Book excerpt: This Final Technical Report describes completed research accomplishments and ongoing activities that are focused on the evolution of boundary driven acoustic disturbances in a low Mach number shear flow like that found in the chamber of a solid rocket engine. The completed work (manuscripts in Appendices A and B) focuses on the relatively complex wave systems that appear in a two-dimensional planar shear flow following the refraction of very simple, initially planar axial disturbances. Work in progress emphasizes; (1) the characteristics of acoustic disturbances driven by sidewall mass addition in semi-confined channels and tubes, (2) the role of strongly injected Stokes boundary layers in providing a transition from the acoustic flow to the no-slip condition on the wall, and (3) mathematical methods required to deal with nonlinear processes within an acoustically disturbed flow. The review of our work emphasizes the importance of studying the evolution of boundary driven acoustic disturbances, primarily to gain an understanding of how small burning rate transients (modelled by unsteady wall injection) lead to large engine chamber responses observed in unstable solid rockets.

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.

Download or read book Solid Rocket Propulsion Technology written by A. Davenas and published by Newnes. This book was released on 2012-12-02 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, a translation of the French title Technologie des Propergols Solides, offers otherwise unavailable information on the subject of solid propellants and their use in rocket propulsion. The fundamentals of rocket propulsion are developed in chapter one and detailed descriptions of concepts are covered in the following chapters. Specific design methods and the theoretical physics underlying them are presented, and finally the industrial production of the propellant itself is explained. The material used in the book has been collected from different countries, as the development of this field has occurred separately due to the classified nature of the subject. Thus the reader not only has an overall picture of solid rocket propulsion technology but a comprehensive view of its different developmental permutations worldwide.
Download or read book Transient Combustion in Solid Propellant Cracks written by and published by . This book was released on 1977 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-dimensional theoretical model, incorporating the Noble-Abel dense gas law, has been developed to describe the transient model combustion phenomena inside a propellant crack. The theoretical model can be used to predict wave phenomena, heat transfer from the gas to the propellant surface and associated thermal penetration, flame propagation, and resultant pressurization at various locations along the propellant cavity. Calculations made with the current theoretical model revealed that the internal pressurization rate, pressure gradient, and flame velocity in propellant cracks (for which gases can penetrate) decrease as: the gap width increases, the rocket chamber pressurization rate decreases, and the propellant gasification temperature increases. Additionally, the predicted flame spreading was found to decelerate in a region near the crack tip; this phenomena has been experimentally observed by others.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years the study of nonstationary combustion has been intensely conducted in many countries. This is conditioned by the fact that almost all processes of combustion which occur in rocket engines (ignition, transient conditions of combustion, vibration combustion, extinction, etc.) are related to nonstationary combustion. In the report the theory of the nonstationary combustion of solid rocket propellants is discussed, and experimental data which refer to such combustion behavior are given. From a single viewpoint the majority of the phenomena which occur during the nonstationary combustion of solid rocket propellants is described.

This book was released on 2018-08-20 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study on the fundamental processes involved in fuel decomposition and boundary layer combustion in hybrid rocket motors is being conducted at the High Pressure Combustion Laboratory of the Pennsylvania State University. This research should provide a useful engineering technology base in the development of hybrid rocket motors as well as a fundamental understanding of the complex processes involved in hybrid propulsion. A high pressure slab motor has been designed and manufactured for conducting experimental investigations. Oxidizer (LOX or GOX) supply and control systems have been designed and partly constructed for the head-end injection into the test chamber. Experiments using HTPB fuel, as well as fuels supplied by NASA designated industrial companies will be conducted. Design and construction of fuel casting molds and sample holders have been completed. The portion of these items for industrial company fuel casting will be sent to the McDonnell Douglas Aerospace Corporation in the near future. The study focuses on the following areas: observation of solid fuel burning processes with LOX or GOX, measurement and correlation of solid fuel regression rate with operating conditions, measurement of flame temperature and radical species concentrations, determination of the solid fuel subsurface temperature profile, and utilization of experimental data for validation of a companion theoretical study (Part 2) also being conducted at PSU.
