The most powerful podded thrusters in use are the four 21.5 MW Rolls-Royce Mermaid units fitted to RMS Queen Mary 2. [1] Mechanical azimuth thrusters can be fixed installed, retractable or underwater-mountable. They may have fixed pitch propellers or controllable pitch propellers. Fixed installed thrusters are used for tugboats, ferries and ...
Azipod is a trademarked azimuth thruster pod design, a marine propulsion unit consisting of a fixed pitch propeller mounted on a steerable gondola ("pod") containing the electric motor driving the propeller, allowing ships to be more maneuverable.
Propulsion thrusters are those thrusters which provide longitudinal motion for vessels as an alternative to traditional propellers. There are a variety of types of propulsion thrusters but the most common form is the azimuth thruster, that can rotate 360 degrees on a vertical axis to optionally produce thrust for maneuvering. (Lindborg, 1997).
McDonald’s is inviting you to make a new set of toys “Part of Your World.” On May 24, McDonald’s announced “The Little Mermaid” Happy Meal, to go with the Halle Bailey-led live action ...
The Mistral class is a class of five landing helicopter docks built by France. Also known as helicopter carriers, and referred to as "projection and command ships" (French: bâtiments de projection et de commandement or BPC) and "porte-hélicoptères amphibie" (PHA) since 2019, a Mistral-class ship is capable of transporting and deploying 16 NH90 or Tiger helicopters, four landing craft, up to ...

The Kort nozzle is a shrouded propeller assembly for marine propulsion. The cross-section of the shroud has the form of a foil, and the shroud can offer hydrodynamic advantages over bare propellers, under certain conditions. Advantages are increased efficiency at lower speeds (<10 knots), better course stability and less vulnerability to debris.
The Z-drive is so named because of the appearance (in cross section) of the mechanical driveshaft or transmission configuration used to connect the mechanically supplied driving energy to the Z-drive azimuth thruster device. This form of power transmission is called a Z-drive because the rotary motion has to make two right angle turns, thus ...
