Model of Emma Mærsk undergoing testing in a ship model basin. In marine engineering, a ship motion test is hydrodynamic test performed with ship models for the purpose of designing a new (full sized) ship, or refining the design of a ship to improve its performance at sea. [1] Tests are carried out in a ship model basin or "towing tank". [2]
A propeller imparts momentum to a fluid which causes a force to act on the ship. [1] The ideal efficiency of any propulsor is that of an actuator disc in an ideal fluid. This is called the Froude efficiency and is a natural limit which cannot be exceeded by any device, no matter how good it is.
The momentum theory or disk actuator theory – a theory describing a mathematical model of an ideal propeller – was developed by W.J.M. Rankine (1865), A.G. Greenhill (1888) and R.E. Froude (1889). The propeller is modelled as an infinitely thin disc, inducing a constant velocity along the axis of rotation and creating a flow around the ...
Other vessels may have twin, triple or quadruple screws. Power is transmitted from the engine to the screw by way of a propeller shaft, which may be connected to a gearbox. The propeller then moves the vessel by creating thrust. When the propeller rotates the pressure in front of the propeller is lower than the pressure behind the propeller.
Rotor ship E-Ship 1. A rotor ship is a type of ship designed to use the Magnus effect for propulsion. The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion. "The idea worked, but the ...
Two modules of Cometto MSPE series configured with turntable operated by Eisele AG in Maintal.. A self-propelled modular transporter or sometimes self-propelled modular trailer (SPMT) is a platform heavy hauler with a large array of wheels which is an upgraded version of a hydraulic modular trailer.
Trumpeter plastic models of ships are produced in 1:200, 1:350, 1:500 and 1:700 scale, although 1:350 and 1:700 are dominating. Trumpeter has a cooperation with Japanese ship model manufacturer Pit-Road for kits in 1:700 scale. These kits are usually available under the Pit-Road label in Japan and under the Trumpeter label in the rest of the world.
The kit can be built as a full-hull or waterline model. Companies from outside Japan such as Revell and Airfix have begun to produce various 1:350 scale ships as well. Trumpeter have released a large series of models in this scale since the late 2000s including a range of German and Allied World War 2 vessels, modern US Navy, Royal Navy and ...
