This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of the critical diameter, and shock and impact sensitivity of the LOVA-X1A propellant are described. The detonation velocity was determined as a function of charge diameter for the propellant. The critical diameter lies between 0.245 and 0.375 in. for the bare charge. The shock sensitivity for initiating detonation in the propellant was determined by a gap test technique. The results, together with the results of projectile impact tests on solid disks of the propellant determined earlier, are discussed and examined in terms of the sensitivities of materials given in the literature. The critical initiating shock pressure and critical ignition energy are estimated. It is shown that the LOVA-X1A propellant is relatively insensitive to initiation compared to most cast explosives and propellants in use today. The sensitivity of stacked small grains of the propellant to projectile impact was also determined. The tests showed that the response of the grains at a large projectile diameter was always deflagration; whereas at small diameters no sustained reaction was produced. No detonation was produced by the impact. Recommendations for additional studies are given.

Available in PDF, EPUB and Kindle. Book excerpt: Results of work on the Propellant Sensitivity Project with emphasis on the use of gap test and other small scale tests for safety studies are discussed. Measured initiating pressures were highest near the critical diameter of the test material and decreased to their lowest value at an effectively infinite acceptor diameter. The standard confinement of the gap test increased the effective acceptor diameter by a factor of 2.5 for Comp B. Gap test results showed good correlation with large-scale field tests, bluntnosed bullet tests, and the approximately onedimensional wedge test results; it is believed that the gap test measures a 50% initiating pressure close to that for an infinite diameter acceptor. A supplement to the NOL Shock Sensitivity Test for propellants was devised whereby the judicious choice of explosive witness systems makes it possible: (1) to assess the strength of reactions of too low impulse to produce a positive result under the conditions of the standard test, and (2) to measure the sensitivity to shock initiation of substances exhibiting such reactions.

This book was released on 2022-04-01 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Modeling of the Sensitivities of Energetic Materials, Volume 22 introduces experimental aspects, explores the relationships between sensitivity, molecular structure and crystal structure, discusses insights from numerical simulations, and highlights applications of these approaches to the design of new materials. Providing practical guidelines for implementing predictive models and their application to the search for new compounds, this book is an authoritative guide to an exciting field of research that warrants a computer-aided approach for the investigation and design of safe and powerful explosives or propellants. Much recent effort has been put into modeling sensitivities, with most work focusing on impact sensitivity and leading to a lot of experimental data in this area. Models must therefore be developed to allow evaluation of significant properties from the structure of constitutive molecules. Highlights a range of approaches for computational simulation and the importance of combining them to accurately understand or estimate different parameters Provides an overview of experimental findings and knowledge in a quick and accessible format Presents guidelines to implement sensitivity models using open-source python-related software, thus supporting easy implementation of flexible models and allowing fast assessment of hypotheses
Download or read book Solid Rocket Propulsion Technology written by A. Davenas and published by Newnes. This book was released on 2012-12-02 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, a translation of the French title Technologie des Propergols Solides, offers otherwise unavailable information on the subject of solid propellants and their use in rocket propulsion. The fundamentals of rocket propulsion are developed in chapter one and detailed descriptions of concepts are covered in the following chapters. Specific design methods and the theoretical physics underlying them are presented, and finally the industrial production of the propellant itself is explained. The material used in the book has been collected from different countries, as the development of this field has occurred separately due to the classified nature of the subject. Thus the reader not only has an overall picture of solid rocket propulsion technology but a comprehensive view of its different developmental permutations worldwide.
