This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longitudinal combustion instability in a premixed gaseous propellant rocket motor was studied. The chamber length was varied continuously between 3 and 48 inches. A porous media injection plate was used to approximate uniform one-dimensional propellant injection. A showerhead injector was used to determine the influence of combustion zone recirculation on combustion instability. Two propellant combinations were used, methane (40% O + 60% N) and H - air. Results, in the form of instability maps, are presented for combination of the propellants and injection schemes. The two existing gas rocket instability driving mechanisms are presented and discussed. The influence of chemical kinetics on the instability seems to be unimportant and the driving mechanism is an oscillating heat transfer to the injector couples with a pressure oscillation in the combustion chamber to produce unstable combustion.

This book was released on 1966 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of the longitudinal mode of high-frequency combustion instability in a rocket motor burning premixed gaseous propellants were determined experimentally. The experimental observations were compared with the results of a non-linear instability theory based on a chemical kinetic driving mechanism. It was shown that the theory gives the correct waveform for longitudinal instability. In addition the theory gives the correct qualitative dependence of the stability limits on the mean combustion temperature and activation energy. Harmonic mode longitudinal instabilities were observed. The dependence of the stability limits and instability strength on the mean combustion pressure, combustion chamber length, injector and exhaust nozzle was determined experimentally. Based on the general agreement between the experimental observations and theoretical results it is concluded that the appropriate driving mechanism for high-frequency longitudinal gas-phase combustion instability is chemical kinetics.

Available in PDF, EPUB and Kindle. Book excerpt: Initiation of axial combustion instability in an experimental combustor, 40 inches long by 50 inches I.D., containing a radial burning grain, has been studied utilizing a wide variety of composite propellants. Where instability occurred, a correlation was found between the threshold pressure at which instability was first observed and propellant ballistic parameters, notably the linear burning rate. Fast burning propellants, containing either a catalyst or potassium perchlorate, did not sustain axial mode combustion instability. Transverse instability was observed for most non-aluminized propellants in pressure regimes where they were stable to axial combustion instability. An explanation of combustion stability criteria has been sought in terms of either mixing processes within a granular diffusion flame or a thermal explosion process. The granular diffusion flame concept appears thus far to be the more promising explanation; it predicts the stability trends observed in large solid propellant rocket motors. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Since the invention of the V-2 rocket during World War II, combustion instabilities have been recognized as one of the most difficult problems in the development of liquid propellant rocket engines. This book is the first published in the United States on the subject since NASA's Liquid Rocket Combustion Instability (NASA SP-194) in 1972. In this book, experts cover four major subject areas: engine phenomenology and case studies, fundamental mechanisms of combustion instability, combustion instability analysis, and engine and component testing. Especially noteworthy is the inclusion of technical information from Russia and China--a first.
