Advancements In Energetic Materials And Chemical Propulsion

Written by the scientists who performed the research, this book reports on the progress achieved by the outstanding team of researchers participating in the ONR Propulsion Program. It covers all aspects of the combustion process, from chemical synthesis, reaction pathways of the fuel, and combustor performance to the reduction of emissions, thrust vectoring, and control. The chapter authors discuss the relevant issues, describe their approach and results, and explain how the findings can be extended to practical applications. Richly illustrated and carefully edited for clarity, uniformity, and readability, this book offers a comprehensive survey of the field, from pre- to post-combustion.

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.

Developed and expanded from the work presented at the New Energetic Materials and Propulsion Techniques for Space Exploration workshop in June 2014, this book contains new scientific results, up-to-date reviews, and inspiring perspectives in a number of areas related to the energetic aspects of chemical rocket propulsion. This collection covers the entire life of energetic materials from their conceptual formulation to practical manufacturing; it includes coverage of theoretical and experimental ballistics, performance properties, as well as laboratory-scale and full system-scale, handling, hazards, environment, ageing, and disposal. Chemical Rocket Propulsion is a unique work, where a selection of accomplished experts from the pioneering era of space propulsion and current technologists from the most advanced international laboratories discuss the future of chemical rocket propulsion for access to, and exploration of, space. It will be of interest to both postgraduate and final-year undergraduate students in aerospace engineering, and practicing aeronautical engineers and designers, especially those with an interest in propulsion, as well as researchers in energetic materials.

This book focuses on the combustion performance and application of innovative energetic materials for solid and hybrid space rocket propulsion. It provides a comprehensive overview of advanced technologies in the field of innovative energetic materials and combustion performance, introduces methods of modeling and diagnosing the aggregation/agglomeration of active energetic metal materials in solid propellants, and investigates the potential applications of innovative energetic materials in solid and hybrid propulsion. In addition, it also provides step-by-step solutions for sample problems to help readers gain a good understanding of combustion performance and potential applications of innovative energetic materials in space propulsion. This book serves as an excellent resource for researchers and engineers in the field of propellants, explosives, and pyrotechnics.

To accelerate the potential applications, various works focused on the physical and chemical characteristics through theory, experiments, and simulations of advanced energetic materials (AEMs), including nano-scale energetic materials (nEMs) and micro-scale energetic materials (mEMs). This Special Issue collected comprehensive knowledge on materials synthesis, characterization, combustion, mechanical, detonation, and safety. This Special Issue, Advanced Energetic Materials: Testing and Modeling, explores innovative EMs and EMs ingredients and formulations tests and models. It collected contributions covering recent progress and models of energetic materials in chemical propulsion. Attention was focused on the design, model, properties, and state-of-the-art of this class of thermochemical propulsion devices. A total of 13 papers were selected for publication after a standard peer review process, which summarizes the most recent achievements of famous research groups. Participation of young authors with novel/innovative concepts was especially encouraged, of course, with the assistance of their supervisors.

In this book recent advances in the field of energetic materials are reported. Energetic materials are those chemical compounds which are used for explosions or propulsion of rockets and artillery shells. However, energetic materials are rarely used in their pure form but as a mixture of different other components to enhance their properties. During the usage of these materials, one not only has to worry about danger of unintended explosion or fire, but also about long term health issues associated with handling of these materials because some of them are carcinogenic. Therefore, this book is divided into 4 sections. In the first section, a brief introduction to different terminologies and classification of energetic materials is given. In the second section, articles related to processing related issues of energetic materials are presented. In these articles, authors have described methods for preparing nano-aluminum particles for use as fuel component in the energetic composite formulation, where usage of nano particles not only provides better mixing but it also increases performance. In another article, a coating method is explained. This section also explains the methods for casting energetic materials into desired shapes and methods to calculate usage requirements. In third section, different synthesis methods and crystal structure of energetic materials are presented. In the last section, articles related to computational studies of energetic materials, and reports on health hazards related to them are presented. In the last section, few articles related to environmental and health issues associated with the use of these material are given. In addition, some articles related to computation methods for performance prediction are also presented.

This book offers a comprehensive account of energetic materials, including their synthesis, computational modeling, applications, associated degradation mechanisms, environmental consequences and fate and transport. This multi-author contributed volume describes how armed forces around the world are moving their attention from legacy explosive compounds, which are heat and shock sensitive (thus posing greater challenges in terms of handling and storage), to the insensitive munitions compounds/formulations such as insensitive munitions explosive (IMX) and the Picatinny Arsenal Explosive (PAX) series of compounds. The description of energetic materials focuses on explosives, pyrotechnic compositions, and propellants. The contributors go on to explain how modern generation energetic compounds must be insensitive to shock and heat but at the same time yield more energy upon explosion. Nanoinspired and/or co-crystallized energetic materials offer another route to generate next-generation energetic materials, and this authoritative book bridges a large gap in the literature by providing a comprehensive analysis of these compounds. Additionally, it includes a valuable overview of energetic materials, a detailed discussion of recent advances on future energetic compounds, nanotechnology in energetic materials, environmental contamination and toxicity, assessment of munitions lethality, the application quantitative structure–activity relationship (QSAR) in design of energetics and the fate and transport of munition compounds in the environment.
