Understanding Polars Without Math
A guide to getting the most
from polar diagrams

by Bill & Bunny (B2) Kuhlman, with Bill Kubiak

Finally, a mathless way to get the most from all of those squiggly lines! Through a series of easy lessons, you learn methods of determining a particular airfoil's maximum L/D, and other pieces of information necessary to the design process, including the effects of aspect ratio on performance. This book was written for those who have been "turned off" by the mathematical symbols and formulae of textbooks. We promise - NO MATH!
