Azimuth thruster - Wikipedia

English inventor Francis Ronalds described what he called a “Propelling Rudder” in 1859 that combined the propulsion and steering mechanisms of a boat in a single apparatus. The propeller was placed in a frame having an outer profile similar to a rudder and attached to a vertical shaft that allowed the device to rotate in plane while spin was transmitted to the propeller. The modern azimuth thruster using the Z-drive transmission was invented in 1951 by Joseph Becker, th
