Boat propellers are available in a wide assortment of sizes and shapes. Sizes are referred to in terms of diameter and pitch. To make the best selection, sync the propeller to the manufacturer’s wide open throttle (WOT) range. The right propeller will turn the minimum engine RPM’s required by the manufacturer with its throttle fully advanced. The second author wrote a program for the described method and designed a propeller for the following case: Engine: 64.30 kW at 3000 rpm (takeoff and climb) 48.53 kW at 2700 rpm (cruise) The diameter R = 1.6 m was selected, and the cruise condition V = 200 km/h was used for the design of the propeller.
Hi everyone!
I'm looking for all CAD software and Codes that are related to marine/ship Propellers (any series) and their capabilities, like an introduction. I want to create the Geometry and so on. does anybody have experience in this field?

Hello,
Prop design is a very complex subject, congratulations for looking to tackle it.

Also, for sort of an introduction to how boat props work, you might see the basic overviews and definitions on this site: https://www.hhprop.com/how-boat-props-work.php
Each prop is ideally designed for the ship it will propel. For much smaller craft the props are pretty generic. But a properly designed prop can add up a lot of positive features over time with reduced fuel costs, reduced maintenance ship-wide (due to reduced vibrations), greater comfort, and maybe ever more power/speed.
Mjtaba jaan, Please try googling ' Open source marine propellers' or ' open source Marine propulsion'.
You will most likely find either a Linux based program or a Fortran based DOS application. They are offered by the universities.
In 1991-92 I designed high speed marine stabilizers -akh, all I can recall is supers-cavitation.
