Aerodynamics for Naval Aviators (FAA Handbooks) Review

Aerodynamics for Naval Aviators (FAA Handbooks)
Average Reviews:

(More customer reviews)
Way too many pilots are making it through "professional" flight schools, a few years of instructing, into the commuters and finally into the cockpit of large jets with very little rigorous study of aerodynamics. With the emphasis on conservative training, electronic gadgets and such something is shortchanged and that is fundamentals of aerodynamics. This book is the answer as a text, instructor's aide and desk reference.
The product review infers that this is an FAA publication. Thankfully it is not. Rather it is the text that has lead generations of young Naval Aviation officers from diverse backgrounds into the cockpits of jet fighters operating off of carriers and many other forms of aviation. The preface and title page clearly indicate that it was written by Hugh Hurt (University of Southern California); Hurt notes "The purpose of this textbook is to present the elements of applied aerodynamics and aeronautical engineering which relate directly to the problem of flying operations." In this case the client was the Naval Air Systems Command and the book's mission was to provide the aeronautical knowledge required to transition from a liberal arts major to the deck of a carrier.
When I first bought this book I had been flying for several decades. My regret was that I had not read it earlier. Students who use the book in aviation courses will have a significant advantage in their training. It is a great resource book on all things having to do with how airplanes ( and helos) fly and sometimes do not fly.
Considering that the feedstock of Navy aviation is a diverse group with backgrounds from aero to poly sci and that the demands placed on the graduates are huge, it is not surprising that this book was produced. It does a fantastic job of discussing concepts and then providing the math (most of it far beyond my ability) and graphs. However, the lack of a background in calculus does not prevent the reader from gaining priceless insights into the physics and practice of flying.
Yes the photographs are dated and of planes long sent to the boneyard but the physics of flying have not changed since the earth cooled. In fact, with the current crop of flight instructors so affixed to their digital displays, most civilian students will need to study aerodynamics on their own. Want to understand why Mooney aircraft have so many bent props on the 231/252 series, just spend a few minutes wiht the applied problems in aero and some of the basics.
For me the goal was not to understand every topic covered, but to add to my knowledge base, especially as it relates to the type of flying I normally do, and to have an excellent reference. With that goal this book is great. HIGHLY RECOMMENDED
The author's success is evident in many ways but perhaps most in the fact that after more than four decades it is still the text of choice in many rigorous academic and professional training programs. If I had to pick two books to give a student pilot it would be Richard Bach's Stranger To The Ground and this book. I have also recommended this book to several of my instructor friends as an aid to understanding what they are teaching.

Light This Candle: The Life & Times of Alan Shepard--America's First Spaceman Review

Light This Candle: The Life and Times of Alan Shepard--America's First Spaceman
Average Reviews:

