11 of 13 people found the following review helpful By JPH on December 12, 2009
Format: Hardcover
After reading this book thoroughly, I found 68 major errors of fact, a list of which I have sent to the author. Errors include, for example, statements that the propeller thrust line was angled to direct its slipstream through the rotor disk (p.21), or a given rotor collective pitch change operates in the reverse sense in an autorotating (Autogiro) rotor compared to a propulsive (helicopter) rotor (p.41). Such errors, and there are plenty more where they came from, clearly indicate Ord-Hume does not understand the subject on which he writes.

The book frequently presents speculation as fact, draws unsupportable conclusions, contradicts itself in different discussions of the same event, and makes statements clearly disproved by accompanying illustrations, among other failings. Overall, the book comes across as a rough draft clearly not ready for prime time.

Ord-Hume is apparently an aviation writer "of great repute" and references all the right people and publications through the course of "Autogiro". How he arrived at the mess that is this book is a question best left for him to answer. The best course of action Ord-Hume can take to protect his reputation is to collect and destroy every copy of this book that he can find.

As is quite common with much to do with the Autogiro, individuals who are expert in a particular aspect of aviation attempt to extend that expertise into this subject matter. "Autogiro" clearly shows the results of such an attempt when not thoroughly researched, checked, and presented.

Format: Hardcover Verified Purchase
While there may or may not be the issues that the reviewer above notes, this book is absolutely unparalleled as a guide to Autogiro manufacturers and the variety of machines they made, and attempted to market. This book is also a superb history of invention in the toughest of economic times, and will answer questions no other book does about why this technology did not take hold. Buy this book along with the (collectible, out-of-print) Smithsonian-published volume on this subject by Peter Brooks, and you will have all you need to read to understand this fascinating topic.
