Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of the combustion characteristics of a Hivelite-based, very-high-burn-rate (VHBR) propellant was conducted. The experiments were performed in a closed chamber, called the VHBR bomb, that was specially designed and constructed for these experiments. The device was designed with the same diameter as the propellant samples in order to maintain one dimensional combustion processes and transient wave phenomena to simplify subsequent interpretation and analysis. Propellant combustion was characterized by a low burn rate (about 1 m/s) until a pressure in the vicinity of 15-20 MPa is reached. After this pressure, which may represent the propellant crushing or break pressure, the combustion rate accelerated to levels from 10 to 180 m/s, depending on other test parameters. Tests conducted at different loading densities indicated that combustion rate was a strong function of pressure. Variation of sample weight at constant loading density demonstrated that increasing the amount of unburned propellant at the time the break pressure was reached also causes burn rate and thrust to increase. A coating that makes the outside surface of the sample slippery tended to reduce the apparent burn rate but use of a coating which retarded transmission of gas pressure along the periphery of the sample increased the apparent burn rate as well as thrust. Change of mounting interface properties caused significant differences in the dynamic characteristics leading to increased thrust.

This book was released on 1977 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Augmentation of solid propellant burning rate often occurs in the presence of strong product gas flow across the burning surface: This phenomenon is referred to as erosive burning. Increasing use of motors with low port-to-throat area ratios (including nozzleless motors) is leading to increased occurrence and severity of erosive burning. A first generation model based upon bending of columnar diffusion flames by a crossflow, permitting prediction of the effect of high-velocity crossflow on the burning rate of a composite propellant given only the zero-crossflow burning rate characteristics, is briefly summarized and compared with data. A second generation model (currently under development) which does not require even zero-crossflow burning rate data, using only composition and particle size as input, is outlined. In addition, a test device permitting extensive characterization of burning rate-pressure-crossflow velocity relationships for various propellants with direct continuous measurement of instantaneous burning rate by high-speed cinematography is described, and results of a series of tests with four propellants are presented. These tests indicate that the first generation composite propellant erosive burning model has reasonable good predictive capability, particularly in the higher pressure region where the propellant combustion is dominated by the propellant heterogeneity.

Available in PDF, EPUB and Kindle. Book excerpt: This third edition of the classic on the thermochemical aspects of the combustion of propellants and explosives is completely revised and updated and now includes a section on green propellants and offers an up-to-date view of the thermochemical aspects of combustion and corresponding applications. Clearly structured, the first half of the book presents an introduction to pyrodynamics, describing fundamental aspects of the combustion of energetic materials, while the second part highlights applications of energetic materials, such as propellants, explosives and pyrolants, with a focus on the phenomena occurring in rocket motors. Finally, an appendix gives a brief overview of the fundamentals of aerodynamics and heat transfer, which is a prerequisite for the study of pyrodynamics. A detailed reference for readers interested in rocketry or explosives technology.

Available in PDF, EPUB and Kindle. Book excerpt: This second edition of the classic on the thermochemistry of combustion now features five new chapters and updated coverage of significant recent developments in the field. Addressing both experimental as well as theoretical aspects, the book covers the thermochemical and combustion characteristics of all important types of energetic materials, such as explosives, propellants, and the new class of pyrolants, as well as related phenomena. It presents the fundamental bases of the energetics of materials, deflagration and detonation, thermochemical process of decomposition and combustion, plus combustion wave structures. The book also goes on to discuss the combustion mechanisms of various types of energetic materials, propellants, and explosives, based on the heat transfer process in the combustion waves. The burning rate models are also presented as an aid to understanding the rate-controlling steps of combustion processes, thus demonstrating the relationships of burning rate versus pressure and initial temperature. As a major topic new to this edition, new propulsion methods such as duct rockets, ramjets, pulse motors and thrusters are described in detail, while appendices on flow field dynamics and shock wave propagation have been added.

This book was released on 1968 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of the research program has been to study the non-steady burning characteristics of solid rocket propellants, both experimentally and theoretically, to establish a basis for avoiding combustion instability in rocket motors and for predicting thrust transients during motor ignition and extinction. A new non-steady burning model for composite propellants was formulated in which the key element, the non-steady heat feedback law from the gaseous flame, was shown to be a function of the instantaneous pressure and burning rate. Solutions to this model showed that burning stability is largely determined by the exothermicity of reactions in the immediate neighborhood of the propellant surface and by the sensitivity of burning rate to surface temperature. The predictions of the model were generally confirmed by T-motor and rapid pressurization experiments. The non-steady burning model was also used to analyze L-star combustion instability in rocket motors and to demonstrate the feasibility of a novel mechanism for suppression of combustion instability by aluminum addition to a propellant.

This book was released on 1995 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes results of plasma propellant combustion studies performed on M5 and JA2 solid propellants. Both static (fixed pressure) and dynamic (variable pressure) closed chamber firings are analyzed to provide insight into the p1asma propellant combustion process. Results indicate that the plasma may influence propellant combustion (as measured by propellant burn rate) early in the combustion cycle, but appears to have little or no impact once ful1 propellant burning begins.
