rotor ship การใช้

• Rotor ships use mast-like cylinders for propulsion.
• Rotor ships can tack much closer to the wind, 20 to 30?
• Rotor ships typically use rotor sails powered by a motor to take advantage of the effect.
• Except for rotor ships using the Magnus effect, every sailing ship has a provisions, including fresh water.
• The German wind-turbine manufacturer Enercon launched and christened a new rotor ship, E-Ship 1  see opening image, this article  on 2 August 2008.
• In the earliest published studies, John Latham and Stephen Salter proposed a fleet of around 1500 unmanned Rotor ships, or Flettner ships, that would spray mist created from seawater into the air.
• Assisted by Albert Betz, Jakob Ackeret, and Ludwig Prandtl, Flettner constructed an experimental rotor vessel; October 1924 the Germaniawerft finished construction of a large two-rotor ship named " Buckau ".
• In 2007, Stephen H . Salter and John Latham proposed the building of 1, 500 robotic rotor ships to Discovery Project Earth; The rotors were made of carbon fibre and were attached to a retrofitted trimaran and successfully propelled the vessel stably through the water at a speed of six knots.
