Available in PDF, EPUB and Kindle. Book excerpt: This research is directed at making direct measurements of the acoustic admittance of flames and interpreting those measurements in terms of flame models. Laser Doppler velocimetry (LDV) instrumentation, pressure detectors, and data analysis techniques were set up and used successfully to measure the acoustic response of a propane/air burner system. Applications of the techniques to solid propellants are described and are the subjects of the continuing research. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The combustion processes of solid propellants and rocket chamber Flows are being analyzed in terms of more complete flame models and fluid dynamics models. The flame structure, surface processes, and liquid layer decomposition of a cyclic nitramine (e.g., RDX) have been modeled. The model includes the partial decomposition of the nitramine molecule in the liquid phase, surface gasification, gas phase decomposition, and oxidation of formaldehyde. Several propellants (e.g., nitramine composite and nitrocellulose-based propellants) produce flame zones which extend well into the main chamber flow field. An analytical model is being developed that considers the effects of chemical reactions (i.e., extended flame zones) in the main chamber flow on the acoustic response of solid rocket motors.

Available in PDF, EPUB and Kindle. Book excerpt: The annual report highlights the progress being made on several concurrent solid propellant combustion mechanism researches. Studies of nitrocellulose-base propellants have produced a broad range of experimental results for platonized and unplatonized propellants. The corresponding mathematical models consider the flame zone processes controlling temperature sensitivity, extinguishment limits, and burning rate. The analytical studies of ignition and burning of porous propellants are producing good agreement with data, new insights into the combustion processes, and establishing regimes where steady-state burning rates are achievable. The work of nonsteady burning has progressed to the point that rocket motor transients can be predicted and dynamic burning rates in a variable throat area, low L* motor can be measured; this work has progressed from the research phase to the development stage. Sub- micron pyrophoric aluminum is being investigated as a means of increasing propellant burning rate.

Download or read book Theory of Solid Propellant Nonsteady Combustion written by Vasily B. Novozhilov and published by John Wiley & Sons. This book was released on 2020-08-21 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite significant developments and widespread theoretical and practical interest in the area of Solid-Propellant Nonsteady Combustion for the last fifty years, a comprehensive and authoritative text on the subject has not been available. Theory of Solid-Propellant Nonsteady Combustion fills this gap by summarizing theoretical approaches to the problem within the framework of the Zeldovich-Novozhilov (ZN-) theory. This book contains equations governing unsteady combustion and applies them systematically to a wide range of problems of practical interest. Theory conclusions are validated, as much as possible, against available experimental data. Theory of Solid-Propellant Nonsteady Combustion provides an accurate up-to-date account and perspectives on the subject and is also accompanied by a website hosting solutions to problems in the book.

Book excerpt: This final scientific report reviews the progress from May 1979 to December 1982 on a program to study various aspects of solid propellant combustion phenomena. The original program included three specific areas of study: Diffusion flame analysis; Kinetic mechanisms of double base propellants; Interaction effects of distributed particle combustion in acoustic environments. The diffusion flame is the controlling mechanism in the combustion of composite propellants. Therefore, a thorough understanding of diffusion flames is prerequisite to understanding solid propellant combustion, and was the objective of one task of the program. The second task of the program was motivated by the desire to better understand transient combustion such as occurs in DDT and combustion instability. Double base propellant combustion is dominated by the flame kinetics which appear to be more easily studied than those of composite propellants. The final task of the program was aimed at understanding the effect of stability additives on combustion instability. During the final year of the contract, work on the first two tasks was discontinued and all work was concentrated on the third task. Interim reports covering the initial work have been published in December 1980 and February 1982. This report summarizes the work performed during the final phase of the contract covering the time from October 1981 through December 1982. Keywords: Solid rocket propellants.
