Book excerpt: The morphological and chemical characterization of M30 propellants recovered after conventional and plasma ignition with polyethylene (PE) terephthalate (Mylar) in an interrupted closed bomb (extinguished at pressures between 35 and 100 Mpa) has been performed. It has been reported that burning rate augmentation appears to occur during the plasma event, but there was no evidence for post-plasma augmentation. For the extinguished grains from PE plasma ignition, there appears to be removal of nitroguanidine (NQ) crystals in the perforations. Also, hot embedded particles and increased surface area were observed, instead of the melt layer normally obtained with conventionally ignited samples. Although extensive chemical characterization has been performed, there appears to be very little chemical difference between the burned surfaces and subsurfaces of the plasma and conventionally ignited samples. Scanning electron microscopy (SEM) analysis revealed that although a melt layer is present on the surface of M30, it is immeasurably thin. Moreover, the SEM analysis showed that NQ depletion in the perforations was most evident at the lowest blow-out pressure used (35 Mpa) and seemed to diminish at higher pressure, apparently becoming obscured by "normal" burning processes. Thus, plasma-propellant interactions and associated effects may occur only very early during ignition, and it may be that there are few decomposition products remaining near the surfaces of the samples.

Book Synopsis Experimental Investigation of the Interaction of Electrothermal Plasmas with Solid Propellants by :
Download or read book Experimental Investigation of the Interaction of Electrothermal Plasmas with Solid Propellants written by and published by . This book was released on 2007 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report measurements of the interaction between plasma radiation and solid propellant. We made heat flux measurements of the electrothermal plasma jet impinging on a sensor mimicking a disk of propellant. We made planar laser-induced fluorescence images of NO, a JA2 decomposition product at the propellant surface. High speed video imaging of the propellant surface and scattering of ejected particles was used to study how the propellant surface evolves during exposure to plasma radiation. During the radiation interaction scattering particles and NO appeared between 100 and 150 microseconds after the beginning of the discharge and propagated away from the propellant surface. The ejected material occurred in identifiable structures that are irregular in shape and distribution suggesting that ejection occurred at semi-discrete locations on the surface rather than uniformly. During the plasma firing the propellant surface changed markedly by forming irregularly shaped decomposition structures that grew in size over the course of the discharge. No correlation was observed between the structure of the ejected material and the decomposition structures formed on the propellant surface during the discharge. After the plasma discharge, the propellant continued to react, with bubbles forming on the surface up to 9 ms after the discharge finished.
Book Synopsis Factors Influencing Ignition Delay Time of Composite Solid Propellants by : S. Atallah
Download or read book Factors Influencing Ignition Delay Time of Composite Solid Propellants written by S. Atallah and published by . This book was released on 1970 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal events occurring on an near a propellant surface during ignition were observed simultaneously using an optical detector operating over two narrow wavelengths: 3.79 micrometers which is free of interfering CO2 and H2O thus representing radiation from the surface and 0.43 micrometers which detects the CH radical in the flame above the surface. Aluminized and non-aluminized PBAA/AP propellants were heated using an arc-imaging furnace with argon or oxygen flowing near the propellant surface at different velocities and irradiation levels. Combustion products of CO-O2-N2 mixtures of varying compositions were also used to heat the propellants convectively in a hot gas tunnel. Furthermore, the non-aluminized propellant was ignited chemically with fluorine. Differences in the ignition delay time as measured by the two detectors were observed under certain conditions. Factors affecting these differences and the magnitude of the delay time are discussed. (Author).
Book Synopsis Propellants and Explosives by : Naminosuke Kubota
Download or read book Propellants and Explosives written by Naminosuke Kubota and published by John Wiley & Sons. This book was released on 2015-04-23 with total page 560 pages. 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.
