  2. Marine propulsion - Wikipedia

    en.wikipedia.org/wiki/Marine_propulsion

    Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats , most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller , or less frequently, in pump-jets , an ...

  3. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    MHD propulsion has been considered as the main propulsion system for both marine and space ships since there is no need to produce lift to counter the gravity of Earth in water (due to buoyancy) nor in space (due to weightlessness), which is ruled out in the case of flight in the atmosphere.

  4. Voith Schneider Propeller - Wikipedia

    en.wikipedia.org/wiki/Voith_Schneider_Propeller

    Voith Schneider Propeller. The Voith Schneider Propeller (VSP) is a specialized marine propulsion system (MPS) manufactured by the Voith Group based on a cyclorotor design. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously.

  5. Air-independent propulsion - Wikipedia

    en.wikipedia.org/wiki/Air-independent_propulsion

    Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.

  6. Pump-jet - Wikipedia

    en.wikipedia.org/wiki/Pump-jet

    A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and ...

  7. Propulsion - Wikipedia

    en.wikipedia.org/wiki/Propulsion

    Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of a motor or engine turning a propeller , or less frequently, in jet drives, an impeller .

  8. Integrated electric propulsion - Wikipedia

    en.wikipedia.org/wiki/Integrated_electric_propulsion

    An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...

  9. Combined diesel and gas - Wikipedia

    en.wikipedia.org/wiki/Combined_diesel_and_gas

    Principle of a CODAG system, with two speed diesel gearboxes. Combined diesel and gas (CODAG) is a type of propulsion system for ships that need a maximum speed that is considerably faster than their cruise speed, particularly warships like modern frigates or corvettes.
