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.

Available in PDF, EPUB and Kindle. Book excerpt: Calorimetry, as a technique for thermal analysis, has a wide range of applications which are not only limited to studying the thermal characterisation (e.g. melting temperature, denaturation temperature and enthalpy change) of small and large drug molecules, but are also extended to characterisation of fuel, metals and oils. Differential Scanning Calorimetry is used to study the thermal behaviours of drug molecules and excipients by measuring the differential heat flow needed to maintain the temperature difference between the sample and reference cells equal to zero upon heating at a controlled programmed rate. Microcalorimetry is used to study the thermal transition and folding of biological macromolecules in dilute solutions. Microcalorimetry is applied in formulation and stabilisation of therapeutic proteins. This book presents research from all over the world on the applications of calorimetry on both solid and liquid states of materials.

This book was released on 1971 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive study of the decomposition of ammonium perchlorate (AP) with and without additives has been reported in several recent review articles, and it has been recognized that the reaction mechanism during the catalyzed decomposition of AP differs from that of the uncatalyzed reaction. In the authors studies of the physical and chemical parameters that control ignition and deflagration of solid propellants, they have concentrated on quantitative examination of the potential contribution of surface-catalyzed reactions between AP, catalyst, and gaseous organic molecules, representative of the fuel binder in an operational propellant.

Available in PDF, EPUB and Kindle. Book excerpt: 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 was released on 1999 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study to characterize the low-temperature reactive processes for o-AP and an AP/HTPB-based propellant (class 1.3) is being conducted in the laboratory using the techniques of simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS) and scanning electron microscopy (SEM). The results presented in this paper are a follow up of the previous work that showed the overall decomposition to be complex and controlled by both physical and chemical processes. The decomposition is characterized by the occurrence of one major event that consumes up to (almost equal to)35% of the AP, depending upon particle size, and leaves behind a porous agglomerate of AP. The major gaseous products released during this event include H2O, O2, Cl2, N2O and HCl. The recent efforts provide further insight into the decomposition processes for o-AP. The temporal behaviors of the gas formation rates (GFRs) for the products indicate that the major decomposition event consists of three chemical channels. The first and third channels are affected by the pressure in the reaction cell and occur at the surface or in the gas phase above the surface of the AP particles. The second channel is not affected by pressure and accounts for the solid-phase reactions characteristic of o-AP. The third channel involves the interactions of the decomposition products with the surface of the AP. SEM images of partially decomposed o-AP provide insight to how the morphology changes as the decomposition progresses. A conceptual model has been developed, based upon the STMBMS and SEM results, that provides a basic description of the processes. The thermal decomposition characteristics of the propellant are evaluated from the identities of the products and the temporal behaviors of their GFRs. First, the volatile components in the propellant evolve from the propellant as it is heated. Second, the hot AP (and HClO4) at the AP-binder interface oxidize the binder through reactions that preferentially strip the hydrogen from the binder and yield HCl and H2O with some oxidation of the carbon from the binder. Third, the o-AP in the propellant decomposes in the same manner as in neat o-AP. Finally, AP-derived gaseous products interact with other ingredients in the propellant.

This book was released on 1973 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new, comprehensive steady-state model describing the burning of non-metalized, unimodal ammonium perchlorate (AP)-polymeric composite solid propellant has been developed and shown to yield better results than previous models. This new model incorporates a near-surface AP decomposition flame perturbed by fuel vapor diffusion (after Chaiken) followed by a granular diffusion flame (after Summerfield), and is termed the 'modified granular diffusion flame' (MGDF) model. The MGDF model permits numerical prediction of the influence of pressure, AP particle size, mixture ratio and propellant initial temperature on propellant burning rate. While the new model has proven notably successful, evaluation of the capabilities of it and other models is constrained by the limited existing data base. (Modified author abstract).
