  2. Forces on sails - Wikipedia

    en.wikipedia.org/wiki/Forces_on_sails

    The analysis of the forces on sails takes into account the aerodynamic surface force, its centre of effort on a sail, its direction, and its variable distribution over the sail. Modern analysis employs fluid mechanics and aerodynamics airflow calculations for sail design and manufacture, using aeroelasticity models, which combine computational ...

  3. Wind-assisted propulsion - Wikipedia

    en.wikipedia.org/wiki/Wind-assisted_propulsion

    The mechanical means of converting the kinetic energy of the wind into thrust for a ship is the subject of much recent study. Where early ships designed primarily for sailing were designed around the sails that propelled them, commercial ships are now designed largely around the cargo that they carry, requiring a large clear deck and minimal overhead rigging in order to facilitate cargo handling.

  4. Oceanbird - Wikipedia

    en.wikipedia.org/wiki/Oceanbird

    Oceanbird is a concept for wind-powered cargo vessels under development by Wallenius Marine.The concept aims to lower emissions by up to 90 percent [1] [2] and the design was developed in collaboration with KTH Royal Institute of Technology and Swedish maritime technology company SSPA.

  5. Turbosail - Wikipedia

    en.wikipedia.org/wiki/Turbosail

    According to the Cousteau Society, "when compared to the thrust coefficient of the best sails ever built (Marconi or square types, i.e. ships of the American Cup [sic] or the Japanese wind propulsion system) that of the turbosail is 3.5 to 4 times superior and gives the system a unique advantage for the economical propulsion of ships."

  6. Sail - Wikipedia

    en.wikipedia.org/wiki/Sail

    A sail is a tensile structure, which is made from fabric or other membrane materials, that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or ...

    The Energy Department has tallied nearly $6 billion of investments to develop offshore wind over the last few years, including in 17 manufacturing sites and at 15 ports.

  8. Wind-powered vehicle - Wikipedia

    en.wikipedia.org/wiki/Wind-powered_vehicle

    Wind-powered vehicles derive their power from sails, kites or rotors and ride on wheels—which may be linked to a wind-powered rotor—or runners. Whether powered by sail, kite or rotor, these vehicles share a common trait: As the vehicle increases in speed, the advancing airfoil encounters an increasing apparent wind at an angle of attack ...

  9. High-performance sailing - Wikipedia

    en.wikipedia.org/wiki/High-performance_sailing

    18ft Skiff in Kiel Harbor. High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail.
