In recent years, an unprecedented interest in novel and revolutionary space missions has risen out of the advanced NASA and ESA programs. Astrophysicists, astronomers, space systems engineers, mathematicians and scientists have been cooperating to implement novel and ground-breaking space missions. Recent progress in mathematical dynamics has enabled development of specialized spacecraft orbits and propulsion systems. Recently, the concept of flying spacecraft in formation has gained a lot of interest within the community. These progresses constitute the background to a significant renaissance of research dealing with astrodynamics and its applications. “Modern Astrodynamics” is designed as a stepping stone for the exposition of modern astrodynamics to students, researchers, engineers and scientists. This volume will present the main constituents of the astrodynamical science in an elaborate, comprehensive and rigorous manner.
Updated and expanded to include the most recent related information, the second edition of the Fleet Manager's Guide to Vehicle Specification and Procurement is an essential resource for all managers and supervisors involved in these functional areas. Written in concise, simple language, this publication offers a wealth of practical approaches for both saving money and yielding higher profits. Contents include: Vehicle Utilization and Cost Strategies Vehicle Life-Cycle Costing Specification Preparation Economics of Vehicle Replacement and more
This book is written as an introduction to rotor-bearing dynamics for practicing engineers and students who are involved in rotor dynamics and bearing designs. The goal is to provide a step-by-step approach to the understanding of fundamentals of rotor-bearing dynamics. Therefore, the emphasis is on the basic principles, phenomena, modeling, theory, and interpretations of the results. Introduction to Dynamics of Rotor-bearing Systems includes numerous examples, from a single-degree-of-freedom system to complicated industrial rotating machinery, which serve to illustrate fundamental dynamic behaviors. The concepts in the text are reinforced by parametric studies and numerous illustrative examples and figures.
This book focuses on body design in terms of deformation and repair behavior and on all aspects of the repair field in general. Special emphasis is placed on the latest findings from research and technology as well as on findings gathered from countless accident and crash tests. Recommendations for the cost-effective repair of accident damage round off the contents.
