Available in PDF, EPUB and Kindle. Book excerpt: The research described in this report is directed at obtaining an understanding of the behavior of propellant sprays in a liquid propellant rocket engine under oscillating flow conditions as a means of relating combustion stability to propellant properties and injector design. The report covers: (1) an outline of the work on the instability problem; (2) the combustion instability model; (3) calculation of fluctuations in the vaporization of liquid sprays for axisymmetric injection; (4) preliminary formulation of a transient problem associated with pressure oscillations in a rocket chamber; (5) calculation of Green's function for the transient instability problem; (6) a simple example of the calculation of the spray distribution function and the stability criterion; and (7) perturbation method for calculating stability boundaries. Sections 2 and 3 are related to treating a linear type instability where all oscillations are acoustic in nature. Sec 4 deals with the development of finite amplitude waves. In Sec. 5 a method of solution of the transient instability problem is discussed. Sections 6 and 7 cover a sample calculation of the spray distribution function and stability criterion. Significant results show that droplet vaporization can be a cause of combustion instability and that stability boundaries can be predicted from injector parameters and propellant properties.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this program is the acquisition of detailed analytical and experimental information concerning the mechanisms of energy addition from propellant spray combustion to steady flow fields and propagating pressure disturbances. Data are to be obtained and used to evaluate present or formulate new expressions describing the dynamics that contribute to the coupling processes between the spray and gas flow fields. These expressions appear in steady-state and transient propellant combustion models and bear directly on the prediction of performance and onset of high frequency combustion instability in liquid propellant rocket engines. To overcome past difficulties in comparing analytical and experimental results, an experimental apparatus which produces a monodisperse propellant spray uniformly distributed throughout the combustor has been built. The motor, to be operated as a rocket engine combustor under either stable or transient conditions, provides for optical observation and is extensively instrumented to record pressure wave amplification or decay as a function of parameter variation. Test data (drop diameters, velocity and pressure wave growth or decay as functions of chamber length and initial conditions) can be input to the newly-developed combustion models and the validity of the coupling term expressions evaluated by directly comparing the resulting predictions to experimental data. These newly-developed combustion models are described in detail.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The investigation is concerned with the development of a theoretical model for combustion instability, in the longitudinal mode, occurring in liquid propellant rocket engines that are employed in current practice. Experimental results are used both to help generate realistic physical models for combustion-wave phenomena in heterogeneously reacting systems, and for subsequent verification of theoretical results.

Available in PDF, EPUB and Kindle. Book excerpt: The great engineering achievement required to overcome most of the challenges and obstacles that prevented turning rocket design from art into science took place in Europe and the United States between the 1930s and the 1950s. With the vast majority of the engines currently in operation developed in the “pre-computer” age, there are new opportunities to update the design methodologies using technology that can now handle highly complex calculations fast. The space sector with an intense focus on efficiency is driving the need for updating, adapting or replacing the old modeling practices with new tools capable of reducing the volume of resources and the time required to complete simulations and analysis. This book presents an innovative parametric model applicable to the project of some elements of the liquid rocket thrust chamber with the level of detail and accuracy appropriate to the preliminary design phase. It addresses the operating characteristics and dimensioning of some thrust chamber elements through a set of equations and parameters, which include thrust or propellant characteristics. The model degree of sophistication was adjusted to the requirements of the Project Life Cycle Phase B, while also enabling quick analysis of new configurations from changes in initial project parameters.

Book excerpt: Information resulting from this study will allow formulation of new and very general analytical models and criteria to permit a priori design of reliable and stable liquid rocket motors and supersonic air-breathing engines required for future weapons delivery systems. Specifically, the objective of this program is the acquisition of experimental data on the mechanisms of propellant spray combustion energy addition to steady flow fields and propagating pressure disturbances. The data will be used to evaluate expressions describing the dynamics that contribute to the coupling processes between the spray and gas flow fields. These expressions form the basis of steady-state and transient propellant combustion models that bear directly on the problem of predicting performance and the onset of high frequency combustion instability in liquid propellant rocket engines.

Download or read book Ignition written by John Drury Clark and published by Rutgers University Press. This book was released on 2018-05-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly reissued debut book in the Rutgers University Press Classics Imprint is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.
Download or read book Fundamental Concepts of Liquid Propellant Rocket Engines written by Alessandro de Iaco Veris and published by Springer Nature. This book was released on 2020-09-26 with total page 747 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for students and engineers who design and develop liquid-propellant rocket engines, offering them a guide to the theory and practice alike. It first presents the fundamental concepts (the generation of thrust, the gas flow through the combustion chamber and the nozzle, the liquid propellants used, and the combustion process) and then qualitatively and quantitatively describes the principal components involved (the combustion chamber, nozzle, feed systems, control systems, valves, propellant tanks, and interconnecting elements). The book includes extensive data on existing engines, typical values for design parameters, and worked-out examples of how the concepts discussed can be applied, helping readers integrate them in their own work. Detailed bibliographical references (including books, articles, and items from the “gray literature”) are provided at the end of each chapter, together with information on valuable resources that can be found online. Given its scope, the book will be of particular interest to undergraduate and graduate students of aerospace engineering.
