PropDesign 1.1

PropDesign is a Windows port of Ed Dokus' DOS/BASIC propeller design program. It calculates propeller pitch, diameter, chord, thrust and efficiency when given a propeller type (planform, airfoil, number of blades, etc.) and cruise conditions (airspeed, altitude, etc.). Output is in graphical or tabular form, allowing an experimental aircraft designer to ask "what if?" without having to carve/bolt on/fly each new design.
