Download or read book Combustion Mechanisms of Wide Distribution Propellants written by Robert A Fredrick (Jr) and published by . This book was released on 1988 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to describe the effects of oxidizer particle size distribution on the burning rate of solid propellants used in rocket motors. Current models over predict the burning rate of wide distribution (wide distribution denotes two oxidizer modes that have extreme differences in mean diameter) formulations by 40 to 200 percent indicating combustion mechanisms unique to this type of propellant. Four sets of AP/HTPB propellants were formulated to control the physical and chemical heterogenities characteristic of the propellant surface using 400 and 20 microns oxidizer particles. The propellants were tested at pressure levels from 0 to 2000 psig. An optical, distance measurement technique was developed and used to measure the local, non-steady surface deflagration of the propellant burning surface. The method uses a laser beam, synchronous detection, and closed-loop tracking to locate the surface in the hostile combustion environment. An acoustic emission technique determined average burning rates. Combustion phenomena were also accessed using high-speed photography and scanning electron microscopy. Keywords: Particle size distribution, Burning rate, Solid propellants, Rocket motors, Combustion mechanisms, AP/HTPB propellants, Laser diagnostics, Acoustic emissions, Scanning electron. (MJM).

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.

Download or read book Solid Propellant Combustion Mechanism Research written by M. Summerfield and published by . This book was released on 1973 with total page 15 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Purdue University has played a leading role in providing the engineers who designed, built, tested, and flew the many aircraft and spacecraft that so changed human progress during the 20th century. It is estimated that Purdue has awarded 6% of all BS degrees in aerospace engineering, and 7% of all PhDs in the United States during the past 65 years. The University's alumni have led significant advances in research and development of aerospace technology, have headed major aerospace corporations and government agencies, and have established an amazing record for exploration of space. More than one third of all US manned space flights have had at least one crew member who was a Purdue engineering graduate (including the first and last men to step foot on the moon). The School of Aeronautics & Astronautics was founded as a separate school within the College of Engineering at Purdue University in 1945. The first edition of this book was published in 1995, at the time of the school's 50th anniversary. This corrected and expanded second edition brings the school's illustrious history up to date, and looks to Purdue's future in the sky and in space.

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.
