Overview - PROP_DESIGN
PROP_DESIGN allows for the design of unducted or ducted aircraft propellers with straight or swept blades and constant or elliptical chord distributions. PROP_DESIGN can be used for all altitudes covered by the U.S. Standard Atmosphere of 1976. Efficiencies of approx. 90% are easily attained, even for effective velocities as high as Mach .85.
