesis of high-energy materials, criminal forensics, and the field of explosives, powders, and solid rocket propellants.

Book excerpt: Impact and Explosion: Structural Analysis and Design presents a comprehensive study of the structural dynamics of impact and explosion by providing a survey of types of aircraft, missiles, bombs, and detonators. Impact dynamics, including empirical models developed for different materials, water surfaces, and soil/rock mediums, is discussed. Other topics include load time history; explosion dynamics related to material damage capabilities; dynamic finite elements with provisions for impact and explosions; a discussion of solution procedures, acceleration, and convergence criteria; methods for designing structures resistant to impact and explosions; and how damage results due to impact or explosions. Case histories, comparative studies, numerous examples, appendices, and extensive references reinforce information presented in this important book for engineers and researchers working in government and private industry laboratories concerned with blast or impact loading effects on structures. Small firms that deal with impact loading (e.g., automobile collisions) will also find this book valuable.

Available in PDF, EPUB and Kindle. Book excerpt: Incorporation of particular components with specialized properties allows one to tailor the end product's properties. For instance, the sensitivity, burning behavior, thermal or mechanical properties or stability of energetic materials can be affected and even controllably varied through incorporation of such ingredients. This book examines particle technologies as applied to energetic materials such as propellants and explosives, thus filling a void in the literature on this subject. Following an introduction covering general features of energetic materials, the first section of this book describes methods of manufacturing particulate energetic materials, including size reduction, crystallization, atomization, particle formation using supercritical fluids and microencapsulation, agglomeration phenomena, special considerations in mixing explosive particles and the production of nanoparticles. The second section discusses the characterization of particulate materials. Techniques and methods such as particle size analysis, morphology elucidation and the determination of chemical and thermal properties are presented. The wettability of powders and rheological behavior of suspensions and solids are also considered. Furthermore, methods of determining the performance of particular energetic materials are described. Each chapter deals with fundamentals and application possibilities of the various methods presented, with particular emphasis on issues applicable to particulate energetic materials. The book is thus equally relevant for chemists, physicists, material scientists, chemical and mechanical engineers and anyone interested or engaged in particle processing and characterization technologies.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced energetic materialsâ€"explosive fill and propellantsâ€"are a critical technology for national security. While several new promising concepts and formulations have emerged in recent years, the Department of Defense is concerned about the nation's ability to maintain and improve the knowledge base in this area. To assist in addressing these concerns, two offices within DOD asked the NRC to investigate and assess the scope and health of the U.S. R&D efforts in energetic materials. This report provides that assessment. It presents several findings about the current R&D effort and recommendations aimed at improving U.S. capabilities in developing new energetic materials technology. This study reviewed U.S. research and development in advanced energetics being conducted by DoD, the DoE national laboratories, industries, and academia, from a list provided by the sponsors. It also: (a) reviewed papers and technology assessments of non-U.S. work in advanced energetics, assessed important parameters, such as validity, viability, and the likelihood that each of these materials can be produced in quantity; (b) identified barriers to scale-up and production, and suggested technical approaches for addressing potential problems; and (c) suggested specific opportunities, strategies, and priorities for government sponsorship of technologies and manufacturing process development.
