Book Description
This paper begins with a brief discussion of the basic ground rules and overall considerations in solid rocket motor design. This discussion includes ballistic design considerations, grain features related to ballistic design and their purposes, primary factors which determine stress and strain levels, and design approaches for avoiding structural weak points. The major section of the paper deals with solid rocket motor propellant grain structural integrity assurance, including materials characterization, structural analysis, and structural capability verification. The topics addressed include viscoelastic material behavior and the requisite thermomechanical characterization testing and analysis approaches; failure criteria and the appropriate testing approaches; experimental structural methods, including in-situ stress and strain measurement technology; and service life considerations.

Book Description
Four approaches for incorporating head and aftend effects on burning surfaces into the computer program, previously described were evaluated. A modified Quasi-Two-Dimensional approach, in which the initial head-end three dimensional burning surface is approximated by a number of planes, and the burning of each of these planes is then evaluated, was selected. The effects of aft-end burning are considered by adapting the present straight-through grain evaluation computer program at the aft-end to consider a variable propellant outside diameter. Photostress evaluations of engine grain designs having star and cylindrical perforated configuration with similar web ratios are described. Results obtained from applying a theoretical elastic analysis to the engine grains used in the Photostress study are reported. An experimental program to determine the effects of propellant defects on engine performance is described. Heat transfer studies were performed to duplicate numerically and by electrical analog the actual thermal conditioning history of an engine grain for which experimental thermal response data was obtained.

Book Description
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.

Book Description
The book follows a unified approach to present the basic principles of rocket propulsion in concise and lucid form. This textbook comprises of ten chapters ranging from brief introduction and elements of rocket propulsion, aerothermodynamics to solid, liquid and hybrid propellant rocket engines with chapter on electrical propulsion. Worked out examples are also provided at the end of chapter for understanding uncertainty analysis. This book is designed and developed as an introductory text on the fundamental aspects of rocket propulsion for both undergraduate and graduate students. It is also aimed towards practicing engineers in the field of space engineering. This comprehensive guide also provides adequate problems for audience to understand intricate aspects of rocket propulsion enabling them to design and develop rocket engines for peaceful purposes.
