When the United States Air Force Academy began teaching astrodynamics to undergraduates majoring in astronautics or aerospace engineering, it found that the traditional approach to the subject was well over 100 years old. An entirely new text had to be evolved, geared to the use of high speed digital computers and actual current practice in the industry. Over the years the new approach was proven in the classrooms of the Academy; its students entering graduate engineering schools were found to possess a better understanding of astrodynamics than others. So pressing is the need for superior training in the aerospace sciences that the professor-authors of this text decided to publish it for other institutions' use. This Dover edition is the result. The text is structured for teaching. Central emphasis is on use of the universal variable formulation, although classical methods are discussed. Several original unpublished derivations are included. A foundation for all that follows is the development of the basic two-body and n-body equations of motion; orbit determination is then treated, and the classical orbital elements, coordinate transformations, and differential correction. Orbital transfer maneuvers are developed, followed by time-of-flight with emphasis on the universal variable solution. The Kepler and Gauss problems are treated in detail. Two-body mechanics are applied to the ballistic missile problem, including launch error analysis and targeting on a rotating earth. Some further specialized applications are made to lunar and interplanetary flight, followed by an introduction to perturbation, special perturbations, integration schemes and errors, and analytic formulation of several common perturbations. Example problems are used frequently, while exercises at the end of each chapter include derivations and quantitative and qualitative problems. The authors suggest how to use the text for a first course in astrodynamics or for a two-course sequence. This major instructional tool effectively communicates the subject to engineering students in a manner found in no other textbook. Its efficiency has been thoroughly demonstrated. Dover feels privileged in joining with the authors to make its concepts and text matter available to other faculties.
Exactly what it says on the tin. Covers how to calculate orbits, how to put things into orbits, how to transfer orbits, how to get stuff to the moon or other planets. Very math heavy as you'd expect, I skimmed most of it because I was really just after an outline.
Enjoyed the historical notes, i.e. "this is how newton/kepler did it" which I'm always fascinated by.
Probably should have brushed up on my calculus before diving into this.
What can I say? There is about 400 years worth of science in this book, a book I bought for pocket change. I do, although, recommend taking differential/integral/vector/multivariable calculus before hand. This book pretty much requires a knowledge of those fields. But, if you're familiar with most calculus, I recommend this book 1) for the price and 2) for a quick reference, especially if you're programming these types of forces in a simulation. Online references are always sufficient, of course, but this book has everything laid out in well ordered fashion.
Pretty good for what it is, but way more maths than I expected before I opening this book. Fortunately, the anecdotes and general insights into orbital mechanics are interesting even if you skip most of the formulas and calculations like I did.
My suggestion to other armchair astronauts: you can play Kerbal Space Program for 4-5 hours and get an intuitive grasp of the concepts here much faster than reading the book.
The "BMW" book is pretty much the best basic astrodynamics and orbital mechanics book ever. It works just as well if not better than many current edition textbooks as a reference, and it's way cheaper!
A great book on astrodynamics. I read nd referred to many times in the course of studies. An subsequently re-read. An easy to follow presentation by experienced instructors.
The fundamental text on orbital mechanics. If you need your missile to go ballistic or just want to throw something at the moon hard enough to hit it, this is a must-read.
For anyone new to aerospace— this book is a great companion and reference. I read it roughly linearly, and i would love to take an online course to actually work all the math as it is intended.
It is a textbook— but richly illustrated and setup in a way that you can really pull knowledge from on demand.
I especially liked the historic background on each section— it lined out who and where in our western and eastern histories made the key discoveries and breakthroughs in understanding.
I read this without any knowledge of calculus, trigonometry, or differential equations (all of which I am now studying). Despite this, the text was illuminating. This is the book that I would recommend to anybody struggling with the idea that the earth might be flat. There could be no more simplified and congenially thorough evaluation and analytical proof of the reality of motion through space.
Obviously this is a very technical book which is advised for people with the academic background (advanced mathematics, physics, etc) to appreciate this book.
That said - it is a very good book to study if you want to master orbital dynamics and many techniques used in the space field. It covers all of the important topics in enough detail that you can go on to specialize or you can begin to apply the concepts.
I did take a class with the original book, back in 1981, and have referred back to the original many times. This book is valuable since it includes a number of very good illustrations - many other books have only a few illustrations. The illustrations have been updated and are better than the original's versions - we have far better tools today than in 1971! We will miss the fun photos of radars and Baker Nunn cameras but they did not add much to the book.
This is an excellent update to a very valuable book that will keep it relevant for the next several decades.
Lo sto leggendo e non l'ho ancora finito... è molto bello perché spiega gli argomenti in maniera chiara, senza dare per scontato nulla, è richiesta (per lo meno fino a dove sono arrivato) solamente una conoscenza di base di fisica e di analisi matematica.
Le figure non sono "belle" ma sono molto chiare.
Unico difetto, non del contenuto, è che l'aspetto delle formule non è molto bello, non so come dire ma sono un po' storte... una riscrittura in LaTeX sarebbe bellissima.
