| The following articles
are intended to answer a few of the questions you may have
on aspects of model aircraft propeller design and performance.
They are unrestricted as to content, so you may find some
formulae in there. Many people are put off by equations, but
please, where they interest you, work your way through them.
Propellers are one area where you really do need to have the
numbers right.
Most of the articles have been published previously
in Australian Control Line News (acln@ozemail.com.au),
so I recommend this journal to serious control line flyers,
wherever you are.
Also included is "work in progress". This is
mainly the use of Doppler effect to quantitate the performance
of propellers, plus new methods for the design and fabrication
of propellers.

Not included is my book, "Propeller Dynamics".
This may be purchased from me direct,
or from the AMA shop in Muncie, Indiana [fax in USA (765)
289-4248].
After much searching through libraries, I realised
there was no book that gave a non-technical introduction to
the theory of propellers. My book is intended to be read by
the newcomer to propeller theory, but also to include insights
which may either inform or amuse the professional engineer.
My hope was that it would be taken up by the universities
as a primer in aerodynamic propulsion courses, but that has
not happened. Guess I'm ahead of my time, yet again!!
