This is a reminder that PropDesign, an MS-Windows port of Ed Dokus's
DOS/BASIC propeller design program of a few years ago is available.  It
allows one to enter a propeller type (planform, airfoil, number of
blades, etc.) and cruise conditions (airspeed, altitude, etc.).  It
calculates propeller pitch, diameter, chord, thrust and efficiency in
both graphical and tabular form, allowing an experimental aircraft
designer to ask "What if?" without having to carve/bolt on/fly each new
design.

PropDesign is in the public domain and free for the downloading (approx.

600 kB) at http://PropDesign.homepage.com/
