Available in PDF, EPUB and Kindle. Book excerpt: Theoretical capability to predict the burning rate of real propellants from their ingredients would be an invaluable aid to formulating new propellants. Despite progress over the last decade on a very few simple ingredients, such as cyclotrimethylenetrintramine (RDX), and a few simple binary mixtures, no general capability of this sort exists today. This shortcoming is not due to insufficient computational resources, but to a lack of understanding of fundamental combustion mechanisms in the condensed phase and surface(gas interlace for typical propellant ingredients and their mixtures. This difficult problem is likely to remain intractable for some time to come. In this report, we demonstrate that our previously published semi-empirical formalism for single ingredients can be success fully extended to treat multi-ingredient propellants. In particular, for purposes of this report, we confine ourselves to nitrate- ester propellants, using MlO, M2, M9, and JA2 as examples. However, the method should also be applicable to other classes of homogeneous propellants and even composite propellants where mixing of ingredients in a surface melt layer or sufficiently small particle sizes remove the multi- dimensional character. The method treats the gas-phase processes on the level of elementary reaction and multicomponent transport. A semi-empirical pyrolysis law coupled with informed estimates of the decomposition products of the condensed phase enables us to finesse the absence of knowledge of the detailed processes occurring in the condensed phase and at the burning surface. Results of a computer code, CYCLOPS, based on this approach, show that both the burning rate and flame structure are well predicted for a series of four U. S. Army gun propellants.
Book Synopsis Overviews Of Recent Research On Energetic Materials by : Donald L Thompson
Download or read book Overviews Of Recent Research On Energetic Materials written by Donald L Thompson and published by World Scientific. This book was released on 2005-08-02 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few books cover experimental and theoretical methods to characterize decomposition, combustion and detonation of energetic materials. This volume, by internationally known and major contributors to the field, is unique because it summarizes the most important recent work, what we know with confidence, and what main areas remain to be investigated. Most chapters comprise summaries of work spanning decades and contain expert commentary available nowhere else. Although energetic materials are its focus, this book provides a guide to modern methods for investigations of condensed and gas-phase reactions. Although these energetic reactions are complex and difficult to study, the work discussed here provides readers with a substantial understanding of the behavior of materials now in use, and a predictive capability for the development of new materials based on target properties.
Book Synopsis Prediction of Advanced Nitramine Propellant Burning Rates with the CYCLOPS Code by :
Download or read book Prediction of Advanced Nitramine Propellant Burning Rates with the CYCLOPS Code written by and published by . This book was released on 2003 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to predict the burning rate of a propellant from its ingredients would be an extremely valuable aid to the formulation of new propellants. We have been developing such a capability over the last 5 years and recently described its use for nitrate-ester propellants. In this report, we first present results of applying this model (the CYCLOPS code) to advanced nitramines propellants, both cyclotrimethyeletrinitramine (RDX) and hexanitrohexaazaisowirtzitane (CL20) oxidizers in an energetic binder made of a bisazidomethylene oxetane-azidomethylenemethyl oxetane (BAMO-AMMO) mixture. A substantial revision in the available gas-phase reaction mechanism previously used for neat RDX was required, necessitating Quantum-Rice. Ramsperger-Kassel calculations for many new reaction paths. The resulting mechanism grew from 45 species and 232 reversible elementary reactions to 80 species and 550 revemible elementary reactions. Burning rates computed by the model compared very well with measured rates for both the RDX- and CL20-based propellants. Temperature profile measurements were available for the RDX propellant only, but the code computations indicated a much shorter dark zone than that measured with microthermocouples. These are the first calculations of burning rates for advanced nitramine propellants, and the results are encouraging.

Download or read book Ignition! written by John Drury Clark and published by Rutgers University Press. This book was released on 2018-05-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly reissued debut book in the Rutgers University Press Classics Imprint is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.

Book excerpt: Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.

Book Synopsis Airlift Doctrine by : Charles Miller
Download or read book Airlift Doctrine written by Charles Miller and published by CreateSpace. This book was released on 2012-08-01 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: n this extremely comprehensive overview of airlift and air mobility, Colonel Miller shows how the worldwide orientation of American foreign policy, the numerous threats to free-world interests, and the speed and complexity of modern warfare have combined with political and resource constraints to produce today's airlift doctrine and force structure. Airlift is the movement of goods and people to where they are needed, when they are needed there. Since the 1920s there has been an evolving awareness and articulation of how to best organize, train, and equip airlift forces for that mission. The worldwide orientation of American foreign policy, the numerous threats to free world interests, and the speed and complexity of modern warfare have combined with political and resource constraints to produce today's airlift doctrine and force structure. Colonel Miller's study traces these many interrelationships to discover what critical airlift decisions were made, why they were made, and what they may mean in the future. Airlift is the backbone of deterrence. A properly structured and equipped airlift force is critical to the successful execution of the national military strategy. How we think about airlift and how we translate those thoughts into a meaningful expression of how to develop, deploy, and employ airlift forces is vital to the national defense. Colonel Miller's study is a definitive step in that important process.
