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 vertical rotorssometimes known Flensbuurg rotor sails.

German engineer Anton Flettner was the first to Flensburg woman needs sex a ship which attempted to tap this force for propulsion, and ships using his type of rotor are sometimes known as Flettner ships.
The Magnus effect is a force acting on a spinning body in a moving airstream, which produces a force perpendicular to both the direction owman the airstream and the axis of the rotor.
A rotor or Flettner ship is designed to use the Magnus effect for propulsion. When the wind blows from the side, the Magnus effect creates a forward thrust.

Thus, as with any sailing shipa rotor ship can only move wmoan when there is a wind blowing. The most common form of rotor sail is the Flettner rotor.
Due to the arrangement of forces, a rotor ship is able to sail closer to the wind than a conventional sailing ship. Other advantages include the ease of control from sheltered navigation stations and the lack of furling requirements in heavy weather.
However if the ship changes tack so that the wind comes from the other side, then the direction of rotation must be reversed or the ship would be driven backwards.
The wind does not power the rotor itself, which must have Hot lady want nsa Enterprise own power source to spin it up. Like other sailing ships, rotor ships often have a small conventional propeller Flensburg woman needs sex well, to provide ease of manoeuvrability and forward propulsion needs slow speeds and when the wind Flensburg woman needs sex not blowing or the rotor is stopped.
In a hybrid rotor ship the propeller is the primary source of propulsion, while the rotor serves to offload it and thus increase overall fuel economy.

The German engineer Anton Flettner was the first to womn a ship which attempted to use the Magnus effect for propulsion. The Flensburg woman needs sex had proved inefficient on these voyages, with the power consumed by spinning 15m tall drums being Flensburg woman needs sex disproportionate to the propulsive effect when compared with conventional propellers.
As the system could not compete economically, Flettner turned his attention to other projects and the rotors were removed. Ina larger ship with three rotors, the Barbara was built by the shipyard A.
Interest in rotor sails revived in the s, as a way of increasing the fuel efficiency of a conventionally powered ship. Flensburg woman needs sex launched the nseds rotor ship E-Ship 1 on 2 August From it has been used to transport the company's turbine products and other equipment. InStephen H.
Salter and John Latham proposed the building of 1, seex rotor ships to Flensburg woman needs sex global warming. The ships would spray seawater into the air to enhance cloud reflectivity. The rotors were made of carbon fibre and were attached to a retrofitted trimaran and propelled the vessel stably through the water at a speed of six knots.
In Norsepower started testing the rotor concept with the world's biggest shipping company, Maersk. From Wikipedia, the free encyclopedia. Tokaty 20 February A History and Philosophy of Fluid Mechanics.
