It both pulls water in and pushes it out to create forward thrust. Each blade has a pressure differential where the bottom of the blade ... WebPOD is one type of azimuth propulsion consisting of an integrated electric motor / propeller unit mounted on the same shaft, installed in a gondola under the stern of the ship. The gondola revolves around a vertical axis suitably orienting the propeller so as to control the direction of motion.

WebJun 19, 2024 · A propeller is a type of fan that propels fluid by pushing against it, converting rotational force into a linear motion. An impeller is a type of rotor that is typically part of a pump and creates a sucking force, i.e. drawing liquid into a vehicle or engine. WebThe propeller has been both custom-designed and wake-adapted, providing close interaction with the hull. Multiple series of tests were performed both on the hull and the propeller, and adjustments and modifications were made in each case to arrive at reasonable optimum performance characteristics.
