A parametric ROV thruster propeller. The design assumes the ROV moves slow when compared to an RC boat. The propeller is more similar to a tug than a speed boat. Close to equal efficiencies in both directions of operation
Using at 750KV brushless motor the propeller and nozzle provided 14N of thrust in both directions drawing 6 amps at 12volts.
Number of blades, prop diameter and thickness, pitch, shaft hole are all modifiable in the openSCAD file.
printed using .1mm layer thickness, using platform support density of 20% on a MOST delta printer.
