About 15 or 18 years ago, I had the greatest handbook with a million "rules of thumb" concerning aerodynamics. Well, I loaned it out to "someone" and never got it back. Over the years I have tried to find another one and have purchased several books that are so mired in theory as to be nearly worthless. This book had lots of illustrations and simple ways to calculate or extrapolate down and dirty solutions. It was a fairly small paperback. Anybody know what book I am thinking of ?

Hmmmm... I'm guessing that it was either the Aerodynamics book by Frank Zaic called Circular Airflow or it may have been one of the Carstens books that came out in the early 60's. The Zaic book has simple stuff but also gets as complex as you want to while the Carstens book I only saw in a library was short and pretty well down to earth and right to the point. About 30 to 40 pages and thin. The Zaic one is the size of a pocket book, usually orange or red covers and about 1/2 inch thick.

CLose? Do I win a prize?
