While
I was a little hesitant to add a book of this price
range, my mind was quickly changed after just a
few minutes of review. It is very well done and
up to date. It is also one of the very few aircraft
design books I have found which is at the same time
necessarily technically oriented, but also not beyond
the understanding of those without an advanced mastery
of mathematics. Besides just theory, Fundamentals
of Sailplane Design also covers many of the practical
matters for both the aspiring designer and the sailplane
pilot who wants to obtain a mastery of how and why
his/her craft performs as it does.

From
the preface: Accomplished soaring
pilots appreciate the need for a sound understanding
of the technical aspects of their sport.
This book, the definitive text on sailplane
design will provide the interested pilot
with a better understanding of his or her
aircraft. To make the material accessible
to those without an engineering background,
an emphasis is placed on physical understanding
and visualization. Mathematics is held to
a minimum.
The book will be of even more interest to
those interested in designing sailplanes.
Because it draws on decades of experience
developed at the German Akafliegs, the material
will help the experienced engineer to quickly
develop a practical understanding of the
considerations that go into the design of
a high performance sailplane.
This third edition reflects the technical
developments since the last German language
edition of 1984. the design data tables
and 3 view drawings now contain entries
for over 150 aircraft. By presenting this
edition in English, it is hoped that this
unique collection of sailplane design information
will become accessible to a wider audience
worldwide. |
