2. Marine pump - Wikipedia

   en.wikipedia.org/wiki/Marine_pump

   The rotational energy typically comes from an engine or electric motor. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits. The gear pump is a marine gear pump that uses the meshing of gears to pump ...

3. Marine propulsion - Wikipedia

   en.wikipedia.org/wiki/Marine_propulsion

   A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.

4. Gear pump - Wikipedia

   An exploded view of an external gear pump Fluid flow in an external gear pump Fluid flows from left to right in this internal gear pump. Oil pump from a scooter engine. A gear pump uses the meshing of gears to pump fluid by displacement. [1] They are one of the most common types of pumps for hydraulic fluid power applications. The gear pump was ...

5. Rim-driven thruster - Wikipedia

   en.wikipedia.org/wiki/Rim-driven_thruster

   Rim–driven thruster, presented at SMM 2010 A rim-driven thruster mounted on a swing-out unit (design by silentdynamics GmbH) Voith rim thruster at SMM 2010 in Hamburg. The rim-driven thruster, also known as rim-driven propulsor/propeller (or RDP) is a novel type of electric propulsion unit for ships.

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. 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 ...