To anyone but a true student of spaceflight history, this might be regarded as a superb biography of an extraordinary man, and it certainly comes very close. Neal Thompson has a punchy, smooth-running style, which obviously reflects his lengthy career as a professional journalist, but just like a journalist it seems he kept his manuscript to himself and well under wraps, and I believe this has proved a sad downfall for an otherwise excellent book. People who know their spaceflight stuff are thick on the ground, but it is very obvious that no one was consulted in order to simply verify the so-called facts about Shepard's NASA career in this book. There are so many elementary errors inherent in this part of the story that it must call into question the reliability of other areas such as his military service, and he deserves better.
The author's descriptions of early spacecraft are incorrect; so too his explanations of the dynamics of space flight and the space environment. I know helicopter pilot Jim Lewis well enough to say that he would be absolutely furious with Thompson's baseless assumption that Gus Grissom blamed Lewis for nearly letting him drown after the hatch blew on his spacecraft. Quite the contrary - Lewis was elsewhere making a valiant but ultimately unsuccessful attempt to save Liberty Bell 7. Any fundamental study of this dramatic event would reveal that Lewis's helicopter did not in fact retrieve Grissom as stated in the book, and his was not the only helicopter on the scene - there were actually three involved. I also feel that far more effort should have been made to research the Mercury flight of Scott Carpenter, rather than reiterating bitter and biased recollections dominating Chris Kraft's account of this flight in his own book. Carpenter successfully brought home a flawed, badly malfunctioning spacecraft, but where is this story? It seems a much-misrepresented confrontation between two personalities is a better scenario to present than the program-saving heroics and expertise of a gentle, courageous astronaut.
The author says he elicited the help of Alan Shepard's family in writing this book, and while I do not doubt the veracity of this statement, I wonder if they feel betrayed by many of the vapid sex "revelations" he felt obliged to relate, which only serve to make this book a poor man's "Right Stuff." I, for one, did not care to know the intimate details of Alan and Louise Shepard's first night together as man and wife. This was just guesswork, voyeuristic journalism at its most revolting, and has no place in such a serious biography. It would also, I am sure, have proved very distressing to the daughters, and such odious reporting is precisely why Shepard would not divulge his life story before he died, and why family members have never cooperated with journalists or biographers before now - and probably never will again. The author also rebuts the whole Shepard/Glenn conflict matrix he carefully makes throughout the book by saying that Shepard was panicked into seeking Glenn's counsel on a delicate matter. This goes absolutely against the grain of both personalities, as pointed out numerous times in his own book. Research and sources please, Mr. Author, not the presentation of presumptions as facts based simply on third-party and questionable hearsay.
My sincere wish is that the author had just allowed someone with a solid knowledge of spaceflight dynamics and history to read the text before he rushed this book into print, because the presence of numerous errors and typos only serves to diminish the full impact of what might have been a truly good biography.
An Australian called Clive James once penned a great book called "Unreliable Memoirs," and I'm afraid this is an alternate title I would have to apply to this book. Nevertheless, it still merits 4 out of 5 for readability, and for finally bringing us the incredible (albeit author-flawed) story of America's first man in space. We can only hope that a corrective rewrite is in the offing. Then, I'm sure, I can probably add that fifth star to the overall rating.

Aircraft Design: A Conceptual Approach (Aiaa Education Series) Review

Aircraft Design: A Conceptual Approach (Aiaa Education Series)
Average Reviews:

Mr. Raymer has managed to explain a very complicated process in a way that is both understandable and interesting. Conceptual aircraft design (i.e., starting with nothing but a set of performance criteria to be met) is a multi-variable problem in which the value of most of the variables depend on other variables. The solution of such problems require initial approximations with subsequent iterations. Mr. Raymer explains the conceptual design process, gives historic values used for first approximations and makes good use of actual examples. Two conceptual designs, one a homebuilt aerobatic aircraft and the other a supersonic fighter, are provided in the Appendix to illustrate the procedures described in the book. I found the book interesting both in subject matter and writing style. Although written as a college textbook, the use of actual aircraft to illustrate various points and the author's obvious desire to be precise about his descriptions makes the book easy to follow and fun to those interested in the subject.

This textbook presents the entire process of aircraft conceptual design - from requirements definition through initial sizing, congfiguration layout, analysis, sizing and trade studies - in the same manner seen in industry aircraft design groups. Interesting and easy to read, it contains more than 900 pages of design methods, illustrations, tips, explanations and equations, and has extensive appendices with key data essential to design. For the third edition, Daniel Raymer has updated his book to reflect advances in technologies such as hypersonics, stealth and STOVL, and design methods including concurrent engineering, cost as an independent variable, and the impact of the factory of the future. With his usual easy-to-read style, he has expanded his treatments of such key areas as jet engine installation, CFD, trim analysis, CAD/CAM, propeller thrust analysis, weights estimation, cost analysis and multivariable optimization.Raymer has added, by popular demand, a step-by-step description of how a typical design is developed (with illustrations), and also describes the technical concepts behind some unusual design approaches such as tailless, canard-pusher, no-lateral-symmetry (Rutan Boomerang), wing-in-ground effect, and the hypersonic waverider. Along with the addition of metric data and equations, more than 30 new illustrations and homework examples have been added.
